CONNECTIONS AND MAINTENANCE

CAUTION: After connecting the DC power cable, NMEA

IN/OUT leads, external speaker lead and hailer/foghorn lead,

cover the connector and leads with an adhesive tape as

shown below, to prevent water seeping into the transceiver.

■ Antenna

A key element in the performance of any communication sys-

tem is the antenna. Ask your dealer about antennas and the

best place to mount them.

■ Fuse replacement

One fuse is installed in the supplied DC power cable. If a fuse

blows or the transceiver stops functioning, track down the

source of the problem if possible, and replace the damaged

fuse with a new one of the proper rating.

■ Supplied accessories

■ Microphone hanger

Rest the supplied microphone on the hanger when not in use.

Connect the OPC-1096* to the transceiver’s ground terminal

with a self-tapping screw (3 × 8 mm) and the other side to the

microphone hanger to use the microphone hanger function.

*Depending on version.

• If the microphone hanger function is used, Channel 16 is selected

automatically when the supplied microphone is rested on the

hanger.
