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.

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

1. Rotate 

 fully towards the top of the CB.

2. Rotate 

 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 

 

9

 

or 

8

 until the desired channel

appears on the display. To move rapidly through
the channels, hold down 

9

or 

8

.

4. Rotate 

 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 

 upward

until it clicks.

1. Follow Steps 1–4 in “Receiving Transmissions

and Adjusting Squelch.”
