Many agencies use a two-way radio
system that might have a period of 2
or more seconds between a transmis-
sion and a reply. To keep from miss-
ing a reply, you can program a 2-
second delay into any channel or fre-
quency. The scanner continues to
monitor the frequency for 2 seconds
after the transmission stops before re-
suming scanning or searching.

To program a 2-second delay:

• If the scanner is scanning chan-

nel-storage banks and stops on
an active channel where you want
to store a delay, quickly press

 before scanning resumes.

scanner automatically adds a 2-

pears.

You can turn each channel-storage
bank on and off. When you turn off a
bank, the scanner does not scan any
of the 50 channels in that bank.

For banks 1–10, while scanning press
the number key that corresponds to
the bank you want to turn on or off.
For banks 11–20, press SHIFT, then
press the number key that corre-
sponds to the bank you want to turn
on or off.

• You can manually select any

channel within a bank, even if that
bank is turned off.

• You cannot turn off all banks. One

bank is always active.

You can scan existing channels or
search frequencies faster by locking
out channels or frequencies that have
a continuous transmission, such as a
weather channel.

Note: If you just want to skip over a
lengthy transmission (such as a mo-
dem signal), see “Skipping Data Sig-
nals” on Page 25.
