2Various electronic equipment in your vehicle may malfunction if they are not properly protected fromthe radio frequency energy which is present while transmitting. Electronic fuel injection, anti-skidbraking, and cruise control systems are typical examples of equipment that may malfunction. If yourvehicle contains such equipment, consult the dealer for the make of vehicle and enlist his/her aid indetermining if they will perform normally while transmitting.Note: The following preparation instructions are for use by your KENWOOD dealer, an authorizedKENWOOD service facility, or the factory.TOOLS REQUIREDNote: Before installing the transceiver, always check how far the mounting screws will extend belowthe mounting surface. When drilling mounting holes, be careful not to damage vehicle wiring or parts.The following tools are required for installing the transceiver:ï 6 mm (1/4 inch) or larger electric drillï 4.2 mm (5/32 inch) drill bit for the 5 x 16 mm self-tapping screwsï 3.2 mm (1/8 inch) drill bit for the 4 x 16 mm self-tapping screwsï Circle cuttersPOWER CABLE CONNECTIONThe transceiver operates in 12 V negative ground systems only! Check the battery polarity andvoltage of the vehicle before installing the transceiver.1 Check for an existing hole, conveniently located in the firewall, where thepower cable can be passed through.ï If no hole exists, use a circle cutter to drill the firewall, then install a rubbergrommet.2 Run the two power cable leads through the firewall and into the enginecompartment, from the passenger compartment.3 Connect the red lead to the positive (+) battery terminal and the black lead tothe negative (ñ) battery terminal.ï Locate the fuse as close to the battery as possible.4 Coil the surplus cable and secure with a retaining band.ï Be sure to leave enough slack in the cables so the transceiver can be removed forservicing while keeping the power applied.PREPARATION
