Use the full length of the cable without cutting off excess even if the cable is longer than required. In particular, never remove the fuse holders from the cable. 5 Reconnect any wiring removed from the negative terminal. 6 Connect the DC power cable to the transceivers power supply connector. Press the connectors firmly together until the locking tab clicks. DC POWER CABLE CONNECTION Locate the power input connector as close to the transceiver as possible. MOBILE OPERATION The vehicle battery must have a nominal rating of 12 V. Never connect the transceiver to a 24 V battery. Be sure to use a 12 V vehicle battery that has sufficient current capacity. If the current to the transceiver is insufficient, the display may darken during transmission, or transmit output power may drop excessively. 1 Route the DC power cable supplied with the transceiver directly to the vehicles battery terminals using the shortest path from the transceiver. If using a noise filter, it should be installed with an insulator to prevent it from touching metal on the vehicle. We recommend you do not use the cigarette lighter socket as some cigarette lighter sockets introduce an unacceptable voltage drop. The entire length of the cable must be dressed so it is isolated from heat, moisture, and the engine secondary (high voltage) ignition system/ cables. 2 After the cable is in place, wrap heat-resistant tape around the fuse holder to protect it from moisture and tie down the full run of cable. 3 To prevent the risk of short circuits, disconnect other wiring from the negative () battery terminal before connecting the transceiver. Red Black Fuse holder Fuse holder 4 1 2 Connect the transceivers DC power connector to the connector on the DC power cable. Press the connectors firmly together until the locking tab clicks. Note: For your transceiver to fully exhibit its performance capabilities, we recommend using the optional PS-60 (22.5 A, 25% duty cycle) power supply. Before connecting the DC power supply to the transceiver, be sure to switch the transceiver and the DC power supply OFF. Do not plug the DC power supply into an AC outlet until you make all connections. FIXED STATION OPERATION In order to use this transceiver for fixed station operation, you will need a separate 13.8 V DC power supply (not included). The recommended current capacity of your power supply is 14 A or more. 1 Connect the DC power cable to the regulated DC power supply and ensure that the polarities are correct (Red: positive, Black: negative). Do not directly connect the transceiver to an AC outlet. Use the supplied DC power cable to connect the transceiver to a regulated power supply. Do not substitute a cable with smaller gauge wires.

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. rev i ecsnarTA51 yrosseccAde i l ppuS e l baCrewoPCD A02 Fuse LocationFuse Current Rating 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 impedance antenna and low-loss coaxial feed line that has a characteristic impedance of 50 , to match the transceiver input impedance. Coupling the antenna to the transceiver via feed lines having an impedance other than 50 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. Feed line connector Antenna connector To antenna 6 1 ACCESSORY CONNECTIONS EXTERNAL SPEAKER If you plan to use an external speaker, choose a speaker with an impedance of 8 . The external speaker jack accepts a 3.5 mm (1/8) mono (2-conductor) plug. We recommend using the SP-50B speaker. MICROPHONE For voice communications, connect a 600 microphone equipped with an 8-pin modular plug into the modular socket on the front of the main unit.
