Understanting Banks; Understanding Your Scanners Modes - GRE PSR-295 Owner's Manual

UNDERSTANDING BANKS
Channel Storage Banks
A bank is a storage area for a group of channels. Chan-
nels are storage areas for frequencies. Whereas a chan-
nel can only contain one frequency, a bank can hold nu-
merous channels.
To make it easier to identify and select the channels you
want to listen to, your scanner divides the channels into
10 banks (0 to 9) of 100 (00 to 99) channels each, a total
of 1,000 channels. You can use each channel-storage
bank to group frequencies.
Search Banks
Your scanner has six preprogrammed search banks and
one limit search bank. You can set the lower and higher
frequency limit in the limit search bank.
Note: For example, if you wanted to find active frequen-
cies between a range of 150.1000 and 150.5000, you
would put both of those frequencies in the limit search
bank.
For the default setting, see "Searching a Preprogrammed
Frequency Range" on Page 20.
UNDERSTANDING YOUR SCANNER'S
MODES
You can program each channel with any of four receive
modes (AM, FM, CTCSS, and DCS). Each receive mode
affects how your scanner operates when scanning and
receiving transmissions.
AM Mode
The AM mode sets the scanner to receive transmissions
using amplitude modulation (AM), primarily used for air-
craft, or some amateur radio transmissions. When the
scanner receives a transmission on a channel set to the
AM mode, it always stops on the transmission.
FM Mode
The FM mode sets the scanner to receive transmissions
using frequency modulation (FM), used for most public
safety transmissions, as well as broadcast, business, and
