Operation
Setting the Squelch
1. To turn the unit ON, rotate VOLUME clockwise.
Adjust volume to a comfortable level.
Note: You must select achannel which is not in use before setting the SQUELCH
control on your radio.
2. Think of the Squelch control as a gate. If you turn SQUELCH fully clockwise it
raises the "Squelch Gate" so high that no signals get through.

3. If you turn the SQUELCH fully counterclockwise it lowers the "Squelch Gate" so
that everything gets through - noise, weak signals, and strong signals.

4. To set the "Squelch Gate" to the desired level, turn SQUELCH counterclockwise
until you hear noise. Then turn the SQUELCH clockwise just until the noise stops.
Now only strong signals get through.
