DC POWER CONNECTION
The TX4400 is designed for 13 .8 Volt DC, negative earth
installations only (i .e . where the negative terminal of the
battery is connected to the chassis or frame of the vehicle) .
There are two recommended methods of installation .
Radio remains on when the ignition switch is off
Connect the radio's negative (black) lead to the vehicle's
chassis, or if preferred, directly to the battery's
negative terminal .
The radio's positive (red) lead should be connected via the
2 Amp fuse to the battery's positive terminal . Alternatively,
the positive lead could be connected into the fuse box
at a point that has +13 .8 Volts continuously available
(preferably the battery side of the ignition switch) via the
2 Amp fuse .
Radio turns off with the ignition switch
Connect the radio's negative (black) lead to the vehicle's
chassis, or if preferred, directly to the battery's
negative terminal .
The radio's positive (red) lead should connect to an
accessory point via the 2 Amp fuse in the vehicle's fuse box .
This point should supply +13 .8 Volts only when the ignition
switch is turned ON or in the ACCESSORY position .
Refer to above diagram .

HIGH VOLTAGE WARNING
The TX4400 has a built-in, high voltage detection system to
warn you if an over voltage situation occurs .
If the power supply voltage exceeds 18 Volts DC, the
channel display will flash 'hi dc' for 5 seconds when the
unit is first turned on, or at the time the voltage exceeds
18 Volts . In addition, when transmitting, the TX indicator
will flash and the transmitter will select low output power .
If the over voltage warning appears you should switch your
TX4400 off and disconnect it from the power source, before
locating the cause of the trouble .
Once the High Voltage warning has been triggered, and
you have fixed the source of the problem, you will need to
switch the TX4400 OFF then ON again to reset it .
The power source must not exceed 30 Volts .
ANTENNA CONNECTION
GME supply a wide range of mobile and base station
antennas designed specifically for UHF
CB communications .
The antennas are fitted with a PL259 coaxial plug suitable
for connection to the antenna socket on the rear panel of
the radio .
Never transmit without an antenna connected otherwise
damage to the radio may result .
