The Basics
2. Service Scanning -- press FUNC + SVC to select one of
the service banks to fi nd an active frequency.
3. Band Search -- select a frequency band to search. The
search function is different from scanning. It searches for
any active frequency step by step within the lower and
upper limits of the band. When an active frequency is
found, the scanner will stop and stay on that frequency
as long as that transmission lasts. If that frequency is
interesting to you, press HOLD/RESUME to hold the
frequency on the display. Then program it into the private
bank you want to store. If you do not want to program
that frequency, press HOLD/RESUME or just wait until the
transmission ends. The search resumes automatically 2
seconds after the last transmission and looks for more
active frequencies.
4. Private Scanning -- the private bank is where you
program frequencies you want to store into channels.
Press PVT to scan frequencies you have programmed in
this bank.
To program frequencies, see "Storing Known Frequencies
into Channels". When scanning stops on an active frequency,
it remains on that channel as long as the transmission
continues. When the transmission ends, the scanner will
remain on the same channel for 2 more seconds, waiting for
a responding transmission. If no responding transmission
occurs within 2 seconds, the scanning cycle resumes.
