Connect the radio wiring
All wiring on the radio should be done with the vessel power supply
turned off. While radio power is polarity protected, the fuse will
blow if connection is made wrong way round. Ensure any unused
bare wires are isolated from each other, to prevent the potential of a
short circuit.
!
Warning: never operate the radio without the antenna
connected. This may damage the transmitter.
The connectors are on the rear of the base unit, as follows:
