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. ANTENNA CONNECTION Before operating, install an efficient, well-tuned antenna. The success of your installation will depend largely on 1 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. Fuse Location Transceiver Supplied Accessory DC Power Cable Fuse Current Rating 15 A 20 A 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. ◆ 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.
