                              YUPITERU MVT-7100 GENERAL DESCRIPTION

The MVT-7100 hand held receiver from YUPITERU is a follow on from their
previous  outstanding models. The MVT-7100 has continuous frequency
coverage from 100KHz to  1650MHz, with modes of AM, Narrow FM, Wide FM,
Upper Side Band (USB) & Lower Side Band (LSB). There are 1000 memory
channels provided in 10 banks of 100 into which you can store frequency
& mode while 10 programmable search banks are also available.

Please look after the packaging you receive your YUPITERU MVT-7100 in,
it may be needed should it be necessary to return the unit to the place
of purchase and you may also find it of value should you ever 'trade in'
or sell your MVT-7100.

Please look after your YUPITERU MVT-7100 with care, avoid getting the
unit wet (try not to use it in the bath - it is has been known to have
submerged receivers arrive for repair !) and also direct sunlight, in
particular car dash boards.  Taking care of your receiver will also
maintain its value should you ever wish to sell or part exchange the
set.


Those of you familiar with English instructions translated and printed
in Japan will know  that in most cases they leave a lot to be desired
(after saying that their English is better than my Japanese !), we hope
you will find these instructions far more comprehensive and
understandable. Please read them carefully. Compared to some receivers
the MVT-7100 is one of the easier ones to program and operate, (who said
that !) however we do appreciate that some of the operations can be
"complicated", especially to the newcomer and many faults which owners
report are operations that have been carried out incorrectly. Should
your MVT-7100 not do what it apparently should, please try again reading
the instructions slowly before calling your dealer. Owners of previous
Yupiteru models should have little trouble in operating this new set.


I hope you find this instruction booklet easy to follow, whilst some
parts may seem long winded I have tried to explain the procedures in a
manner which will allow users of varying 'scanner' know-how get the best
out of the MVT-7100 as quickly as possible. For the experienced user
some explanations may seem unnecessary and drawn out but we know from
experience that no matter how hard you try you cannot answer every
bodies questions.   Any comments (or corrections !) would be most
welcome.

Happy Scanning.



			  SUPPLIED ACCESSORIES


The MVT-7100 is supplied with the following accessories:-

4 Ni cad AA size batteries Mains Power supply unit/Battery Charger (12
volts DC, 200mA) DC Lead with cigar lighter plug Telescopic antenna Belt
Clip Carry Strap Ear piece Instruction booklet

NI CAD BATTERIES The ni cads supplied are not factory charged and may
require a good 15 hour charge with the charger supplied while the set is
switched off before they can be used.  You will find that recharge able
batteries will give far better results if every now and again you fully
discharge  them. Try to avoid mixing Ni cad batteries purchased at
different times together, you may not get the maximum performance
available if you do.

MEMORY BACKUP The memory backup battery will retain frequencies stored
in memory for about 7 days should the ni cads loose there charge or are
removed. This backup battery will be charged each time an external 12v
source is connected for at least one hour.

The Batteries will not be charged when the set is turned on. 

Do not use the mains adaptor/charger with alkaline batteries fitted.

If the Ni cad batteries are not charged within 7 days of going "flat"
frequencies stored in memory channels will be lost.

REPLACING BATTERIES To replace the supplied batteries with either
recharge able or alkaline batteries remove the battery cover and place
the four batteries into the rear of the receiver ensuring that the
correct polarity is observed and replace the battery cover. A tactile
means of identifying the plus, and minus poles may be ascertained in the
following manner. open the battery compartment, and examine the
interior. You will find that the space where the batteries are has along
one side, rounded studs, and bowed-out bits of metal. The studs
represent plus, the metal bowed-out sections, minus. You can insert the
battery-cell in the following manner. Place the plus side of the cell in
the compartment so that it's facing one of the rounded studs on the
inside of the case. Then press the cell home, it will but up against the
minus contact, and be held in. Be sure that the flap of plastic which
will aid in removing the pack is tucked under the first set of cells.
Follow this procedure for installing the remaining 3 cells.



                                   CONTROLS ========

 1. Rotary Tuning Dial The  rotary  tuning  knob  has several functions
on  the MVT-7100:-

MANUAL MODE: The tuning knob allows you  to tune up or down from the
displayed frequency in the increment steps chosen.

MEMORY MODE: Turning the knob allows you to move up or down through the
memory channels.

SCAN & SEARCH MODE: Turning the knob when the MVT-7100 has stopped on a
transmission will restart the scan or search in the direction chosen.

MODE SELECTION: Used for the selection of AM, Narrow FM, Wide FM, USB or
LSB when rotated after FUNC + MODE

INCREMENT STEP SELECTION: Used for the selection of any one of the
various increment steps when rotated after pressing the STEP button.

The rotary knob can be used for scrolling through frequencies entered
into the Search Pass facility and  in conjunction with the C/AC key when
correcting a keyboard entry. This latter function is unusable if you
can't see the display.

 2. Power On/Off & Volume Turning clockwise turns the set on and
increases the volume. Turned fully anti-clockwise the receiver will be
turned off.



 3. Squelch Control Turned fully anti-clockwise the squelch is off and
constant background "noise" will be heard. To eliminate the noise and
allow the MVT-7100 to scan or search turn clockwise until such time as
the "noise" disappears. The further clockwise the less sensitive the
MVT-7100 becomes & only stronger signals will be heard.

 4. BNC Antenna Socket The MVT-7100 is supplied with 1 telescopic
antenna which is connected at this point.  It is possible to connect an
alternative antenna to the set using this connector.

 5. Backlight The backlight will only remain lit whilst the button is
pressed.

 6. Monitor Pressing the MONI key effectively opens the squelch fully
while pressed.

 7. Key Lock To prevent accidental operations the keypad can be disabled
by moving Key lock switch up to the "on" position showing a red dot. To
restore the keypad the key lock switch has moved back down.

 8. Reset Button. Pressing this recessed button with a fine pointed
object will result in the MVT-7100's Central Processor Unit (CPU) being
re-set. This will clear all memory channels and also re-set. the 10
search banks to the factory pre-set.  This button should be pressed if
the MVT-7100 appears to lock up or  not accept frequencies, bear in mind
however that  all stored information will be lost so it may be a good
idea to record all the stored frequencies first.

9. Speaker Self Explanatory we think !

10. Carry Strap Hook

11. Ear piece/External Speaker socket. 3.5mm Jack This a a 3.5mm
standard socket. The ear piece supplied, headphones or external speaker
may be connected to this socket but  will disconnect the main speaker.
The impedance should be 8 Ohms.

12. 12 Volt External Power Jack The centre pin is positive. Used to
connect the mains power charging unit or DC cigar lighter lead to the
MVT-7100. Care must be taken to ensure the correct DC voltage (11-15
volts) is applied. When connected to this socket the external source
will charge the internal nickel cadmium batteries. Do not connect an
external source to the MVT-7100 when alkaline (non recharge able)
batteries are fitted. A full charge will take approximately 12-15 hours.
Try not to overcharge the batteries, while this will not cause major
damage, prolonged and constant overcharging can increase the temperature
of the batteries to a point where they may explode.

                      KEY PAD CONTROLS ===============

The key pad consists of 20 keys most of which have at least two
functions. The secondary function is used when pressed in conjunction
with the FUNCTION key at the bottom right of the key pad.

The primary operation of each key is shown on the button itself  while
the secondary function of each key or button is shown in light blue
below each key.

         A description of each key is as follows:-

                   PRIMARY KEY FUNCTIONS =====================

      Keys numbered 1 to 0 including . (decimal point) These are used to
enter frequencies, memory channels, scan & search banks. These keys are
arranged, tact illy as follows. 1 through 3 the top row running left to
wright from the key located in the upper left-hand corner. Thus, with
the scanner facing you, the antenna jack oriented on the left of the
scanner, the top-left hand button is #1. 4, 5, and 6 are located below
#1 through #3. The key-pad is arranged like a touch-tone pad on a
telephone, not usual for this kind of equipment. Thus, 7, 8, and 9 are
the third row of keys down beginning from the left-most key.

