OPERATION – GENERAL FUNCTIONS
VOLUME ON/OFF
Rotate the volume control clockwise past the ‘Click’ to turn
the TX2700 ON. Continue to advance the control clockwise to
increase the volume. Rotate the control counter-clockwise to
turn the radio off.
NOTE: At minimum volume setting there is still suffi cient
volume to be heard in a quiet cabin environment.
SQUELCH CONTROL
The Squelch control is used to eliminate the background noise
when there are no signals present. To adjust the Squelch, fi rst
rotate it fully counter-clockwise until the background noise
is heard, then slowly rotate it clockwise until the noise just
disappears. If there are signals on the channel, you should
wait until the channel is clear before adjusting the Squelch (or
select a quiet channel).
Once adjusted, the receiver will remain quiet as long as
there are no signals present, but an incoming signal will
override the Squelch and be heard in the speaker. As the
control is advanced further clockwise the Squelch threshold
is progressively increased and stronger incoming signals
are needed to override it. To receive very weak signals or to
disable the Squelch, simply turn the control fully counter-
clockwise.
CHANNEL SELECTION
Select the required channel by briefl y pressing the or
keys. The selected channel is displayed on the LCD display.
Press and hold either key to quickly advance upwards or
downwards through the channels. Release the key when the
required channel is displayed or:
Select the required channel via the Rotary ‘Channel
Selector’. The selected channel number is displayed on the LCD.
DISPLAY BRIGHTNESS
The LCD has two brightness levels to provide suitable lighting
for day or night use. The default setting is bright.
The desired brightness level can be selected via the ‘Dim’
switch located on the front panel.
TRANSMITTING
To transmit, press the PTT button on the microphone. Hold
the microphone 2-6 cm from your mouth and slightly to
one side so your voice does not project directly into the
microphone. Speak at a normal voice level. Your TX2700 has
a built-in speech processor which automatically controls the
level of your transmitted voice. It is not necessary to raise your
voice or shout into the microphone.
NOISE LIMITER
The NL key activates an extremely effective noise limiter
circuit which helps to eliminate most electrical impulse inter-
ference caused by engine ignition systems etc. This
allows clearer reception of weak signals even under noisy
electrical conditions.
When the NL key is selected, ‘NL’ is displayed on the LCD.
SCANNING
The TX2700 is fi tted with a Scan function that allows a
group of user selected channels to be scanned for activity.
Your TX2700 has a Scan memory which remembers which
channels you would like to Scan. By default your TX2700 is
supplied with all channels in the Scan memory.
To see which channels are presently in the
Scan memory
Select each channel one by one using the or key or ro-
tary selector and check to see if ‘M’ is displayed to the lower
right of the channel number.
If ‘M’ is displayed, the channel is in the Scan memory.
To Add or Remove a channel from the Scan memory
Select the required channel, then press and hold the SCAN
key until a beep is heard. If ‘M’ appears to the lower right of
the channel number, the channel has been added to the Scan
memory, otherwise it has been removed.
To Scan
Adjust the Squelch control so the radio is quiet, then briefl y
press the SCAN key. A high beep will be heard, ‘SCAN’ will
appear in the display and the channel numbers will change
rapidly as the radio begins scanning. If a signal is found, the
radio will pause on that channel and will remain there as long
as the channel remains busy. Once the channel has been clear
for 5 seconds, scanning will resume.
NOTE: You must have at least two channels programmed into
the Scan memory otherwise the radio won’t scan.
To change the Scan direction
Press the or key. The radio will scan in the direction of
the selected channel key.

PAGE 6 INSTRUCTION MANUAL TX2700
To skip over a busy channel and resume scanning:
Briefl y press the or key. Scanning will resume.
To transmit on a busy channel:
Wait for a break in the conversation, then press the PTT
switch. The radio will exit the Scan mode and stay on the
channel allowing you to communicate with others on
that channel.
To resume scanning briefl y press the SCAN key again.
NOTE: If the PTT is pressed while the radio is scanning, it
will be ignored and a low beep will be heard when the PTT
is released.
To exit the Scan mode manually:
Briefl y press the SCAN key. ‘SCAN’ will disappear from
the display.
NOTE: Excessive noise on a channel can cause the scanning
to pause on that channel even if there is no signal there. If
this only happens on one channel, you may need to remove
that channel from the scan memory. If it happens on all
channels, you should try increasing the squelch setting.
OPERATION – CB MODE
PRIORITY CHANNEL
The Priority channel is preset to channel 8 allowing it to be
instantly recalled at the press of a key.
To use the Priority channel
Simply press the Priority key at any time. The radio will jump
straight to channel 8. If ‘Scan’ or ‘DW’ was selected, they will
be cancelled.
To return to the previously selected channel
Press the Priority key again.
DUAL WATCH
Dual Watch in CB mode allows your TX2700 to monitor both
the Priority channel and another selected channel by quickly
switching between them. Any signals received on the Priority
channel take precedence over signals on the selected channel.
To use the Dual Watch feature, adjust the Squelch control so
the radio is quiet, select your preferred channel using the
or keys or rotary selector then press the DW key. ‘DW’ will
appear on the display and the channel display will alternate
between your selected channel and the Priority channel.
If a signal is received on your selected channel, the radio
will pause on that channel but will continue to switch to the
Priority channel every 2 seconds and a brief interruption
to the signal will be noticed. Once the signal has gone, normal
Dual Watch switching will resume.
If a signal appears on the Priority channel at any time, the
radio will stop switching and will remain on the Priority
channel for as long as the signal is present. Once the signal
has gone, normal Dual Watch switching will resume.
NOTE: If you press the PTT switch while Dual Watch is
selected, your TX2700 will transmit on the selected channel.
If you wish to talk on the Priority channel, press the Priority
key to cancel the Dual Watch and switch straight to the
Priority channel.

