setting the volume
Turn the volume knob clockwise to increase the speaker volume; turn it counter-clockwise to
decrease the volume.
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.
Changing the channel
Press CHAnneL UP and CHAnneL DoWn briefl y to scroll through the channels one chan-
nel at a time. Press and hold CHAnneL UP or CHAnneL DoWn to quickly scroll through
the channels.
Making a transmission
To make a transmission, press and hold the microphone PUsH to tALk button. Release the
PUsH to tALk button when you’re fi nished talking to let the other party respond.
• To prevent stuck microphone problems or situations where PUsH to tALk is pushed ac-
cidentally, the radio limits your talk time to 5 minutes in a single transmission. If you talk for
over 5 minutes continuously, the display shows RELEASE MIC BUTTON .
• For the best sound quality, hold the microphone about two inches away from your mouth.
• You cannot transmit while the radio is in weather mode or scan mode.
• See the channel lists beginning on page 38 for a list of receive-only channels.
