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 KENWOOD

dealer or an authorized KENWOOD service center for

assistance.

Only use fuses of the specified type and rating; otherwise the

transceiver could be damaged.

Note: 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 under 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 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 efficiency of the

antenna system and can cause interference to nearby

broadcast television receivers, radio receivers, and other

electronic equipment.

Note: E market models use an N-type antenna connector while other

models use an M-type (SO-239) connector.

◆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.