Pressing keys 1 to 0 followed by SEARCH or SCAN will result in the
MVT-7100 searching or scanning those banks selected. The search button
is the key in the upper-right hand corner, whilst the scan button is
directly below the search key.


                       SRCH (SEARCH) Press once to start either the
search or programmed band search.

If you press the Search key when in manual mode with a frequency shown
in the display the MVT-7100 will start to search up or down (you can
change the direction if you wish with the rotary knob or up/down
arrows). No bank numbers will show at the upper right of the screen. The
up and down arrows are the keys located on the lower-left hand corner of
the unit. When pressed after a single bank number (i.e. 0 to 9) the
MVT-7100 will search between the two frequencies programmed into that
particular bank. The bank selected to be searched will show in the upper
right of the display.

 search when Pressed whilst searching will stop the search and set the
scanner for browse mode. .


                            SCAN Pressing this key once starts the
MVT-7100 scanning the memory channels. Pressing whilst the unit is
scanning will stop the unit and return to memory mode. Remember, this
key is directly below the search-key.

                            STEP This key is located third key down from
the search, 3 down on the right-hand column. This key cannot be used
easily without access to the display. (hint) If you want to preset some
steps be sure that certain frequencies you have installed are set to a
desired step. More on this later. This key is used In conjunction with
rotary dial (or up/down keys) used to change the selected increment step
which will be shown in the top left of the display.

  Pressing the STEP key will start the currently selected increment
steps to start flashing, by turning the rotary knob on the top of the
set or by using the direction arrows on the keyboard you can scroll
through the alternate choices, when the chosen increment step is
displayed press the red ENT (Enter) key. The enter key is located in the
second column on the right, bottom key.


                      MR (MEMORY READ) This key is located directly
below the Step key, or fourth down on the right. If you wish to go
straight to any one of the 1000 memory channels simply press the channel
number then MR. As you press the channel number the 'digits' will appear
in the main part of the display but when you press the MR key this will
change to the frequency in the chosen channel, with the channel number
now showing on top left of the display

If you are in Manual mode pressing the MR key will take you into Memory
mode with the currently selected memory channel showing on the screen.
You can scroll through the memory channels by turning the rotary knob on
the top of the set or using the up/down keys. This is where some
additional comments may be valuable for users of the scanner in the
dark, or for those of you who have difficulty in reading the display.
The mr key cycles the scanner between the frequency-display, and search
mode, and memory-access mode. There are  2 possible settings.

1. when you have selected 4 or less banks for scanning, the set will
sycle through all the channels selected. When pressing MR, you will be
in a position to display all the channels whether full, or not. 2.
Pressing this button again will display the last displayed frequency you
have entered from manual mode. From here on, the mr button sycles
between the last frequency entered in manual, and the last channel
possitioned over in memory. In the latter state, the scanner will
display all the scanned channels in memory, depending on which banks are
selected to be scanned. This gets kind of interesting, as it provides an
audible means of determining how many channels are in a given bank.
Let's suppose you are scanning the first bank, and it contains 8
channels, all of which are am. For the sake of argument, lets suppose
that bank 10 is programmed with 8 channels of fm broadcast. Good. Now,
we have a way of locating the channels in the bank we want to program
later. Ok, so first we set to scan banks 1, and 10. Now, we get into
memory mode by tapping the mr button. It will then   be possible to use
either the arrow-keys, or the rotary knob to select up the frequencies
in memory. It is easy to count the number of am channels, and see what
the last channel in memory is. As you move through the selection, there
is a slight hiccough in the un- squelched sound between channels. When
you reach the last channel of a bank programmed in, this noise smoothens
down. As you carry on rotating the knob you will hear the programs of
broadcast from the fm side, you will confirm for your self, and know you
have passed the number of channels you have entered. Ok, so, you can now
carry on working with the scanner, having checked out the number of
channels you have filled up in a particular bank. You can move to the
next available channel for programming, and continue searching. The next
channel you program into memory will automatically fill in where you
last set the selector. So, be sure that you are positioned over an empty
set of channels to avoid scrolling over pre-set. channels in memory.
Another way is to simply get into memory mode without selecting up a
scan increment. Then, you can switch through the bank as follows.
program channel 1 by pressing 1, and the mr key. This will put you into
1. You then count 8 spaces with the rotary knob, and move one more to
the right. This will put you over channel 9, the next one to be filled
with the results of a search. This will give you an alternative means of
keeping track of your work.

If you are in Memory mode pressing the MR key takes you back into Manual
mode. The frequency displayed will be the last one you selected in
Manual mode. This is a handy way for checking out which channels you
have programmed in before a search and find mission. Remember, the last
channel you programmed in last will remain in manual display.


                      UP & DOWN ARROWS These are located respectively
lower-left key and up one, and the lower-left-hand key itself. As with
the rotary dial on top of the set the direction arrows have several uses
in different modes. That is, they do everything the rotary knob does.

MANUAL MODE: Pressing either key allows you to tune up or down from the
displayed frequency in the increment steps chosen.

MEMORY MODE: Pressing either key allows you to move up or down through
the memory channels.

SCAN & SEARCH MODE: Pressing either key when the MVT-7100 has stopped on
a transmission will restart the scan or search in the direction chosen.

MODE SELECTION: Used for the selection of AM, Narrow FM, Wide FM, USB or
LSB when pressed after FUNC + MODE

INCREMENT STEP SELECTION: Used for the selection of any one of the
various increment steps when pressed  after the STEP button.

The direction arrows are also used with the Search Pass Read key (in
English it means you can recall which channels you have told the
receiver to miss/jump over when searching), these two keys are used in
conjunction with the C/AC key when correcting a keyboard entry.


                            C/AC Correction key, see pages 16 & 17. This
key is located to the left of the enter key. It is also useful in
putting frequencies into pass-memory. More on this later.

                            ENT Enter key. Used to enter Frequencies,
Increment steps and Receiving modes. This key is second from the right,
bottom row.

                            FUNC Located in the lower-right-hand corner.
Perhaps the most important key on the scanner. Pressed first when you
wish to use the secondary function of each key, details of which follow.



                  SECONDARY KEY FUNCTIONS ======================= In all
cases to access any one of the facilities detailed below the FUNC key
lower-right-hand corner, must be pressed first.

                        ATT (1 key) Attenuator. When selected ATT will
appear in the display. The attenuator can be selected on any individual
memory channel or frequency. In most cases the attenuator should be left
'off', if however strong signals are present it is possible that some
interference may occur. To reduce the strength of signal and reduce the
possibility of interference the attenuator should be selected.  Remember
however that pressing FUNC + ATT will only activate the attenuator for
that particular channel/frequency, no other channels or frequencies will
be affected. If you wish to activate the attenuator for a different
channel and frequency you must select the memory channel the press FUNC
+ ATT.  To turn the attenuator off, select the channel, ATT will show in
the display then press FUNC + ATT again. ATT will clear from the screen
indicating that the attenuator is no longer selected on that channel..
See page 35. In some cases, this key provides an audible clue as to its
result. The back ground noise in the radio will diminish when this key
is used.

                       DELAY (2 Key) The delay facility will cause the
MVT-7100 to pause for approximately 4 seconds after a transmission has
ended and before it continues to scan or search. Without delay selected
the pause time is around 2 seconds. DELAY will show in the display.
Pressing FUNC + DELAY again returns the set to normal mode. The
attenuator has a global function when in search mode. That is, if you
are searching a pre-set. pattern of frequencies, you will attenuate the
entire search. Thus, every channel you enter into memory for future
scanning will be attenuated, unless you change it after the fact.

                        See Page 35 Default is off.


