Turn the volume knob clockwise to increase the speaker volume; turn it counter-clockwise to 

decrease the volume. 

The squelch feature reduces the level of static on the speaker by filtering out the background 

channel noise. At the lowest squelch level, the speaker plays all radio signals, including any 

noise on the channel. Setting the squelch level higher filters out channel noise and lets only 

actual radio transmissions through.  

While listening to a channel, adjust the SQUELCH knob until the noise is filtered out and you 

can only hear the transmission. If you switch to a channel with a lot of noise or with a weak 

transmission, you may need to adjust the squelch level again.
