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 using solvents such as benzene or alcohol,
as they may damage the transceiver surfaces.
