Ô NOTE Ô

Only rotate SQUELCH until the hissing stops. If you continue to rotate it clockwise, you will be unable to receive any signals.

You may want to purchase an SWR (Standard Wave Ratio) meter to measure your range and signal strength. This will enable you to adjust your antenna for maximum range, and determine the best position for RF GAIN. See your SWR meter owner’s manual for instruction on how to use it.

RECEIVING AND

TRANSMITTING

We recommend you try receiving transmissions before you transmit.

RECEIVING

1.Rotate OFF/VOLUME towards OFF until it clicks to turn off the CB.

2.Slide CB/WX to CB.

3.Rotate SQUELCH fully counterclockwise.

4.Rotate RF GAIN fully clockwise.

5.Rotate OFF/VOLUME clockwise to turn on the CB. The display lights and the channel number appears. An alert sounds if a weather alert signal is detected (see “Using Digital Weather Alert” on Page 10).

6.To decrease CB sensitivity so you do not hear weak, distant signals, slowly rotate SQUELCH clockwise until the hissing stops. To increase sensitivity and to receive

very weak signals, rotate SQUELCH counterclockwise.

Ô

7.Rotate RF GAIN clockwise to optimize reception

(incoming signal strength). Or, rotate it counterclockwise to decrease signal strength. Ô

8.To tune to a channel, rotate CHANNEL on the radio, or press UP or DN on the microphone. To quickly scroll through channels in either direction, hold down UP or DN until you reach the desired channel.

9.Adjust VOLUME to a comfortable listening level.

10.To turn off the CB, rotate OFF/VOLUME counterclockwise to OFF until it clicks.

TRANSMITTING

1.To transmit, hold down PTT on the microphone. Hold the microphone about 2–3 inches from your mouth and speak in a normal tone of voice. TX lights to indicate transmission.

2.When you finish transmitting, release PTT. TX turns off.