                        SKIP (3 Key) When FUNC + SKIP is pressed in
either Scan or Search mode this will cause the MVT-7100 to continue
scanning or searching after approx. 5 seconds from when it stopped on
that channel or frequency even if the transmission has not finished.
SKIP will show in the display. Pressing FUNC + SKIP again returns the
set to staying on a channel for the entire duration of the transmission.
See Page 35 Default is off.

                       PRI (SRCH Key) Selects the monitor of the
priority channel. See pages 21 & 22 for more on programming the Priority
channel. Default is off.


                        SAVE (4 Key) Selects and cancels the save
function. See page 36. Default is off

                        BEEP (5 Key) Turns the Keyboard beep on or off.
If BEEP is showing at the bottom of the display then the sound is on and
a Beep sound will be heard each time a key is pressed. If BEEP is not
showing in the display then no sound will be heard. See pages 35 & 36.
The beep function is an extremely useful aid in determining the
operating mode of the scanner. Default is beep

                        PGM (6 Key) Used to select memory channels for
the Program Scan mode. See pages 26 & 27. Default no memory selected

                       MW (SCAN Key) Memory Write. Used when you wish to
store a displayed frequency into a specific memory channel.  See pages
18, 19 &32 for further details. Memory is empty at initial purchase.

                       M*VFO (7 Key) Transfers the frequency of a memory
channel into manual mode when you will then be able to tune up or down
from that particular frequency. Started with func. See page 20.

                       M-SCAN (8 Key) Mode Scan. Used to start the Mode
Scan facility. See page 28. default is off

                       P-SCAN (9 Key) Program Scan. Used to start the
Program Scan. See page 26 & 27.

                      MODE (STEP Key) Invoked with func. and Used in
conjunction with either the rotary knob on the top of the set or with
any of the direction keys allows you to change the mode of reception to
either Wide FM, Narrow FM, AM, Lower Side Band (LSB) or Upper Side Band
(USB) on any frequency. See page 13. Default is off

                        MHz ( * Key) In conjunction with the C/AC key
can change the MHz digit of the display. See page 17.

                        SPR (0 Key) Search Pass Read (what !). A new
facility on the MVT-7100 is that you can specify certain frequencies
(not channels) to be missed when searching. These can be frequencies
with permanent interference on or maybe busy channels you just want to
jump over. The Search Pass Read Key in conjunction with the Rotary tuner
or direction arrows allow you to see which frequencies you have
instructed the MVT-7100 to miss. For more details see pages 33 & 34. A
useful trick is to dump all of your preveously-scanned channels into
pass-memory so you won't duplicate your work. Default is off


                        BW (MR Key) In conjunction with Func.
Bandwrite. Used for programming the frequency limits within Search
banks. See pages 30 & 31.

                      PASS (C/AC Key) In conjunction with Func. Used for
'locking out' any memory channel or channels you do not wish to monitor
in the Scan Mode. Also used to lock out specific individual frequencies
(up to 500) when searching. See pages 25, 33 & 34.




                YUPITERU MVT-7100 OPERATION ===========================




To turn the set on slowly rotate the volume knob clockwise. Then rotate
the squelch control fully anti-clockwise. Adjust the volume control to
the desired level (not too loud though) and to silence the background
noise rotate the squelch control clockwise, at some point the "mush"
will disappear.

                 PRE-PROGRAMMED FREQUENCIES ===========================

Whilst all 1000 memory channels are empty when you first turn on your
MVT-7100 (or press the reset button !) it has been pre-programmed at the
factory with 10 search bands which are in most cases unsuitable for the
U.K. listener.  To search one of these banks simply press the bank
number (e.g. 1)  followed by SEARCH  or bank9 press 9 followed by
SEARCH. Further details on searching and programming your own search
parameters follow in a separate section but these are the pre-programmed
limits.

Search Band  Start Freq -  Stop Freq     Step Size     Mode

Bank  1          76.00  -  107.75MHz    50KHz Steps     WFM Bank  2
108.00  -  142.00MHz    50KHz Steps     AM Bank  3         144.00  -
146.00MHz    20KHz Steps     NFM Bank  4         146.00  -  154.65MHz
10KHz Steps     NFM Bank  5         156.00  -  162.05MHz    12.5KHz
Steps   NFM Bank  6         175.75  -  221.75MHz    50KHz Steps     WFM
Bank  7         430.00  -  440.00MHz    20KHz Steps     NFM Bank  8
450.0125-  451.50MHz    12.5KHz Steps   NFM Bank  9         850.025 -
859.9875MHz  6.25KHz Steps   NFM Bank 10         903.0375-  904.9875MHz
12.5KHZ Steps   NFM


Trying to search Bank 2, the whole of the VHF airband is rather a waste
of time, as not only are the pre-programmed parameters far too wide, the
increment steps are in 50KHz, when here in the United Kingdom we use
25KHz steps so the chance of monitoring active frequencies are rather
slim. It is advisable when searching to keep the limits to just a few
MHz and therefore increase the chance of locating new frequencies.
Further details on programming your own search parameters follow.

                   MANUAL MODE OPERATION =====================

Before we look at how to enter and receive frequencies we shall quickly
look at how we select the correct mode of reception and the desired
increment steps. These can be changed after we have entered a frequency.


                      MODE SELECTION. ==============

To change the reception mode from that shown on the right of the screen
press the FUNC + MODE key. The mode currently selected together with the
step size to the left will now flash, by rotating the tuning dial or
pressing the direction keys you can select any one of the alternative
modes available. Once the desired mode is shown press the ENT key. Note
that different step sizes may be associated with each mode



                 INCREMENT STEP SELECTION. =========================

To change the increment step selection from that shown on the top left
of the screen press the STEP key. The increment steps will now flash, by
rotating the tuning dial or pressing the direction keys you can select
any one of the alternative steps available. Once the desired step size
is shown press the ENT key.

       The following increment steps are available:-

                  Wide FM    50KHz, 100KHz Narrow FM  1KHz, 5KHz,
6.25KHz, 9KHz, 10KHz, 12.5KHz, 20KHz, 25KHz, 50KHz & 100KHz LSB & USB
As Narrow FM but with the additional choice of 100Hz & 50Hz ***In ssb
modes, you are defaulted to 50hz. This for easy resolution of ssb
signals. See references to "browse." NOTE: 50Hz & 100Hz can only be
selected in USB or LSB

         In WFM only 50KHz & 100KHz can be selected This is a tricky one
for screenless usage. You can't hear any change when you rotate the
knob, or use the step keys in step mode. I have found the only solution
is to pre-set. a number of searches with pre-set. steps. For example,
let's suppose you need to set up a search in the aviation portion of the
band. You will need a 25khz step. Once you have this step pre-set. in a
search, you can always get to this step in the following manner. 1. go
to an aviation search mode you know has been set up correctly. 2. enter
a frequency in manual mode, next, either set up a search from that
frequency, or prepare the set to program another bank. See Programming
scanner banks. You will then already be in the predetermined step.



                    ENTERING FREQUENCIES ====================

To enter a frequency in Manual (or VFO) is a simple matter. It can be a
good idea to first ensure that the correct mode and desired increment
step are selected but these can be changed as required after any
frequency entry. Simply key in the frequency required using the
numerical key pad followed by ENT.   As you press each number it will
appear on the screen and flash. When you press ENT it will add any
trailing zeros and stop flashing. The audible clue is a double beep. An
error will be a double beep followed by a lower-pitch beep.


                          EXAMPLE To tune the MVT-7100 to 81.3MHz, WFM
mode (assuming the set is currently tuned to 144.00MHz, WFM, 50KHz
steps)

                       1. Press STEP 2. Rotate the tuning knob until
100KHz is shown 3. Press ENT 4. Press 8 1 . 3 5. Press ENTER


If the incorrect mode has been chosen you can change to the correct mode
by pressing FUNC + MODE then using the rotary knob followed by ENT when
correct mode is shown. You will soon be able to tell by ear which mode
has been selected. But they run as follows. From the am setting,
rotating the knob clock-wise, the next mode is lower side band, upper
side band, wide-band fm, followed by narrow-band fm. The display then
repeats itself as you rotate the knob.


