INTRODUCTION

The TX7200 is a rugged, easy to operate, full featured
commercial hand-held transceiver operating in the
450–520 MHz UHF band. The TX7200 assembly is a very
strong structure with a single diecast frame housed in a
polycarbonate alloy case.

The range of a UHF FM signal is usually considered 'line-of­sight'. Generally the range of your TX7200 radio will vary

according to your location and the height of your antenna.
UHF signals are easily blocked by hills or large buildings
so you won’t get as much range in a valley or built-up city
areas as you will from a hilltop or in open country. If you are
having trouble contacting someone, try moving to an open
space or a higher location. Typical portable range is around
3 to 5 km depending on the terrain. Moving to a higher
location or using a repeater could extend its range.

To Remove Battery Pack To Refit Battery Pack

Slide upwards

Swing away

Press Press

Your TX7200 is supplied with a 7.2 Volt 1200 mAh Ni-MH
rechargeable battery pack. When the battery is new, it must
be fully charged before being used for the first time. If left
unused your TX7200’s battery pack will discharge itself
within a few months. If you have not used your TX7200
for some time, you will need to recharge the battery pack
before use.

The battery pack is a sealed unit. There are no user
serviceable parts inside.

WARNING:

Use only GME Electrophone approved battery
packs and chargers. The use of other types may be
dangerous and will void the warranty.

Removing the Battery Pack

The battery pack is a self contained unit which can be
removed from the radio as follows:

1. Hold the radio face down in one hand.

2. With the thumb of one hand, push the locking tab

upwards towards the top of the radio while swinging the
top half of the battery pack away from the radio with the
other hand.

3. Once clear of the locking tab, lift the battery upwards
away from the radio. The base of the battery pack is
retained in a slot in the metal frame at the base of
the radio.

Re-fitting the Battery Pack

1. Carefully position the tongue in the base of the battery
pack into the slot in the metal frame at the base of
the radio.

2. Swing the top half of the battery pack into place against
the radio.

3. Using both thumbs (one each side of the belt clip) press
the top half of the battery firmly onto the radio until the
locking tab clicks downward locking the battery pack
into place.

Charging the Battery Pack

Your TX7200 should be charged using the BCD001 Rapid
Charger. The BCD001 rapid charger can recharge the
battery pack in around 1 hour. For further information on
charging your battery and tips on conserving battery power,
see section on 'Maintaining Your Battery Pack' on page 6.

CONTROLS AND FUNCTIONS

Turning the TX7200 on or off

Rotate the volume control clockwise past the 'click' to turn
the TX7200 on. Rotate the control fully counter clockwise
past the click to turn the radio off.

Adjusting the receiver volume

While receiving a signal, rotate the volume control to
achieve a comfortable listening level. If there are no signals
present, press the Squelch key briefly (if available) to open
the squelch, then adjust the volume while listening to the
receiver's background noise. When finished, briefly press
the Squelch key again to return the receiver to the
quiet state.

Note:

The minimum setting of the volume control has been
factory preset so that, even with the volume turned right
down, you can still safely listen to an incoming signal with
your ear against the speaker (telephone style).

Selecting Channels

To change channels, briefly press the key to step up one
channel or the key to step down one channel. Holding
either or will cause the radio to step
through the channels automatically at a faster
rate. The 125 available

channels are numbered

1 - 99, A0 - A9, B0 - B9 and C0 - C5

Alphanumeric labels

As well as identifying channels by their channel number,
channels may be programmed with a 5 character
alphanumeric label. Using labels with meaningful names
makes it much easier to identify channels. Alphanumeric
labels are pre-programmed into your radio by your dealer.

e.g. The channel you normally contact your office on
might be labelled OFFCE while a construction site channel
might be labelled SITE1. In this way you no longer need to
remember which
channel numbers
to select, you
simply select the
required channel
by its label.

Activating the Backlighting

Your TX7200’s LCD features built-in backlighting. The
backlighting is normally switched off to conserve battery
power but will switch on automatically
when any key is pressed. To switch the
backlighting on without activating any
functions, press the - key twice.

BASIC OPERATION

TX7200 Instruction Manual Page 5

Transmitting

Before transmitting, check to see if the channel is already in
use ('BUSY' will be displayed and the LED on the top of the
radio will be green). If the channel is busy, you should wait
until it is clear before transmitting.

To transmit, press the Push-To-Talk (PTT) switch on the
left-hand side of the radio. Hold the radio about 5-8 cms
from your face with the antenna vertical and speak into the
built-in microphone located just below the speaker. When
talking, speak at a normal voice level. The microphone is quite
sensitive so it is not necessary to raise your voice or shout.

Receiving

Note:

Your radio may be programmed with options that
could affect the way your radio behaves when it receives a
call from another radio.

Normal Reception

Your radio will normally be muted (squelched) so that it is
quiet when there are no signals. When a transmission is
received, the radio will automatically unmute itself to allow
you to hear the call. When receiving a signal, adjust the
volume control as desired for a comfortable listening level.

