◊ REPLACING FUSES
If the fuse blows, determine the cause, then correct the problem.
After the problem is resolved, replace the fuse. If newly installed
fuses continue to blow, disconnect the power cable and contact
your authorized dealer or an authorized service center for
assistance.
Fuse Location Fuse Current Rating
Transceiver 15 A
Supplied Accessory DC power cable 20 A
Only use fuses of the specified type and rating, otherwise the
transceiver could be damaged.
◊ Antenna Connection
Before operating, install an efficient, well-tuned antenna. The
success of your installation will depend largely on the type of
antenna and its correct installation. The transceiver can give
excellent results if the antenna system and its installation are
given careful attention.
Use a 50 Ω impedance antenna and low-loss coaxial feed-
line that has a characteristic impedance of 50 Ω, to match
the transceiver input impedance. Coupling the antenna to the
transceiver via feed-lines having an impedance other than 50
Ω reduces the efciency of the antenna system and can cause
interference to nearby broadcast television receivers, radio
receivers, and other electronic equipment.
The possible locations of antenna on a car are shown as
following.
If you use the transceiver for a long period when the vehicle bat-
tery is not fully charged, or when the engine is OFF, the battery
may become discharged, and will not have sufcient reserves to
start the vehicle. Avoid using the transceiver in these conditions.
NOTE
Transmitting without rst connecting an antenna or other matched
load may damage the transceiver. Always connect the antenna to
the transceiver before transmitting.
All xed stations should be equipped with a lightning arrester to
reduce the risk of re, electric shock, and transceiver damage.
