Notes:
• The scanner does not scan if there are no frequen-
cies stored in channels. If the scanner does not
scan and you have already stored frequencies in
channels, turn
SQUELCH
further clockwise.
• If the scanner picks up unwanted, partial, or very
weak transmissions, turn
SQUELCH
clockwise to
decrease the scanner's sensitivity to these signals.
If you want to listen to a weak or distant station, turn
SQUELCH
counterclockwise.
•If
SQUELCH
is adjusted so you always hear a hiss-
ing sound, the scanner will not scan properly.
• To ensure the scanner operates properly while in
the trunking mode, we suggest you set
SQUELCH
using the steps listed above.
