Antenna
A key element in the performance of any communication sys-
tems is its antenna. Contact your dealer for more information
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, re-
pair it and then replace the damaged fuse with a new rated
one.
*Depending on version, only one fuse holder may be attached.
❑
Fuse rating: 10 A (for one fuse holder)/20 A (for Two 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 benzine or
alcohol, as they will damage the transceiver sur-
faces.