                          EXAMPLE To tune the MVT-7100 to 118.025MHz, AM
mode (assuming the set is tuned to 81.30Mhz, WFM, 100KHz following the
above example 100KHz steps)

                    1. Press FUNC + MODE 2. Rotate the tuning knob until
AM is displayed In this case 2 clicks to the right. 3. Press ENT 4.
Press STEP 5. Rotate the tuning knob until 25KHz is shown 6. Press ENT
7. Press 1 1 8 . 0 2 5 8. Press ENT If the set was already in AM mode
and 25KHz or 12.5KHz steps then procedures 1 to 6 need not have been
carried out A clue to screenless usage. As you step through the mode
selections, the sound in the speaker will give you a clue as to which
mode you have selected. Fm, and NBFM are the loudest, with am, and ssb
being quieter, ssb the quietest of the modes. Another way to test is to
use a signal. If a whistle is heard in the speaker, you are in SSB mode.

As a little exercise try the previous  example but this time enter 50KHz
at step 5 and see what happens when you press ENT at the end !

          NOTE:- ( A little bit waffly this bit !) 118.025MHz is a 25KHz
channel spacing and if you have 50KHz or 100KHz selected it will round
itself to receive the nearest frequency because the larger number (50 or
100) does not divide into the smaller. Likewise if you try and enter a
12.5KHz spaced frequency (e.g. 455.6125MHz) when 25KHz or larger
increment steps are selected it will not be accepted. Within the United
Kingdom the VHF/UHF spectrum is mainly divided into 12.5KHz, 25KHz or
50KHz channel spacing, selecting 12.5KHz will always allow you to enter
the exact frequency as they are all divisible by 12.5KHz. Just to add
wood to the fire a 12.5KHz channel spaced frequency will not be accepted
exactly if any of the smaller increment steps down to 1KHz are chosen.
With a little practice you will soon get the hang of it !



               ROTARY TUNING / MANUAL TUNING
=============================

If you wish to use either the rotary tuning dial or the direction keys
you can tune up or down from the displayed frequency in Manual mode.
Each single turn of the dial or press of the key will increase or
decrease the frequency by the increment steps chosen. To change
increment steps simply press the STEP rotate the tuning knob to the
desired steps and press ENT.


                          EXAMPLE: If you manually tune to 7.051Mhz, USB
and 50Hz steps, each clockwise turn of the rotary knob or pressing the
"up" direction key will increase the frequency by 50Hz. Note that ssb
defaults to 50hz. Each anti-clockwise turn or pressing of the "down"
direction key will decrease the displayed frequency by 50Hz.



                  CORRECTING A WRONG ENTRY ========================

Should you realize you are entering an incorrect frequency the easiest
thing to do to correct your mistake is, continue, Press ENT and then
start again making sure you press the correct keys second time around,
if that is not simple enough you can press the C/AC (Clear/All Clear)
key TWICE while the display is flashing and BEFORE you press ENT. You
will then be returned to the previous frequency displayed and you can
start again.

However if the above escape routes are not challenging enough the
"wizkids" at Yupiteru have provided another alternative:

By pressing the C/AC (Clear/All Clear) Key while the display is flashing
and BEFORE you Press the ENT key you can, by using the direction keys
and rotary knob correct any digit on the screen, however it has to be
said this is far more long winded than just starting all over again, but
for the record here's what to do.........

                          EXAMPLE. You intended to enter 128.00 but
accidentally keyed in 138.

         1. Press C/AC while 138 is still flashing (The 8 will now flash
a little quicker than the rest of the display) 2. Press the * to select
the 3 digit. This will now flash a little quicker. 3. Using either the
rotary dial select the correct digit, in this case 2 or just press the 2
key 4. Press ENT 5. Complete the entry of 128.00 by pressing the "."
then ENT



                          EXAMPLE You key in 345.875 but intended to
enter 354.875 .

       1. Press C/AC while 345.875 is still flashing (The 5 will now
flash a little quicker than the rest of the display) 2. Press the * 3
times to select the 5 digit. (This will now flash a little quickerker).
3. Using either the rotary dial select the correct digit, in this case 4
or just press the 4 key 4. Press the * to select the next digit left
(This "4" will now flash a little quicker) 5. Using either the rotary
dial select the correct digit, in this case 5 or just press the 5 key 6.
Press ENT 7. Complete the entry by pressing the ENT key.



    CORRECTING OR ADJUSTING THE MHz DIGIT(S) AFTER ENTRY
====================================================

                          EXAMPLE. In manual mode the displayed
frequency is 144.00Mhz but you wish to change this to 194.00Mhz

       1. Press FUNC + MHZ (the first "4" will flash) 2. Press * to
select the next digit 3. Using the rotary dial select 9 or just press
the 9 key. (The 9 will now flash) 4. Press ENT to complete

               You are now tuned to 194.00Mhz


                          EXAMPLE. In manual mode the displayed
frequency is 468.955Mhz but you wish to change this to 145.955Mhz

       1. Press FUNC + MHZ (the first "8" will flash) 3. Using the
rotary dial select 5 or just press the 5 key. 2. Press * to select the
next digit 3. Using the rotary dial select 4 or just press the 4 key. 2.
Press * to select the next digit 3. Using the rotary dial select 1 or
just press the 1 key. 4. Press ENT to complete

              You are now tuned to 145.955Mhz Much simpler to simply
re-program by typing the desired frequency, plus enter. In manual mode,
there is no long-term memory, and you aren't compromising anything but
the last entry in manual mode. So, these corrective tricks will probably
be of no real use.




  STORING FREQUENCIES IN MEMORY CHANNELS FROM MANUAL MODE
=======================================================

The MVT-7100 has 1000 memory channels, (plus one other when you count
the priority channel) organized in 10 banks of 100 channels into which
you may program any frequency and mode, attenuator settings can also be
stored. Memory channels are shown as a three digit number on the left of
the display. It can be a good idea to group types of frequencies
together, for example, store all your VHF airband frequencies in one
bank, all the UHF airband frequencies in another and so forth.

To store a frequency in a memory channel it is first necessary to follow
the procedures for manual tuning described earlier. It is then a simple
case of informing the MVT-7100 which memory channel you wish to store
the frequency in.

It must be remembered that storing a frequency in a memory channel will
overwrite any information that is already stored in that memory channel.
When you first use your MVT-7100 all the memory channels are empty (an
empty memory channel displays 000.000.0MHz) so no damage can be done,
but once in "full swing" be careful not to overwrite a frequency by
storing something else in that channel.

                          EXAMPLE To store 123.50MHz, AM mode, in
channel 13. (assuming the set is in AM, if not refer to the earlier
section on selecting the correct mode and increment step size)


                     1. Press 1 2 3 . 5 2. Press ENT 3. Press 1 3 4.
Press FUNC + MW

The MVT-7100 will confirm the entry by a double beep (if the sound is on
!) and temporally show the memory channel on the left of the screen then
return to normal Manual mode.


                          EXAMPLE To store 441.8125MHz, NFM mode in
channel 127 (assuming the set is currently displaying 123.50, AM and
25KHz increment steps following the previous example)

                    1. Press FUNC + MODE 2. Rotate the tuning knob until
FM is displayed 3. Press ENT 4. Press STEP 5. Rotate the tuning knob
until 12.5KHz is shown 6. Press ENT 7. Press 4 4 1 . 8 1 2 5 5. Press 1
2 7 6. Press FUNC 7. Press MW



           MEMORY STORAGE - CONSECUTIVE CHANNELS
=====================================

A bit difficult to describe this one without being too long
winded.......

