Check the battery polarityand voltage of the vehicle before installing the transceiver.1 Check for an existing hole, conveniently located in the fi rewall, where thepower cable can be passed through.• If no hole exists, use a circle cutter to drill a hole, then install a rubber grommet.2 Run the power cable through the fi rewall and into the engine compartment.3 Connect the red lead to the positive (+) battery terminal and the black leadto the negative (–) battery terminal.• Place the fuse as close to the battery as possible.4 Coil the surplus cable and secure it with a retaining band.• Be sure to leave enough slack in the cables so the transceiver can be removedfor servicing while keeping the power applied.■ Installing the TransceiverFor passenger safety, install the transceiver securely using the supplied or optional mountingbracket and screw set, so the transceiver will not break loose in the event of a collision.Note:• Before installing the transceiver, check how far the mounting screws will extend below thesurface. When drilling mounting holes, be careful not to damage vehicle wiring or parts.1 Mark the position of the holes in the dash, using the mounting bracket as atemplate. Using a 4.2 mm (5/32 inch) drill bit, drill the holes, then attach themounting bracket using the supplied screws.• Mount the transceiver within easy reach of the user and where there is sufficientspace at the rear of the transceiver for cable connections.2 Connect the antenna and the supplied power cable to the transceiver.3 Slide the transceiver into the mounting bracket and secure it using thesupplied hex-headed screws.
