Is there anyway to listen to the CB only? The radio is always on. Sometimes I just want the CB. How do I adjust the squelch if the radio is always playing? I hope its not too obvious.

 

I believe you can put the volume on the radio all the way down which will mute it. Then switch over to the CB and use the volume control. The CB has an independent volume control separate from the radio.

 

Only way is mute Radio volume and turn CB on. Radio is your main head unit.

 

The squeltch can be adjusted no matter what mode you are in provided that the CB is on. To listen to just the CB you turn the radio volume down to mute as already stated.
