Only use fuses of the specified type and rating; otherwise the
transceiver could be damaged.
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.
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 50Ω impedance antenna and low-loss coaxial feed line that
has a characteristic impedance of 50Ω, to match the transceiver input
impedance. Coupling the antenna to the transceiver via feed lines
having an impedance other than 50Ω reduces the efficiency of the
antenna system and can cause interference to nearby broadcast
television receiver s, radio receivers, and other electronic equipment.
Note:
• 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.
