) channels each, a total
of 300 channels. You can use each channel-storage
bank to group frequencies, such as those used by Mo-
torola trunking, EDACS trunking, Marine, CB, Police,
Fire, Aircraft and Ham (see “Typical Band Usage” on
Page 67).
For example, a police department might use four fre-
quencies, one for each side of town. You could program
the police frequencies starting with
òòò

(the first channel
in bank 0) and program the fire department frequencies
starting with

(the first channel in bank 1). The first

Search Banks
Your scanner has five preprogrammed search banks
and one limit search bank. You can set the lower and
higher frequency limit in the limit search bank. (For the
default setting, see “Searching a Preprogrammed Fre-
quency Range” on Page 30).
UNDERSTANDING YOUR SCANNER'S
MODES
You can program each channel with any of four receive
modes (AM, FM, MOT, and ED). However, you can not
program MOT (Motorola), or ED (EDACS) mode in VHF.
Each receive mode affects how your scanner operates
when scanning and receiving transmissions, and also af-
fects what transmissions you receive when you set the
scanner to the closed mode. See “Changing the Receive
Mode” on Page 46.
AM Mode
The AM mode sets the scanner to receive transmissions
using amplitude modulation (AM), primarily used for air-
craft, military, some amateur radio, and some govern-
ment transmissions. (Refer to “Specifications” on
Page 81 for a list of the frequencies covered.) When the
scanner receives a transmission on a channel set to the
AM mode, it always stops on the transmission.
