OUT leads, external speaker lead and hailer/foghorn lead,
cover the connector and leads with an adhesive tape as

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 dam-
aged fuse with a new one of the proper rating.
