CONNECTION AND MAINTENANCE
■
Antenna
A key element in the performance of any communication
systems is an antenna. Contact your dealer for more infor-
mation regarding antennas and how to install them.
■
Fuse replacement
A fuse is installed in each fuse holder of the supplied DC
power cable*. If a fuse blows or the transceiver stops func-
tioning, track down the source of the problem if possible, and
then replace the damaged fuse with a new rated one.
*Depending on version, only 1 fuse holder may be attached.
❑
Fuse rating: 10 A (for 1 fuse holder)/20 A (for 2 fuse holders)
USE
the applicable fuse only.
■
Cleaning
If the transceiver becomes dusty or dirty, wipe it clean with a
soft, dry cloth.
DO NOT
use harsh solvents such as benzene or
alcohol, as they may damage the transceiver sur-
faces.
