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 servicecenter for assistance.
Only use fuses of the specified type and rating, otherwise the
transceiver could be damaged.
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 50Ω 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

If you use the transceiver for a long period when the vehicle battery is
not fully charged, or when the engine is OFF, the battery may become
discharged, and will not have sufficient reserves to start the vehicle. Avoid
using the transceiver in these conditions.
Transmitting without first connecting an antenna or other
matched load may damage the transceiver. Always connect
the antenna to the transceiver before transmitting.
All fixed stations should be equipped with a lightning arrester to
reduce the risk of fire, electric shock, and transceiver damage.

an impedance other than 50Ω reduces the efficiency of the antenna
system and can cause interference to nearby broadcast television
receivers, radio receivers, and other electronic equipment.
