UNDERSTANDING BANKS
Channel Storage Banks
To make it easier to identify and select the channels you
want to listen to, channels are divided into 10 banks (0–9)
of 50 (00 to 49) channels each. Use each channel-stor-
age bank to group frequencies, such as those used by
the police department, fire department, ambulance ser-
vices, or aircraft (see “Guide to the Action Bands” on
Page 67). For example, the police department might use
four frequencies, one for each side of town. You could
program the police frequencies starting with 000 (the 1st
channel in bank 0) and program the fire department fre-
quencies starting with 100 (the 1st channel in bank 1).
The 1st digit identifies the bank (0–9). The 2nd and 3rd
digits identify the channel within the bank (00–49).
Search Banks
This scanner is able to search 10 search banks. You can
also replace a bank with one of the 60 pre-programmed
service bands. (For the default setting, see “Searching a
Preprogrammed Frequency Range” on Page 41).

bands