By pressing FUNC + MW without specifying a channel whilst a frequency is
displayed in manual mode will store this frequency shown into the LAST
MEMORY CHANNEL DISPLAYED in memory mode - so if memory channel 066 was
displayed in either memory mode or scan mode and you have manually
entered 129.875MHz, pressing FUNC + MW will store 129.875MHz in channel
066 overwriting what was there before. Subsequent presses of FUNC + MW
will result in 129.875MHz also in channels 67, 68, 69, 70 and so forth.

So if you want to store a set of frequencies in consecutive channels the
following routine can be used:-

           1. Enter first frequency to be stored 2. Enter the channel
number you wish to start at 3. Press FUNC + MW 4. Enter second frequency
to be stored 5. Press FUNC + MW 6. Enter third frequency to be stored 7.
Press FUNC + MW

After each press of FUNC + MW the channel number will appear on the
screen for a short moment.

.....and so forth BUT REMEMBER that storing a frequency in a  memory
channel will overwrite any information that is already stored in that
memory channel and if you do not enter a specific channel at operation 2
above then the MVT-7100 will start to store frequencies from the last
memory channel that was displayed on the screen.


If you are in Memory mode pressing the MR key takes you back into Manual
mode. The frequency displayed will be the last one you selected This is
where some additional comments may be valuable for users of the scanner
in the dark, or who may have difficulty in reading the display. The mr
key cycles the scanner between the frequency-display, and search mode,
and memory-access mode. In the latter state, the scanner will display
all the scanned channels in memory, depending on which banks are
selected to be scanned. This gets kind of interesting, as it provides an
audible means of determining how many channels are in a given bank.
Let's suppose you are scanning the first bank, and it contains 8
channels, all of which are am. For the sake of argument, lets suppose
that bank 10 is programmed with 8 channels of fm broadcast. Good. Now,
we have a way of locating the channels in the bank we want to program
later. Ok, so first we set to scan banks 1, and 10. Do this by tapping 1
followed by 0, then the scan/mw key. Now, we get into memory mode by
tapping the mr button. it will then be possible to use either the
arrow-keys, or the rotary knob to select up the frequencies in memory.
It is easy to count the number of am channels, and see what the last
channel in memory is. As you move through the selection, there is a
slight hiccough in the unsquelch sound between channels. When you reach
the last channel of a bank programmed in, this noise smoothens down. As
you carry on rotating the knob you will hear the programs of broadcast
from the fm side, you will confirm for your self, and know you have
passed the number of channels you have entered. Ok, so, you can now
carry on working with the scanner, having checked out the number of
channels you have filled up in a particular bank. You can move to the
next available channel for programming, and continue searching. The next
channel you program into memory will automatically fill in where you
last set the selector. So, be sure that you are positioned over an empty
set of channels to avoid scrolling over pre-set. channels in memory.
Another way is to simply get into memory mode without selecting up a
scan increment. Then, you can switch through the bank as follows.
program channel 1 by pressing 1, and the mr key. This will put you into
1. You then count 8 spaces with the rotary knob, and move one more to
the right. This will put you over channel 9, the next one to be filled
assuming this space to be empty. This will give you an alternative means
of keeping track of your work. Remember that the last frequency
searched, and stopped at will be the one displayed when next you enter
manual mode by tapping the mr key. So, you can then enter that
frequency in the next available space. Take it one step further, let's
suppose you have a notion to set up another bank with a selection of
things from other banks. This can be done in the same manner. By going
to a channel with a frequency you want in your scan memory, you can use
the funct-vfo to move that frequency into your manual mode. Then, you
can program it to the new location, leaving it where it was as well. An
example: You want to move the frequency stored in channel 3 to channel
342. First, key up #3 followed by mr. Then, func 7, followed by 342 func
mw. The scanner will beep twice, and you will have the frequency stored
in channel 3 also available in 342.

                 RECALLING A MEMORY CHANNEL ==========================

Any one of the 1000 memory channels can be recalled.  If you wish to
recall channel 13 simply press 1 3 + MR. The MVT-7100 will now be in
MEMORY MODE and the display will show the channel number and frequency
stored in it.

In Memory Mode you can use either the rotary tuning dial or the
direction arrow keys to select any channel.  Each single turn of the
dial or press of the key will move to the next or previous channel.


To change from MANUAL (VFO) Mode to MEMORY Mode or Vice-versa simply
press the MR key.


TRANSFERRING A FREQUENCY FROM A MEMORY CHANNEL TO MANUAL MODE
=============================================================

If you  wish to transfer the contents of a memory channel into the
MANUAL (VFO) mode simply press FUNC + M*VFO. You may then either tune
up/down or search from the displayed frequency in manual mode.

                          EXAMPLE Transfer the frequency contained in
Channel 013 to manual mode

1. Press 013 + MR. (To recall channel 013 if not already on that
channel) 2. Press FUNC + M*VFO


The Display will still show the same frequency but the memory channel
number, in this case 013 will be replaced by the currently selected
increment step.



                 CLEARING A MEMORY CHANNEL ==========================

If you wish to clear the contents of a memory channel press FUNC + MW
when the channel you wish to clear is displayed. Once cleared the
display will show 000.000.0MHz.


When a frequency has been deleted it will continue to be received until
a different channel has been selected manually or by scanning.

                          EXAMPLE To clear memory channel 013.

1. Press 1 3 + MR. (If this channel is not already selected) 3. Press
FUNC + MW Another sequence of keystrokes may make this procedure easier
for non-screen display usage. Let's suppose you want to clear out the
frequencies out of bank 5. You have decided you want to reuse this bank,
rather than keeping the bank for what you originally put in it. first
enter 5, then mw, followed by mr. Then func followed by mw. The beeps
will confirm your actions. You will hear a double beep when the
frequency and channel have been deleted. To en sure you don't remove a
channel from another bank you wish to preserve, repeat the above
exactly. By keying in 5 followed by mw, you will ensure that you are
over a channel in the bank you want to remove. When you have finished
deleting all the channels in the bank, an error beep will sound. Course,
if you are deleting 100 channels, you will have to use 500 keystrokes.

        PRIORITY MEMORY CHANNEL - FREQUENCY STORING
===========================================

One additional memory channel, channel number 1000 is available as a
Priority channel. Any frequency and mode within the receivers coverage
can be stored in this channel and monitored every 5 seconds irrespective
of whether the unit has stopped on any other frequency or is in Manual,
Scan or Search mode.

           Don't Forget to set the correct mode.


                          EXAMPLE To store 158.35MHz as the Priority
frequency

                 1. Press 1 5 8 . 3 5 + ENT 3. Press 1 0 0 0 4. Press
FUNC + MW   (P ch will temporally show & the display will then return to
manual mode)


             TO MONITOR PRIORITY MEMORY CHANNEL
==================================

To set the receiver to monitor the Priority channel press FUNC + PRI.
PRI will appear in the bottom centre of the display. Pri is the
search-key upper-right-hand corner. The Priority channel will be checked
for activity every 5 seconds, this will cause a slight "break" during
the reception of any other transmissions. If the Priority channel is
active then this frequency will be received, once the transmission on
the Priority channel has ended the set will return to the previous mode
of operation.

The Priority channel can be monitored in any mode, Manual, Scan or
Search.



         TO CHECK THE CONTENTS OF PRIORITY CHANNEL
         =========================================

If you wish to see which frequency is currently stored in the Priority
channel recall channel 1000 as you would any other memory channel press
1000 + MR.


    When the Priority channel is recalled "P ch" will be displayed
rather than channel 1000.



                      MEMORY SCANNING ===============

The memory channels in the MVT-7100 are organized in 10 banks of 100
channels. Once you have programmed frequencies into the MVT-7100 memory
it is possible to scan either all the channels or a selection of banks.

                 Bank 1 = Channels 000-099 Bank 2 = Channels 100-199
Bank 3 = Channels 200-299 Bank 4 = Channels 300-399 Bank 5 = Channels
400-499 Bank 6 = Channels 500-599 Bank 7 = Channels 600-699 Bank 8 =
Channels 700-799 Bank 9 = Channels 800-899 Bank 0 = Channels 900-999

If you wish to scan the entire contents of the memory simply press the
SCAN key.  You may have to adjust the squelch control to allow the set
to scan through the channels.

