The Basics

step 4: set up your scanner

turn on your scanner

Turn VOL clockwise. The scanner turns on and the ALERT indicator lights for a moment. Then the alert tone beeps and TEST appears. The last setting you selected before turning the scanner off appears.

Note	The alert tone depends on the currently selected setting
	(see “Setting the Alert Tone Volume”).

set the squelch

Think of squelch as a gate. If the gate is too low (squelch too low), everything (all noise as well as signals) gets through. If the gate is set too high (squelch too high), nothing gets through. If the gate is set just right (the squelch is set properly), just the desired signals get through.

1.To set the squelch, press HOLD/RESUME to stop scanning. HOLD appears. If needed, adjust VOL until you do not hear a signal.

2.Turn SQL fully counterclockwise until you hear a hissing sound. This lowers the “squelch gate,” allowing all signals and noise to get through.

3.Turn SQL clockwise just until the hiss stops. This raises the “squelch gate,” allowing only strong signals to get through. In a city, you may want to adjust the squelch even further clockwise to decrease the range of the highway warning alert signal. This prevents the alert from sounding unnecessarily due to farther, less important sources.
