The Basics

using your scanner

turning on the scanner
and setting squelch

1. To turn on the scanner, turn

VOL

clockwise.

VOL

WELCOME

appears. After about 3 seconds, you

might hear a hissing sound. Then adjust

VOL

a comfortable level.

2. Turn

fully counterclockwise, then turn

clockwise until the hissing sound stops.

3. To turn off the scanner, turn

VOL

counterclockwise to

OFF

The scanner does not scan if there are no

frequencies stored in channels. If the scanner

does not scan and you have already stored

frequencies in channels, turn

clockwise.

• If the scanner picks up unwanted, partial, or

very weak transmissions, turn

clockwise

to decrease the scanner’s sensitivity to these

signals. If you want to listen to a weak or

distant station, turn

counterclockwise.

• If

is adjusted so you always hear a hissing

sound, the scanner will not scan properly.

• If

is adjusted precisely at the threshold

where the hissing sound stops, the radio will

be most sensitive to very weak signals. The

radio may also receive unwanted noise or

signals that are too weak to understand. Most

users prefer to position the squelch control

a little bit past the point of threshold to avoid

receiving noise or signals that are too weak to

understand.
