USINg SCAN
• If a busy channel is found, scanning will pause on that channel
to allow the signal to be heard and will remain there for as long
as the channel remains busy. once the channel has been clear
for 5 seconds, scanning will resume automatically.
• If your radio is paused on a busy channel and you wish to
remain there, briefly press the
mode and remain on the busy channel.
• If the radio pauses on a busy channel and you don't wish to
listen to the conversation briefly press either of the
keys. the radio will skip over that channel and resume scanning
from the next channel in the sequence.
TRANSMITTINg WhILE SCANNINg
When scanning, your radio remembers the last channel on which it
transmitted and will automatically return to that channel each time
the Ptt is pressed.
Before scanning, you can define your initial transmit channel by
preselecting that channel first before you press the
scanning has commenced, pressing the Ptt will pause the scan
and your radio will transmit on the preselected channel. If there is
no activity on the channel after 5 seconds the scan resumes.
• If scanning pauses on a (different) busy channel and you press
the Ptt during this time, the busy channel becomes your new
default transmit channel. If there is no activity on the channel
after 5 seconds the scan resumes but subsequent presses of
the Ptt will return you to this new channel. this allows you to
continue to use this channel even if pauses in the conversation
exceed the 5 second timeout period.

iNsTAllATioN
the tX3100 is supplied with a slim, U-shaped mounting cradle. the
cradle can be screwed or bolted in any convenient location in your
vehicle (under or above the dash, on the centre console, etc.) using
the mounting slots provided in the cradle. the tX3100 contains
a built-in speaker and should be installed in a location where the
sound can be heard from the driver's position. Alternatively it can
be installed in a less audible location and an extension speaker
used instead.
the microphone comes complete with a mounting clip. Its light
weight design allows it to be mounted in almost any convenient
position accessible to the driver.
When installing the radio, avoid mounting it close to heaters or air
conditioners. Screw the microphone's clip to a firm surface. Fit the
tX3100 into the cradle and tighten the gimbal knobs. Place the
microphone in its mounting clip. Finally, plug the microphone into
the front panel of the tX3100 and the power and antenna leads
into the sockets provided on the rear of the radio.
ANTENNA INSTALLATION
It is essential to select a good quality, high efficiency, 477 MHz
antenna. A poor quality antenna or one not designed for the
specific frequency band you are using will give very
poor performance.
GME have a wide range of suitable 477 MHz UHF CB antennas to
suit most installations and applications. We recommend contacting
your local GME retailer for advice.
Connect the antenna cable to the rear antenna socket using a
PL259 coaxial connector.
NOISE SUppRESSION
the inherent design of FM transceivers result in a high level of
resistance to ignition and electrical interference. However in some
installations it may be necessary to take additional steps to help
reduce or eliminate noise interference. During installation, try to
route the DC battery leads, the antenna lead or any accessory wires
away from the engine compartment, ignition or alternator wiring.
If the noise continues, it may be necessary to fit a suppression kit
