DC INPUT CABLE

EXTERNAL SPEAKER CONNECTION CABLE
Connects the
GX1150
to an external speaker.
GPS RECEIVER CONNECTION CABLE

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 (M3x6, Stainless Steel)
screw.
ANTENNA JACK
Connects an antenna to the transceiver. Use a marine VHF antenna with
an impedance of 50 ohms.
