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.
* The supplied ferrite core must be attached to the NMEA
in/out leads and DC power cables as illustrated at left. Fix
the ferrite core near the transceiver with the two supplied
ties to prevent it from moving.
■ 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
■ 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.
