appears. Then, after about 3 sec-
onds, you hear a hissing sound.
3. Turn

leave it set to a point just after the
hissing sound stops.

Notes:
• 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
SQUELCH
further clock-
wise.
• If the scanner picks up
unwanted, partial, or very weak
transmissions, turn
SQUELCH
clockwise to decrease the scan-
ner’s sensitivity to these sig-
nals. If you want to listen to a
weak or distant station, turn
SQUELCH
counterclockwise.
• If
SQUELCH
is adjusted so you
always hear a hissing sound,
the scanner will not scan prop-
erly.
• To ensure the scanner operates
properly while in the trunking
mode, we suggest you set
SQUELCH
using the above
steps, even if the scanner is
automatically muted.
