SPECIAL FEATURES
DELAY
Many agencies use a two-way radio system that might
have a period of 2 or more seconds between a query
and a reply. To keep from missing a reply on a specific
channel, you can program a 2-second delay into any
channel or frequency. The scanner continues to moni-
tor the channel frequency for 2 seconds after the trans-
mission stops before resuming scanning or searching.
To program a 2-second delay:
If the scanner is
scanning and stops
on an active channel
where you want to
store a delay, quickly
press
DELAY
before it
continues scanning
again.

while the

ner automatically adds a 2-second delay to every
frequency it stops on in that band.

any of the 30 channels in that bank.
While scanning, press the number key that corresponds
to the bank you want to turn on or off. Numbers appear
at the top of the display, showing the currently selected
banks.