INSTALLATION
LOCATION
It is advisable to spend a little time selecting the best location
for your TX2700. The mounting bracket can be rotated above,
below or behind the radio enabling the radio to be mounted
in a wide range of locations. In addition, an optional fl ush
mounting kit allows the radio to be fl ush mounted in a panel
or dashboard.
When choosing a location:
• Select a location that won’t expose your radio to
continuous direct sunlight which could cause overheating.
• Ensure the location allows a free fl ow of air around the
heat sink on the back of the radio.
• The microphone and all controls should be readily
accessible and the loud speaker easily heard from the
normal driving position. An extension speaker can be
installed if required.
• Electronic interference caused by other electronic devices is
best minimized by mounting your TX2700 at least 300 mm
from such devices, including all wiring and cables.
INSTALLING THE UNIT
After choosing a location, hold the unit with the mounting
bracket attached, to the desired position and mark the
location with a pencil. Remove the mounting bracket from
the radio and drill the mounting holes. Bolt or screw the
bracket in place using hardware suitable for the mounting
surface. The unit is supplied with steel screws, however, if the
mounting surface is unsuitable for screws you may need to
replace these with bolts. Remember the fi xings for overhead
mounted units may have to withstand being driven on
unsealed roads.
The TX2700 mounting bracket is designed with a unique dual
position gimbal mounting slot. This design not only allows
the TX2700 to be tilted over a much greater range, but also
provides a slim, low profi le mounting position for installations
where space is very limited.
Flush Mounting –
(Optional MK200B fl ush
mounting kit available)
DC CONNECTIONS
Connect the RED power lead to the positive (+) side of the
battery or to an accessory point in the vehicle’s fuse box.
Connect the BLACK power lead to the negative (-) side of the
battery or to a ground point in your vehicle.
NOTE: The DC Connector is not waterproof. If installed in
an exposed location, the connector should be protected with
waterproof tape to prevent water ingress.
IMPORTANT: The RED power lead is fi tted with a 2 Amp
fuse. If the fuse blows, use only a standard 2 Amp (3AG) fuse
as a replacement. Use of a higher rated fuse or a slow-blow
type could result in damage to your radio which would void
the warranty.
If required, an extension speaker may be installed to improve
sound levels in noisy environments or in locations further
away from the driving position. For locations exposed to wa-
ter we recommend the SPK45B which will fi t to the supplied
adaptor that connects to the extension speaker socket on the
rear of the radio.

ANTENNA INSTALLATION
It is essential to select a good quality, high effi ciency,
27 MHz antenna. A poor quality antenna or one not designed
for the specifi c frequency band you are using
will give very poor performance.

TX2700 INSTRUCTION MANUAL PAGE 9
GME have a large range of suitable 27 MHz CB antennas to
suit most installations and applications. We recommend you
contact your local GME dealer for advice.
Connect the antenna cable to the rear antenna socket using a
PL259 coaxial connector.
NOISE SUPPRESSION
27 MHz CB radio can be prone to electrical and ignition
interference. The reason is that electrical noise is a form
of AM transmission similar to that used by your radio and
your radio’s receiver is very sensitive. In most cases, ignition
noise can be greatly reduced or eliminated by selecting the
Noise Limiter (NL) key on the radio. In some severe cases,
additional suppression may need to be fi tted to the ignition
system of your vehicle, in which case we recommend you
consult an Auto Electrician for advice specifi c to
your installation.
FITTING THE MICROPHONE
The microphone uses a miniature 6 pin telephone style plug
and socket.
Fitting microphone to the front panel
1. Position the microphone plug so the plastic tab faces
sideways to the left on the front panel. Press the plug into
the socket until it ‘clicks’.
2. Gently press the rubber strain relief into the hole
surrounding the socket so that the slot around the strain
relief fi ts neatly inside the lip of the hole.
Fitting microphone to the rear panel
1. Position the microphone plug so the plastic tab faces
upwards on the rear panel. Press the plug into the socket
until it ‘clicks’.
2. Gently press the rubber strain relief into the hole
surrounding the socket so that the slot around the strain
relief fi ts neatly inside the lip of the hole.
Removing the microphone
1. Squeeze the rubber strain relief near the front panel to
disengage the slot, and slide the strain relief back along
the microphone cord.
2. Press the small plastic tab on the microphone plug
towards the plug to unlock it, while gently pulling the plug
outwards. If the plug does not come out easily, the tab has
not released correctly and should be pressed again. You
may need a small bladed screwdriver for this task, as the
tab can be diffi cult to reach with your fi ngers.
If required, replacement microphones are available with plug
and rubber boot already fi tted.
Rear Microphone Connection
The TX2700 also has a rear microphone connection. To use
this facility, remove the rubber grommet on the rear of the
radio and insert into the front panel of the radio. Insert the
microphone plug into rear microphone connection.
Microphone Extension Lead
The LEM6P is a 4 metre microphone extension lead that can
be fi tted to the microphone socket.