The display will show each channel number and frequency as it scans
through the banks.  If you have frequencies in all 10 banks the display
will also show all the bank numbers across the top.

When a transmission is detected on one of the frequencies the receiver
will stop on that particular channel until either the transmission ends
or you either rotate the rotary dial on the top of the set or press the
direction arrow keys to start scanning again in either up or down
through the channels.

If you have activated the Priority channel (see previous section) there
will be a short break during the reception of signals when the receiver
"jumps" to the Priority channel to see if that channel is active.


If there are no frequencies stored in memory channels "Error" will be
displayed when the SCAN key is pressed

                          EXAMPLE

To start scanning the all the memory channels that have been programmed.

                       1. Press SCAN

"ALL PASS" will be displayed when the SCAN key is pressed if all the
channels within the banks selected have been passed (Locked Out)


When the set stops on a transmission the bank number will flash
indicating which bank the channel received is in.


                     TO  STOP  SCANNING ==================

Pressing the SCAN key whilst scanning will stop the set on whichever
channel it happens to be on and return you to Memory Mode. You can
select other memory channels from this point by either using the rotary
dial, direction arrows or by entering the desired channel followed by
MR.

You can also press the MR when scanning and you will be returned to
memory mode, just the same as pressing the SCAN key as above. Key in a
memory channel followed by MR when scanning and you will go direct to
the chosen channel.

If you wish to return to Manual mode when Scanning press the MR key
twice.

             SELECTIVE  MEMORY  BANK  SCANNING
==================================

Unfortunately you can only specify a maximum of any 4 banks out of the
10 to scan in this manner.

By pressing the SCAN key you scan all the memory channels that you have
programmed frequencies in to. However more often than not you may not
wish to scan the entire contents. If for example you have grouped
frequencies together and all your local amateur frequencies are in Bank
1 then you may wish to scan just that one bank or you may wish to scan
the banks that contain your VHF & UHF airband frequencies. By simply
pressing the bank number or numbers prior to pressing the SCAN key you
can tell the MVT-7100 which banks to scan.

                          EXAMPLE To scan banks 1, 2 and 0.

                       1. Press 1 2 0 2. Press SCAN


The MVT-7100 will now only scan banks 1, 2 & 0, you will notice that the
display will only show these 3 banks at the top of the screen. When the
set stops on a transmission the bank number will flash indicating which
bank the channel received is in.

If you had selected to scan just bank 7 by pressing 7 + SCAN then the
small figure 7 on the display would show and you would only be scanning
channels 600 - 699.


               MEMORY CHANNEL PASS (LOCKOUT)
=============================

In the previous example (Selective Memory Bank Scanning) we have seen
how we can program the MVT-7100 to scan just one or up to 4 individual
banks. You may also wish to lockout or omit a single channel or channels
from a particular bank whilst scanning.

                          EXAMPLE To pass (lockout) channel 013 when
scanning.

1. Press 1 3 +  Press MR (If the channel not already displayed) 3. Press
FUNC 4. Press PASS

    Any channel that is passed in Memory scanning can be recalled in
Memory mode.

The small "ch" after the memory channel will now flash indicating that
during scanning the unit will "pass" this channel. The channel can still
be recalled by manually in memory mode.

You can also pass a channel in memory scan by pressing FUNC + PASS
during a transmission, next time round this channel will not be
monitored.


If all the channels in the bank or banks selected to be scanned have
been passed then ALL PASS will be displayed when the SCAN key is
pressed.


                  CANCELLING CHANNEL PASS =======================

To cancel Memory channel pass simply recall the particular channel and
press FUNC+PASS again. The small "ch" after the channel number will stop
flashingg. Caution. For those of us who can't read the screen, this
option should be used with care. For once it is in pass-memory, it will
be difficult to determine which channels have been passed over. The only
way round it is to pass all the channels in a bank, and unpass them.
With a hundred channels in each bank, this becomes a tedious task.



                        PROGRAM SCAN ============

A useful facility on the MVT-7100 has been provided so that you can
program the set to scan any 10 individual channels from each bank. Up to
100 different channels can be scanned (no more than 10 from any one bank
though) without having to lockout or Pass numerous other channels that
you may not wish to scan.

So for example, if you put channels 5, 122, 145, 166, 255, 367, 389,
399, 499, 501, 523, 822, 823, 868, 976, & 999 into the Program Scan
memory each time you pressed FUNC + P-SCAN all these memory channels
would be scanned. You can also just scan a single bank or any number of
banks just like "normal" scanning.

You can enter a maximum of 10 channels per bank into the Program Scan.
If you enter any more than 10 you start to replace the first one, then
second and so forth.

The number of channels selected from the current bank will be shown
briefly at the top right of the display each time you enter a channel to
the Program Scan.


                          EXAMPLE To enter channel 5 into the Program
Scan Memory

          1. Press 5 +  MR (To recall channel 5) 3. Press FUNC + PGM
Program scan key is func plus 6.

The letters PGM will be displayed and flash when any channel that has
been entered into the Program Scan is recalled.

                          EXAMPLE To scan all the channels in Program
Scan

                  1. Press FUNC +  P-SCAN Function key plus 9.


PGM-SCAN will be displayed together with the banks being scanned. When a
transmission is received the bank number in which the channel is located
will flash.


                          EXAMPLE To scan only the Program Scan channels
in Banks 9 & 0

                        1. Press 9 0 2. Press FUNC +  P-SCAN function
key 9

PGM-SCAN will be displayed together with the banks being scanned, in
this case just 9 & 0. When a transmission is received the bank number in
which the channel is located will flash.

If the bank or banks selected for Program Scan have no Program Scan
memory channels entered "Error" will be displayed sounding a double beep
followed by a lower tone.




            REMOVING CHANNELS FROM PROGRAM SCAN
===================================

To cancel a channel from the Program Scan memory you recall the memory
channel and repeat the same procedure as above except that this time the
letters PGM will disappear and the channel will then no longer be in the
Program Scan memory.

                          EXAMPLE To cancel channel 5 from the Program
Scan Memory

1. Press 5 +  MR (To recall channel 5 - PGM will be flashing) 3. Press
FUNC + PGM (func 6 (PGM will no longer be displayed) Again this will
provide a slight problem for those of us who can't read the screen. An
alternative approach is to delete the entire program-scan bank. Then,
you can start over. To do this, select program-scan by func 9. Then keep
entering pgm by func 6 until an error beep is heard. This will drop you
out of program scan automatically.

                         MODE SCAN =========

Another little useful scanning mode provided on the MVT-7100 is Mode
Scan. If for example  you wanted to Scan all the channels that had been
programmed in FM you would select "FM" mode in Manual mode and press
FUNC + M-SCAN. You would then scan any memory channels that contained
frequencies in FM mode.

This can be particularly useful, if for example you wanted to scan all
your airband frequencies (which would be in AM,  if they are not they
should be !) but they were spread between several different banks.
Rather than have to mess around with passing channels or selecting only
certain banks to scan it is a simple case of selecting AM on any
frequency in manual mode then FUNC + M-SCAN. Hey Presto you now are now
scanning only frequencies in AM.

As with "normal" Scan and Program Scan channel pass can be used and you
can specify a single bank or up to 4 different banks in Mode Scan. So if
you only wanted to scan those frequencies in FM in Banks 4 & 7 you would
select FM on any frequency in manual mode, then press 4, 7, FUNC,
M-SCAN.



                          EXAMPLE To scan only those frequencies stored
in WFM mode

1. You must be in manual mode, any frequency will do in WFM 2. Press
FUNC + M-SCAN



When in Mode Scan SCAN will be displayed together with the selected mode
which will be flashing. When a transmission is received the bank number
in which the channel is located will flash. PGM will flash with any
channel that has been included in the Program Scan as well.


