Mechanical mounting

Note: Extreme care should be exercised when drilling into dash to avoid damage to under-dash electronic ignition, cruise control, instrument and / or accessory wiring. Your unit must be mounted so as not to interfere with air bag (SRS) operation.

Step 1: Heeding the caution, use the mounting bracket as a template for marking the location of screw holes under the dash. Use an awl, nail or other sharp pointed object to mark the metal.

Step 2: Drill a 1/8” hole for each screw hole in the mounting bracket. Attach the bracket to the dash with the 3/8” Phillips machine screws provided.

.

Step 3: Locate and secure the radio into the mounting bracket allowing working space for later power connections.

Power wiring (negative ground only).

Step 1: If you have not determined whether your vehicle has a negative or positive ground, do so now. Then disconnect the negative lead from the battery to prevent short circuits that can occur during wiring.

Step 2: With negative ground, connect the red wire (the one with in-line fuse holder) to either the ( a ) fuse block radio circuit (filtered), ( b ) cigarette lighter (unfiltered for noise), or ( c ) directly to the positive post on your battery.

(Usually, the fuse block is the most convenient connecting point. It is also possible to connect to the Accessory terminal on the fuse block, so that your CB automatically goes off when the ignition goes off, preventing accidental battery drainage.)

Note: In many new vehicles the only circuit that has noise filtering is the radio circuit. Then tightly connect the black wire directly to the vehicle’s metal frame. A good direct metal - to - metal ground is essential for optimum performance. Installations using the cigarette lighter socket for power require an extra ground wire from the radio chassis to the vehicle if the radio is not fastened to a grounded part of the vehicle.

Step 3: Plug - in the power cord to the receptacle provided on the back of the transceiver.
