minutes to search all these frequencies.
Search Skip Memory
You can skip up to 20 specified frequencies during a
limit or direct search and up to 20 specified frequencies
during a service bank search. This lets you avoid un-
wanted frequencies or ones you have already stored in
a channel.
To skip a frequency, press

stops on the frequency dur-
ing a limit, direct, or service
search. The scanner stores
the frequency in memory
and automatically re-
sumes the search.
To clear a single frequency from skip memory so the
scanner once again stops on it during a limit, direct, or
service bank search:
1. Press
HOLD
to hold the search.
2. Press t or s to select the frequency.

ap-pears.
3. Press
S/S
.
L/O
disappears.
To clear all the skip frequencies at once while search-
ing, press
HOLD
, then hold down
S/S
until the scanner
beeps twice (about 3 seconds).
