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 (
ò
òò
ò
to
é
éé
é
) of
30 (
òò
òòòò
òò
to
ðé
ðéðé
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
òòò
òòòòòò
òòò
(the first channel in bank 0)
and program the fire department frequencies
starting with
ñòò
ñòòñòò
ñòò
(the first channel in bank 1).
The first digit identifies the bank (

). The
second and third digits identify the channel
within the bank (

).
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.
