Sometimes, several seconds can pass between transmissions. To avoid missing a reply, a delay is automatically set for each channel. The scanner stops for 2 seconds after a transmission stops before it resumes scanning or searching.

To turn the delay on / off:

1. Press ./DELAY. DLY appears if the delay is on.

2. To turn on the delay, press ./DELAY again. “dly” appears if the delay is off.

Squelch and Attenuator

The squelch and attenuator control the scanner sensitivity. If you hear a hissing sound, the scanner will remain on the current channel.

To set squelch:

1.Turn off the scanner and turn SQUELCH fully counterclockwise.

2.Turn on the scanner. You should hear a hissing sound. If you set the squelch precisely at the threshold where the hiss stops, the scanner may pick up unwanted or very weak transmissions. To prevent this, set the squelch past this threshold.

3.Turn the SQUELCH clockwise to decrease the scanner’s sensitivity, turn counterclockwise to increase its sensitivity.
