. SEARCH The Search function is different from Scan.
When you select a frequency band to search, the
scanner searches for any active frequency within the
lower and upper limits you specify. When an active
frequency is found, the scanner stops on that frequency
as long as the transmission lasts. If the Delay Mode is
on, the scanner remains on the same channel for 2
more seconds, waiting for a responding transmission. If
there is no responding transmission within 2 seconds,
the search cycle resumes.
When the USC 220XL T is on SCAN Mode, the display will look
