A LOOK AT THE DISPLAY
The display has indicators that show the scanner’s cur-
rent operating status. The display information helps you
understand how your scanner operates.
BANK A or
 B — appears with numbers (1–10). A or B
indicates the bank group. The numbers show which
channel-storage banks are turned on for scanning.
TRUNK — appears when you select the trunking opera-
tion and while you store a trunking frequency into a
channel.

UNDERSTANDING BANKS
Service Banks
The scanner is preprogrammed with all the frequencies
allocated to the weather, ham, marine, aircraft, and po-
lice (fire/emergency) services. This helps you quickly
find active frequencies instead of doing a limit search
(see “Service Bank Search” on Page 29).
Channel Storage Banks
To make it easier to identify and select the channels
you want to listen to, all the channels are divided into
main bank groups A and B. Each main bank group has
10 banks of 50 channels....

STORING KNOWN FREQUENCIES 
INTO CHANNELS
You can locate and store specific frequencies into
channels for later use. To assist you in locating a de-
sired frequency from the scanner’s wide range, consid-
er using a frequency guide. Good references for active
frequencies are the RadioShack “Police Call Guide in-
cluding Fire and Emergency Services,” and “Official
Aeronautical Frequency Directory.” We update these
directories every year, so be sure to get a current copy.
Note:
 To store trunked system...

SEARCHING FOR AND 
TEMPORARILY STORING ACTIVE 
FREQUENCIES 
If you do not have a reference to frequencies in your ar-

search,  press:
•
DELAY if you want the scanner to pause 2 seconds
after a transmission ends before it proceeds to the
next frequency (see “Delay” on Page 33).

or V
 to search from the lower to the upper limit.
6. When the scanner stops on a transmission, quickly

transmission. 
HOLD appears.
