CONNECTION AND INSTALLATION
New2001
Connector information
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
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.
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 al-
cohol, as they may damage the transceiver sur-
faces.
