Frequency — the receving signal location (expressed in
MHz). To fi nd active frequencies, you can use frequency
guides available from your local RadioShack store, frequency
listings posted on the Internet, or the built-in search function.
Channels — programmable memory locations for the
frequencies you want to monitor. Each time the scanner fi nds
an active frequency, it stops and monitors the radio traffi c
on that channel until the transmission ends, then resumes
scanning.
Channel Storage Banks — a storage area for a group of
channels. Channels are storage areas for frequencies.
Whereas a channel can only contain one frequency, a bank
can hold numerous channels.
Talkgroup IDs — each channel storage bank has an
associated talkgroup ID list, for a total of 10 talkgroup ID
lists. Each ID list has 5 sub-banks. Each sub-bank has 30
ID locations. You can program up to 150 talkgroup IDs in
each bank, so you can program up to 1500 talkgroup IDs
in 10 banks. When the scanner stops on a transmission in
the Motorola or EDACS mode, it checks to see if the ID has
been stored in the associated ID list. In the Closed Mode, the
scanner only stops on the transmission and displays its text
tag if you have stored and not locked out the ID. In the Open
Mode, the scanner always stops on all transmissions except
those you specifi cally exclude, and diplays the ID’s text tag
if you have stored the ID. For a detailed description of Open
and Closed Mode operation, see “Open and Closed Mode
Operation”.
