GME TX3400 - Manual (Page 21)

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 TX3400 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 TX3400
OFF then ON again to reset it.
If the power source exceeds 30 Volts, the
internal protection diode will cause the fuse to
blow.

A repeater system consists of a linked
transmitter/receiver combination installed in a
prominent location. The repeater is designed to
receive signals on a designated channel and
re-transmit them on another channel.
Repeaters are usually located on hills,
mountains or tall buildings. The increased
elevation greatly improves the range of the
repeater beyond that of a normal base or
mobile. This means that the repeaters are able
to receive and retransmit signals to radios that
would otherwise be out of range of each other.
Normally, UHF transceivers transmit and
receive on the same channel. This is known as
SIMPLEX operation. However, to communicate
through repeaters, your transceiver must be
