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

Ω
. The extemal speaker jack accepts a
3.5mm(1/8’’)mono (2-conductor) plug.
