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 huge range of suitable 477 Mhz Uhf CB
antennas to suit most installations and applications. We
recommend you contact your local Dealer for advice.
Connect to the antenna cable to the rear antenna socket
using a PL259 coaxial connector.

NOISE SUPPRESSION
The inherent design of fM transceivers results 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 in
which case we recommend you consult an auto electrician
for advice specific to your installation.
higher frequency electrical interference cause by electric
motors can be suppressed directly at the motor terminals.
DISCONNECTING THE MICROPHONE
It is recommended that the microphone be left permanently
connected to the TX4600, but if it must be disconnected,
proceed as follows:
1. Insert a small screwdriver between the rubber boot and
the lip of the raised area on the front panel.
2. Ease the rubber boot out of the cable entry hole and
slide it along the cable away from the front panel.
3. Identify the plug locking lever, work the screwdriver
blade behind it and move the lever towards the plug
body. At the same time gently pull the plug from the
socket. (see diagram below)
If required, replacement microphones are available with
plug and rubber boot already fitted.
