CONNECTION AND MAINTENANCE
■ Antenna
A key element in the performance of any communication sys-
tem is an antenna. Contact your dealer about antennas and
the best places to mount them.
■ Fuse replacement
A 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 rated one.
❑ Fuse rating: 20 A
USE the 20 A fuse only.
■ Cleaning
If the transceiver becomes dusty or dirty, wipe it clean with a
soft, dry cloth.
AVOID the use of solvents such as benzene or
alcohol, as they may damage the transceiver sur-
faces.
