Uniden UBC144XLT - Manual (Page 9)

The UBC144XLT has 16 memory channels, each of which can be programmed to
store 1 frequency within the band of frequency coverage, (For a listing of frequency
ranges and bands, see "Technical Specifications" on page 16.)
Scanning Overview
When you press (•
scah ')
, each of the programmed frequencies is scanned for an
active frequency (channels that are locked out are skipped) at the rate of about 15
channels per second.
When the 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
there is no responding transmission within 2 seconds, the scanning cycle resumes.
