About Your Scanner

Manual Tuning

— allows you to manually

scan through the entire range of available

frequencies without programming. (See

“Specifications” on Page 52 for a list of the

available frequency ranges.)

Weather Radio

— allows you to listen to

NOAA weather broadcasts without program-

ming. See “Listening to the Weather Band”

on Page 23.

UNDERSTANDING BANKS

Channel Storage Banks

A bank is a storage area for a group of chan-

nels. Channels are storage areas for fre-

quencies. Whereas a channel 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 (

òò

éé

) of

30 (

òò

òòòò

ðé

) channels each, a total of 300

channels. You can use each channel-stor-

age bank to group frequencies, such as

those used by Motorola trunking, EDACS

trunking, Marine, CB, Police, Fire, Aircraft

and Ham (see “Typical Band Usage” on

Page 40).

For example, a police department might use

four frequencies, one for each side of town.

You could program the police frequencies

starting with

(the first channel in bank 0)

and program the fire department frequencies

starting with

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 set-

ting, see “Searching a Preprogrammed Fre-

quency Range” on Page 18).

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 (Motor-

ola), or ED (EDACS) mode in VHF. Each re-

ceive mode affects how your scanner

operates when scanning and receiving trans-

missions, and also affects what transmis-

sions you receive when you set the scanner

to the closed mode. See “Changing the Re-

ceive Mode” on Page 28.

AM Mode

The AM mode sets the scanner to receive

transmissions using amplitude modulation

(AM), primarily used for CB, aircraft, military,

some amateur radio, and some government

transmissions. (Refer to “Specifications” on

Page 52 for a list of the frequencies cov-

ered.) When the scanner receives a trans-

mission 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 transmis-

sions, as well as broadcast, business, and

amateur radio transmissions. When the

scanner receives a transmission on a chan-

nel set to the FM mode, it always stops on

the transmission.

Motorola Mode

You can set your scanner so it decodes the

talk group IDs used with Motorola trunking

systems. This setting is called the Motorola

mode.
