One fuse is installed in the supplied
DC power cable. If a fuse blows or the
receiver stops functioning, track down
the source of the problem, if possible.
Replace the damaged fuse with
properly rated fuse.
PC conncetion
DO NOT use a solid conductor
cable, otherwise the connected
cable may be disconnected.
CAUTION:
NEVER connect a 24 V DC
power source directly. This
will damage the receiver.
This connection is not necessary if you
have no VHF marine transceiver.
