scanning the stored channels
To begin scanning channels, press SCAN. The
scanner scans through all non-locked channels in
the activated banks. (See “locking out channels” on
Page 48 and “turning channel-storage banks on and
off” on Page 48). When the scanner finds a transmis-
sion, it stops on it. When the transmission ends, the
scanner resumes scanning.
Notes:
If you have not stored frequencies into any
channels, the scanner does not scan.
If the scanner picks up unwanted partial, or very
weak transmissions, turn SQUELCH clockwise
to decrease the scanner's sensitivity to these
signals. To listen to a weak or distant station,
turn SQUELCH counterclockwise.
To ensure proper scanning, adjust SQUELCH
until the audio mutes.
manually selecting a channel
You can continuously monitor a single channel
without scanning. This is useful if you hear an emer-
gency broadcast on a channel and do not want to
miss any details - even though there might be peri-
ods of silence - or if you want to monitor a specific
channel.