  To return to normal Scan mode simply press the SCAN key. To return to
memory mode press either FUNC + M-SCAN again or just the MR key. Key in
a memory channel followed by MR when scanning and you will go direct to
the chosen channel.

If you wish to return to Manual mode when in Mode Scan press the MR key
twice.



                         SEARCHING =========

To start storing frequencies into memory channels assumes that we
already know what frequencies we want to listen to either through
previous experience or via one of the many publications now available.
If you wish to try and locate new active frequencies within certain
parts of the radio spectrum the MVT-7100 has a Search facility which
will allow us to rapidly "search", in any mode or increment step up or
down from a displayed frequency or alternatively between two
frequencies. To start the MVT-7100 searching up from a displayed
frequency just press the SEARCH key, the MVT-7100 will ultimately work
its way to 1650MHz. By rotating the tuning knob or pressing the *
direction arrow you can reverse the search direction to go 'backwards'
all the way to 530KHz. An undocumented feature of search is browse. If
you don't press the search key after entering a frequency, you can open
the squelch so that you hear the noise in the receiver. Then, press
either the up or down arrow keys (lower left corner, and one above), and
the set will begin to move up the band. This gives you a rapid means of
scanning the segment with an open squelch. This gives some of us
old-timers who are used to "tuning" a radio a similar feel to this
process. Sometimes, this will give you a feel for where signals are. In
single-sideband mode, this feature is most important. Let's suppose you
are tuning through the amateur radio spectrum. Most signals there are
single side band. The process for hearing these signals, and resolving
the Donald Duck (tm) like sound is as follows. Let's suppose you are
listening to the 75 meter phone band. This begins in the United States
at 3.750mhz. You punch this frequency into the scanner till it displays
on the display. Then, you press func followed by mode which is 3 keys up
from func. You then select lower side band (the offset for 75 meter, and
40 meter phone), and enter. You are now ready to scan up the band,
looking for signals. The radio will not scan ssb very well. So, you must
open the squelch by turning it counter-clock-wise.Press the up-arrow
key, and listen to the signals pass. You will hear a rising, and falling
sound as you pass through numbers of carriers, and signals. As you come
to the voices of amateurs talking to each other, you will be able to
resolve them by rocking the arrow controls, till the signal becomes
intelligible. This takes a fair bit of skill if you haven't done this
before. An example of traditional search procedure.

                          EXAMPLE The displayed frequency, in manual
mode is 903.1375, FM, 12.5KHz steps. Press SEARCH to start searching
upwards from the displayed frequency.



If you wish to change the reception mode or increment steps you may do
so while the set is searching following the instructions earlier on page
13.


                PRE-PROGRAMMED SEARCH BANKS ===========================

The MVT-7100 has been pre-programmed at the factory with the following
10 search banks which are in most cases unsuitable for the U.K.
listener.

Search Band   Start Freq   Stop Freq       Step Size     Mode

Bank  1           76.00 -  107.75MHz    50KHz Steps     WFM Bank  2
108.00  -  142.00MHz    50KHz Steps     AM Bank  3         144.00  -
146.00MHz    20KHz Steps     NFM Bank  4         146.00  -  154.65MHz
10KHz Steps     NFM Bank  5         156.00  -  162.05MHz    12.5KHz
Steps   NFM Bank  6         175.75  -  221.75MHz    50KHz Steps     WFM
Bank  7         430.00  -  440.00MHz    20KHz Steps     NFM Bank  8
450.0125-  451.50MHz    12.5KHz Steps   NFM Bank  9         850.025 -
859.9875MHz  6.25KHz Steps   NFM Bank 10         903.0375-  904.9875MHz
12.5KHZ Steps   NFM

To start searching a particular bank simply press the bank number
followed by SEARCH. EXAMPLE To search Bank 0 1. Press 0 (0 will flash)
2. Press SEARCH The set will now start searching from 903.0375MHz to
904.9875MHz stopping on any active frequencies. The 0 at the top right
of the display indicated Bank 0 is being searched.


                          EXAMPLE To search Bank 9, between 850.025MHz
and 859.9875MHz, FM, 6.25KHz steps. 1. Press 9 2. Press SEARCH



             PROGRAMMING NEW SEARCH BAND LIMITS
==================================

Whilst the pre-programmed bands may be a great interest to Fred Bloggs
living in downtown Tokyo they are of little use to you Fred Bloggs of
downtown U.K.

To make the best use of the search banks we need to re-program them with
frequencies of your own interests.  Try and keep the limits to just a
few MHz as to increase the chance of receiving previously unheard
transmissions. Just do a few MHz at a time as it will prove far more
productive than trying to do the whole lot in one !

To program search limits is a relatively simple operation (!!), all we
need to do is enter the start and end frequencies into one of the 10
search bands.

If you want to set the Mode and Increment steps that you wish to Search
in you can do so in Manual mode before you re-program any banks. You can
however change the Mode and Increment steps of any Search Bank while
searching.

                          EXAMPLE To program search Bank 6 to start at
422.20MHz & finish at 422.30MHz

1. Ensure you are in manual mode and not searching or scanning 2. Press
FUNC + BW (The key immediately above func. The display will now flash
and the scanner beep twice) 3. Press 4 2 2 . 2  (The bottom limit/the
frequency we wish to start at. Scanner will beep once, pause and beep
again.) 4. Press ENT The scanner will beep once, pause, and beep the
same pitch once again. That's how you can verify you are in the right
mode.

5. Press 4 2 2 . 3 (The top limit/the frequency we wish to finish at) 6.
Press ENT Scanner will beep once, pause, and beep again. 7. Press 6
(this is the bank we will store these limits in) 8. Press ENT (If the
"beep" is still on a double beep will sound to indicate the above has
been accepted the display will return to the previous frequency in
manual mode)


You have now re-programmed bank 6. When you now press 6 + SEARCH your
set will search between 422.20MHz & 422.30MHz in Narrow FM and 12.5KHz
increment steps.


                          EXAMPLE To program search Bank 2 to start at
324.20MHz & finish at 330.00MHz

1. Ensure you are in manual mode and not searching or scanning 2. Press
FUNC + BW (The display will now flash and the scanner beep twice) 3.
Press 3 2 4 . 2  (The bottom limit/the frequency we wish to start at) 4.
Press ENT 5. Press 3 3 0 (The top limit/the frequency we wish to finish
at) 6. Press ENT 7. Press 2 (this is the bank we will store these limits
in) 8. Press ENT



DON'T FORGET if you want to change the mode or increment steps you can
do so when the set is searching by simply by pressing FUNC + MODE then
rotating the rotary knob and pressing ENT or to change the steps just
press the STEP and rotate the tuning knob then press ENT

The same procedure should be used for re-programming any of the other
bands with frequency limits of your choice but remember keeping the
limits to just a few MHz (no more than say 10MHz) will greatly increase
the chances of locating previously unheard active frequencies.



         STORING FREQUENCIES IN MEMORY FROM SEARCH
=========================================

You can store frequencies found during Search direct into any one of the
1000 memory channels by pressing FUNC + MW whilst the set remains on a
transmission. The frequency on the display will be transferred into
memory.

If no channel is specified the frequency will be transferred into the
last memory channel recalled. If you wish to store the frequency in a
specific memory channel key in the memory channel then FUNC + MW.

                          EXAMPLE The set searching from 230.00MHz
upwards and stops on 236.80MHz, you wish to store this in a memory
channel.

   1. Press FUNC + MW while the set is on that frequency




Memory channel 14 was the last channel recalled so 236.80MHz will now be
stored in that channel replacing the existing frequency.  If you wish to
store any further frequencies into  subsequent channels each press of
FUNC + MW will store the frequencies in channels 15, 16, 17 and so
forth.