The BUSY Indicator

Whenever the channel is active, the BUSY indicator will
appear on the display and the green LED on the top of the
radio will light. However, depending on the muting options
selected on your radio, you may not always hear any sound
from the speaker. This can happen when others are sharing
the channel but their calls are not meant for you. For this
reason it is important that you visually check that the
channel is not busy before making a call to ensure you do
not accidentally talk over someone else.

PROGRAMMABLE FUNCTIONS

* Allows access to a second feature programmed into any key by first pressing the assigned Function key

The front panel keys are able to perform multiple functions
depending on how they are programmed. Since most of
these functions can be programmed into any of the front
panel keys, no specific key can be addressed as performing a
particular function. The following table can be used to mark
the specific features that may be programmed into your
radio against the front panel keys that will access them.

Your TX7200 will have been programmed by the dealer
to suit your specific requirements by enabling only those
features that are useful to your operation. Your dealer will
show you how to use those features.

Tick the boxes that match the function keys on your radio
with the specific feature programmed by your dealer.

MAINTAINING YOUR BATTERY PACK

For information on removing, fitting and recharging the
battery pack, refer to ‘GETTING STARTED’ on page 3 of
this manual.

Your TX7200 is supplied with a 7.2 Volt 1200 mAh Ni-MH
(Nickel Metal Hydride) rechargeable battery pack. When the
battery pack is new, it must be fully charged before being
used for the first time.

If left unused, your TX7200’s battery pack will discharge
itself within a few months. If you have not used your
TX7200 for some time, you will need to recharge the
battery pack before use.

The battery pack is a sealed unit. There are no user
serviceable parts inside.

WARNING:

Use only GME Electrophone approved battery
packs and chargers. The use of any other types may be
dangerous and will void any warranty.

Low Battery Indicators

When the battery voltage drops to around 6 Volts, your
TX7200 will give 6 quick beeps, BATT will flash on the
display and the Tx/Busy LED will flash ‘Orange’ to indicate
that the battery needs to be charged. You should recharge
the battery pack as soon as possible.

If you have been transmitting using the High Power setting,
you can extend the life by switching to Low transmit power.

Battery Charging

It is recommended that you charge your TX7200’s battery
using the BCD001 rapid charger. The BCD001 rapid charger
can recharge your battery pack in around 1 hour, less if
there is still some charge remaining.

Cycling your Battery Pack

Cycling of your Ni-MH battery should not be necessary.
However, for maximum performance we recommend that
you try to fully discharge the battery from time to time
before recharging it.

Battery Usage

The time taken to discharge the battery pack will depend
on how you use your TX7200. The 1200 mAh battery pack
is powerful enough for a full days use under
average conditions.

Conserving Battery Power

The TX7200 has built in power saving features to help
you get the maximum amount of time between charges
from your Ni-MH battery pack. If you need to operate
your TX7200 in a situation where you require maximum
battery life (e.g. a remote site where there is no convenient
recharging facility nearby), the following hints can greatly
reduce the amount of power drawn from the battery pack.

Sleep Mode: The TX7200 will automatically enter the
‘Sleep’ mode after around 30 seconds of inactivity (i.e. no
transmission or reception).

While sleeping, it will still check for incoming signals
but it will draw only about one fifth of the power from
the battery. As soon as a signal is received or any keys
are pressed, the TX7200 will wake up again. This sleep
function is automatic and by itself can greatly extend the
battery life in standby mode by many hours.

Quiet Mode: If ‘Quiet’ mode is selected, the TX7200
will remain ‘asleep’ on Quiet channels even if they are busy
unless your Selcall Ident is received.

Scanning: The TX7200 draws more power from the
battery when scanning than when monitoring a single
channel. This is because it must wake more often to
monitor each channel for activity. You can squeeze
that extra bit of life from the battery by avoiding any
unnecessary scanning. In addition, scanning several
channels increases the chance of finding a signal thereby
keeping the receiver awake and the squelch open
more often.

USE ONLY GME ELECTROPHONE

APPROVED CHARGERS.

USE OF OTHER TYPES MAY BE DANGEROUS

AND WILL VOID THE WARRANTY.

DO NOT CONNECT YOUR VEHICLE’S 13.8 VOLT

BATTERY SUPPLY TO THE CHARGING SOCKET

AS DAMAGE WILL RESULT.

TX7200 Instruction Manual Page 7

Low Transmit Power Setting: The transmitter
has both HIGH and LOW power settings. If you are only
operating over short distances, are in a reasonably high
location or are close to a local repeater, try using the LOW
transmit power setting. This reduces the transmitter power
from 5 Watts to 1 Watt, effectively tripling the ‘talk’
time available.

General: Continuously monitoring a busy channel will
reduce the battery life since incoming signals will keep the
receiver awake and the squelch will stay open for longer
periods of time. This will draw much more power from the
battery pack. If you are expecting to receive a Selcall on a
busy channel, program that channel for ‘Quiet’ operation
and select the Quiet mode. The TX7200 will then stay
‘asleep’ until your Selcall Ident is received.
