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 anothertransmission 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 programmedfrequencies that are stored in the
scanner's channels 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 "Programmingwith Search" on
page 14. The mainpurpose of the Search function is to help you find
active frequencies to program into memory.