                          EXAMPLE The set searching from 230.00MHz
upwards and stops on 236.80MHz, you wish to store this in memory channel
134.

                       1. Press 1 3 4 2. Press FUNC + MW while the set
is on that frequency


                     SEARCH PASS MEMORY ===================

When searching it is possible to program the MVT-7100 to pass those
frequencies which always cause the receiver to stop. These frequencies
may be local interference, data signals or maybe just frequencies you do
not wish to monitor.

Up to 500 different frequencies can be entered into the Search Pass
Memory, any frequency that is stored in this memory will not be
monitored when the unit is searching. If you try and enter more than 500
frequencies in the Search Pass Memory "FULL" will be displayed and you
will have to remove some frequencies before others can be added. Any
frequencies stored in the Search Pass Memory can still be recalled in
Manual, Memory or Scan mode.

If you know of any frequencies you wish to enter into the Search Pass
Memory, enter them in Manual mode then press FUNC + PASS. (bottom-key
second from left) The display will temporally show a "P" on the left
before returning to manual mode and beep.

If when searching the MVT-7100 stops on a signal you do not wish to
monitor in future press FUNC + PASS while on that particular frequency,
the display will temporally show "P" then resume searching.

                          EXAMPLE To store 128.80 into the Search Pass
Memory.

                   1. Press 128.80 + ENT 2. Press FUNC + PASS (bottom
row, second from left) A "P" appears on the left of the display then the
unit returns to manual mode scanner beeps once.

                          EXAMPLE To store 353.20 into the Search Pass
Memory during Search

2. Press FUNC + PASS (when stopped on the desired frequency) A "P"
appears on the left of the display then the units continues searching
This frequency will now be skipped on subsequent automated searches.



        CHECKING CONTENTS OF THE SEARCH PASS MEMORY
===========================================

If you wish to check the contents of the Search Pass Memory you must be
in Manual mode then press FUNC + SPR. (key directly above mpas 2 rows up
second from left) The scanner gives a beep when this mode is accessed.
Remember the spr key is shared with the 0. Another way to confirm access
of this function is to press one of the keys in the numeric display.
I.E. 1, or 2. They will be deactivates.

The "P" shown to the left of the display will be flashing when recalling
frequencies stored in Search Pass Memory. The first frequency to be
displayed will be the one nearest the frequency shown in Manual Mode
just before you pressed FUNC + SPR.  If no frequencies are in the Search
Pass Memory then "Error" will be displayed. A useful trick is to type in
a frequency near where you want to be in search-pass memory. That is, if
you are looking for frequencies stored between 330, and 345, in manual
mode enter a frequency say 330.25, and enter search-pass memory as
described above. You will then be presented with the frequencies in this
area.

By using the Rotary dial or direction arrows you can scroll through
those frequencies stored in the Search Pass Memory. If only one
frequency is stored in the Search Pass Memory then the display will not
alter.

To return to Manual mode either press FUNC + SPR again or the C/AC key
once.


        REMOVING FREQUENCIES FROM SEARCH PASS MEMORY
=============================================

If you wish to remove any frequencies from the Search Pass Memory and
therefore monitor them again when searching you must recall the
frequency as described above, and when the frequency is displayed press
FUNC + PASS. The display will then show the next frequency in the Search
Pass Memory.


                          EXAMPLE To remove 13.270MHz from the Search
Pass memory

               1. You must be in Manual Mode 2. Press FUNC + SPR 3.
Using the rotary dial or direction arrows to select 13.270MHz 4. Press
FUNC + PASS


If you remove the last frequency from the Search Pass Memory you will
automatically return to Manual Mode. To return to Manual mode either
press FUNC + SPR again or the C/AC key once.

Another useful trick is to check whether a new frequency you have just
heard is already in scan memory. With 1000+ channels available, no easy
task. Let's suppose you have been storing all of your memory channels in
pass-memory. This is to ensure you don't encounter them again on new
searches. You hear a new frequency but aren't sure it is already in
memory. Enter pass-memory. If this frequency has been already dumped, it
will display since it is the nearest to the frequency from which you
entered.

                          Example.

       Lets suppose you are monitoring vhf aviation. The controller has
just directed an aircraft to 128.5mhz. You don't know if you already
have this frequency in memory. Type 128.5 into manual memory by typing
the frequency followed by enter. Then go into pass-memory by typing
func. plus mpas. If the frequency is displayed you will know that it's
likely you already have this frequency in memory.



                         ATTENUATOR ==========

Turning the attenuator on will not only help reduce the strength of
interference but may stop the reception of weak signals as well.

When strong signals are present on certain frequencies some interference
may occur. To reduce the signal strength of strong signals the
Attenuator should be switched on. To turn the attenuator on press FUNC +
ATT. When the attenuator is on ATT will be shown in the display. In
memory mode the Attenuator must be set for individual channels. In
Search or Manual mode the Attenuator will be on for all frequencies. To
turn the attenuator off press FUNC + ATT again.

     The Attenuation is approximately -15dB (at 108MHz) In some cases,
this key provides an audible clue as to its result. The back ground
noise in the radio will diminish when this key is used.

 The attenuator has a global function when in search mode. That is, if
you are searching a pre-set. pattern of frequencies, you will attenuate
the entire search. Thus, every channel you enter into memory for future
scanning will be attenuated, unless you change it after the fact.

                           DELAY =====

After a transmission has finished the MVT-7100 will continue to Scan or
Search after approximately 2 seconds. If you wish the resumption to be a
little longer to perhaps allow for a delayed reply then by pressing FUNC
+ DELAY there will be a 4 second delay.

When the Delay facility is on DELAY will be displayed. To cancel the
Delay facility press FUNC + DELAY again.

   Delay is also a global feature. It affects the entire scanner holding
of frequencies.


                            SKIP ====

During Scan and Search the MVT-7100 will remain on a frequency for the
duration of the transmission, with the Skip facility on scanning or
searching will continue after 5 seconds of stopping on a frequency. To
turn Skip on press FUNC + SKIP. With skip on SKIP will be displayed. To
turn the skip facility off press FUNC+SKIP again.

  Skip is also a global feature. All frequencies in either search or
scan are affected.

                            BEEP ====

With the beep sound on BEEP will show in the display. To turn the beep
sound off press FUNC + BEEP. With the beep sound off press FUNC + BEEP
to turn it back on again

               There are 3 types of "Beep" !

   1 - A single Beep is heard each time a key is pressed. 2 - A double
Beep is heard when you store and erase information. 3 - 3 Three Beeps
(the latter two slightly higher in tone) indicate and Error.




                        BATTERY SAVE ============

By turning the Battery Save facility on you can put the MVT-7100 into
several states of standby mode, this will reduce consumption.

The Save facility will only work when in Manual or Memory Channel Recall
mode.  There are 3 Save Modes:- SAVE MODE       PERIOD OF NON OPERATION
1             0.3 seconds 2             0.9 seconds 3             1.5
seconds

When the Save facility is turned on and there is no activity on the
selected frequency for 5 seconds after the end of a transmission the
MVT-7100 will enter the selected Save mode and monitor the displayed
frequency for 0.3 of a second. If for example Save Mode 1 was selected,
the MVT-7100 would monitor the displayed frequency every 0.3 seconds for
0.3 of a second, if Save Mode 3 was selected the frequency would be
monitored every 1.5 seconds for 0.3 of a second.

When a signal is detected the MVT-7100 will "turn itself on" for the
duration of the transmission then return to Save mode after 5 seconds of
non activity.

                 Does all that make sense ?

                          EXAMPLE To Set Battery Save Mode 3

1. Select chosen frequency either in Manual or Memory recall Mode 2.
Press 3 3. Press FUNC + SAVE



The unit will stay in Save mode whilst remaining in Manual or Memory
recall mode even if you turn the set off and back on again. To cancel
Battery  Save press FUNC + SAVE.

If you start the set scanning or searching Battery Save will be
cancelled automatically.
