GND TERMINAL
Connects the GX1150 to a good ground, for safety and optimum perfor-
mance.
Normally, the GND connection to the heat sink is not needed. However,
when the DC power cable connection to the radio has a long run, the
transmitter may become unstable and the receiving audio may be noisy. In
such a case, connect a large diameter, short cable between this terminal
on the heat sink and battery ground.
Install only the supplied screw or similar size
