What is Scanning?

Unlike standard AM or FM radio stations, most two-way communications (listed below) do not transmit continuously. The UBC9000XL T scans programmed channels at the rate of up to 100 channels per second until it finds an active frequency. Scanning stops on an active frequency, and remains on that channel as long as the transmission continues. When the

transmission ends, and no response is detected, the scanning cycle resumes until another transmission is received.

An optional DELAY can be set so that the scanner stays on the channel for 2 more seconds, waiting for another transmission before resuming scanning.

Searching

Scanning and searching are similar in that they both involvefinding active frequencies within a group of frequencies. The difference is Scanning looks only at a group of programmed frequencies that are stored in the scanner'schannels and grouped into banks.

Searching looks at all the frequencies within a pre-selected range of frequencies.

If you find an interesting frequency while searching, you can store it in a channel for easier access later. See "Programming with Search" on page 14. The main purpose of the Search function is to help you find active frequencies to program into memory.
