i DC Input Cable
Connects the radio to a DC power supply capable of delivering 12V DC.
o External Speaker Connection Cable
Connects the GX1200E to an external speaker.
Q0 GPS Receiver Connection Cable
Connects the GX1200E to a GPS receiver.
Q1 Ground Terminal (GND)
Connects the GX1200E 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 termi-
nal on the heat sink and battery ground.
Install only the supplied screw or similar size ( M3x6, Stainless
Steel ) screw.
Q2 Antenna Jack (ANT)
Connects an antenna to the transceiver. Use a marine VHF antenna with
an impedance of 50 ohms.
