!
IMPORTANT
!
Initializing the scanner
clears all information
you stored in the
scanner’s memory.
Initialize the scanner
only when you are sure
.
Ô NOTES Ô
The scanner will not
enter scan mode if
there are no
frequencies stored in
channels, or if all
channels are locked
out in the channel
storage bank(s) that
you are attempting to
scan. In either of
these cases, the
scanner will display
All channels Locked out!.
See “Storing
Frequencies Into
Channels” on

If SQ is adjusted so
you always hear a
rushing sound, the
scanner will not scan
properly. Rotate the
SQ control until the
rushing sound stops.
If SQ is adjusted
precisely at the
threshold where the
rushing 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 SQ
control a little bit past
the point of threshold
to avoid receiving
noise or signals that
are too weak to
understand.
