■
Antenna
A key element in the performance of any communication sys-
tem is an antenna. Ask your Dealer about antennas and the
best places to mount them.
■
Fuse replacement
Two fuses are 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, rated one.

Cleaning
If the transceiver becomes dusty or dirty, wipe it clean with a
dry, soft cloth.
AVOID the use of solvents such as benzene or al-
cohol, as they may damage transceiver surfaces.
