Using Your CB

±"016'"±"

•Before calibration, end CB transmission and make sure the CB is not tuned to the Emergency channel 9 or 19 or in PA mode.

•Do not calibrate the compass near metal or a strong magnetic field.

•The compass is not available in TX mode.

2.To transmit, hold down PUSH TO TALK on the microphone. Hold the microphone 2–3 inches from your mouth and speak in a normal tone of voice.

3.Turn VOLUME for the desired volume level. If you hear high-pitched squeal, turn VOLUME counterclockwise until the squeal stops.

4.To turn off the PA amplifier, turn the transceiver off. Or, set PA/MON/CB to CB for CB communication.

You can use your CB as a receiver to listen to transmissions on an optional PA speaker. With a PA speaker connected, set PA/MON/CB to MON. Your CB cannot transmit and you hear sound only from the external PA speaker.

You can easily view your current heading at a glance. There are eight cardinal points on the display — north, northeast, east, southeast, south, southwest, west, northwest. Calibration helps the compass better separate the earth’s magnetic field from the magnetic field generated by external influences (such as your vehicle), providing more accurate heading information.

Calibrate the compass anytime you move it, or whenever distortion continuously appears. Before calibration, peel off the backing on one side of the supplied tape and attach the tape to the back of the compass, then mount the compass by peeling off the backing on the other side of the tape, then press the compass onto the level mounting surface, with the compass’ arrow facing up and pointing to the front. Do not mount the compass upside down.

1.Hold down CAL for a second. All eight cardinal points flash.

2.Drive your vehicle in two complete circles. Be sure your vehicle is on level ground, in an open area, such as a parking lot.

3.Press CAL to confirm calibration

You must complete the circles on level ground and press CAL within 10 minutes. Or, start from Step 1 again.

If an error is found during calibration, ;h appears for a few seconds. Move the compass to another place and start from Step 1 again.
