SCANNING BASICS This section provides you with background on how scanning works. You don't really need to know all of this to use your scanner, but some background knowledge will help you get the most from your BC125AT. What is Scanning? Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. Your BC125AT scans programmed channels until it finds an active frequency, then stops on that frequency and remains on that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes until the scanner receives another transmission. What is Searching? The BC125AT can search for active frequencies. This is different from scanning because you are searching for frequencies that have not been programmed into the scanner. When you select frequency bands to search, the scanner searches for any active frequency within the lower and upper limits you specify. When the scanner finds an active frequency, it stops on that frequency as long as the transmission lasts. If you think the frequency is interesting, you can store it into one of the banks. If not, you can continue to search. 16

SCANNING.BASICS
This section provides you with background on how scanning
works. You don’t really need to know all of this to use your
scanner, but some background knowledge will help you get the
most from your BC125AT.
WHAT.IS.SCANNING?
Unlike standard AM or FM radio stations, most two-way
communications do not transmit continuously. Your BC125AT
scans programmed channels until it finds an active frequency,
then stops on that frequency and remains on that channel as
long as the transmission continues. When the transmission ends,
the scanning cycle resumes until the scanner receives another
transmission.
WHAT.IS.SEARCHING?
The BC125AT can search for active frequencies. This is different
from scanning because you are searching for frequencies that
have not been programmed into the scanner. When you select
frequency bands to search, the scanner searches for any active
frequency within the lower and upper limits you specify. When
the scanner finds an active frequency, it stops on that frequency
as long as the transmission lasts. If you think the frequency is
interesting, you can store it into one of the banks. If not, you can
continue to search.
