OPERATION

Before you start using your TRC-239, we recom- mend you read “CB Operation Tips” on Page 17, which contains information to help you use the TRC- 239 effectively and courteously.

RECEIVING TRANSMISSIONS AND ADJUSTING SQUELCH

Caution: Before receiving or transmitting, always connect the antenna.

1.Rotate SQUELCH fully towards the top of the CB.

2.Rotate VOLUME toward the bottom of the CB until it clicks. The CB turns on and a channel appears. Increase the volume to a comfortable listening level. (You might hear a hiss if there is no signal on the selected channel.)

3.Press CH 9 or 8 until the desired channel appears on the display. To move rapidly through the channels, hold down 9or 8.

4.Rotate SQUELCH toward the bottom of the TRC- 239 until any hiss just stops. This lets you hear transmissions without background noise. Rotat- ing the control further decreases the TRC-239’s sensitivity to incoming signals.

5.To turn off the TRC-239, rotate VOLUME upward until it clicks.

TRANSMITTING

1.Follow Steps 1–4 in “Receiving Transmissions and Adjusting Squelch.”
