SPECIAL FEATURES
USING PRIORITY 
CHANNELS
The priority feature lets you scan
through channels and still not miss
important or interesting calls on spe-
cific channels. You can program one
stored channel in each bank as a pri-
ority channel (up to 10 stored chan-
nels in total). As the scanner scans
the bank, if the priority feature is
turned on, the scanner checks the
priority channels every 2 seconds for
activity.
The scanner automatically desig-
nates each bank’s first channel as its
priority...

USING THE 2-SECOND 
DELAY
Many agencies use a two-way radio
system that might have a pause of
several seconds between a query
and a reply. To avoid missing a reply,
you can program a 2-second delay
into any of your scanner’s channels
or frequencies. Then, when the scan-
ner stops on the channel or frequen-
cy, 
DELAY appears and the scanner
continues to monitor the channel/fre-
quency for 2 seconds after the trans-
mission stops before it resumes
scanning or searching.
You can program a 2-second delay...

A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly “line-of-sight.”
That means you usually cannot hear stations that are beyond the horizon.

Canadian Weather Frequencies
Note: These frequencies are not pre-programmed in the weather service bank
but can be manually programmed into a channel.
