setting the squelch level
The squelch feature reduces the level of static on the speaker by fi ltering 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 fi lters out channel noise and lets only
actual radio transmissions through.

Noise
While listening to a channel, adjust the SQUELCH knob until the noise is fi ltered 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.
note: setting the squelch level too high may prevent you from hearing weaker
transmissions. If you are having diffi culty hearing a transmission, try setting
the squelch level lower.
