Frequency — the receving signal location (expressed in MHz). To find 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 finds an active frequency, it stops and monitors the radio traffic 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 specifically 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”.
