Dc Power Connection; Antenna Connection - GME GA9800 Instruction Manual

Dc power connection

the tX3340 is designed for 13.8 Volts 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 (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
in the vehicle's fuse box via the 2 Amp fuse. this point should
supply +13.8 Volts only when the ignition switch is turned on or in
the AccEssory position.

high Voltage warning
the tX3340 has a built-in, high voltage detection system to warn
you if an overvoltage 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 overvoltage warning appears you should switch your tX3340
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
tX3340 oFF then on again to reset it.
the power source must not exceed 25 Volts otherwise permanent
damage may occur to your radio, which may not be covered by the
manufacturer's warranty.

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
