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. Use each channel-storage
bank to group frequencies, such as those for the police
department, fire department, ambulance services, or
aircraft (see “Guide to the Action Bands” on Page 64).
For example, the police department might use four fre-
quencies in your town while the fire department uses an
additional four. You could program the four police fre-
quencies starting with Channel 1 (the first channel in
bank 1), and program the fire department frequencies
starting with Channel 51 (the first channel in bank 2).
Monitor Memories
The scanner also has 10 temporary memory locations
called monitor memories. Use these monitor memories
to temporarily store frequencies when you search
through an entire band (see “Searching For and Tem-
porarily Storing Active Frequencies” on Page 27). You
can then move a frequency to a channel for permanent
storage. See “Moving a Frequency From a Monitor
Memory to a Channel” on Page 31. 
While you are searching frequencies, the 10 numbers
at the top of the display indicate the 10 monitor memo-
ries. 
MON appears and the flashing number beside it in-
dicates the currently active monitor memory.

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 frequencies, see “Stor-
ing Trunked Frequencies” on Page 43.
Follow these steps to store frequencies into channels.
1. Press 
MAN and hold down A/B (HOLD) for about 2
seconds to select either main bank group. Enter
the channel number where you want to store a fre-
quency, then press 
PROG. The channel number
appears. 
2. Use the number keys and 
 • (MON/CLR) to enter the
frequency (including the decimal point) you want to
store.
3. Press 
E (SVC) to store the frequency into the chan-
nel.
Notes:
• If you entered an invalid frequency in Step 2,
Error appears and the scanner beeps three
times. Enter a valid frequency. 
• The scanner automatically rounds the entered
number to the nearest valid frequency. For
example, if you enter 151.473 (MHz), your scan-
ner accepts it as 151.475.
• Press 
DELAY to pause scanning 2 seconds after
the end of a transmission before scanning pro-
ceeds to the next channel (see “Delay” on
Page 33). The scanner stores this setting in the
channel.
4. To program the next channel in sequence, press
PROG and repeat Steps 2 and 3.

SEARCHING FOR AND 
TEMPORARILY STORING ACTIVE 
FREQUENCIES 
If you do not have a reference to frequencies in your ar-
ea, use a limit, direct, or service search (except weather
service search) to find a transmission. Also see “Guide
to the Action Bands” on Page 64.
Notes: 
While doing a limit, direct, or service bank
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).
•
DATA if you want the scanner to skip data signals
(such as fax or modem signals) and search only for
audio (voice) signals (see “Skipping Data Signals”
on Page 38).
Limit Search
A limit search lets you search within a specific range
of frequencies. 
-L- appears during a limit search.
1. Press 
PROG, then LIMIT (SRC). Lo and 29.000
MHz
 appear. 29.000 MHz is the low end of the
scanner’s range.
2. Enter the frequency that is the lower limit of the
range you want to search (including the decimal
point), then press 
E.
3. Press
 LIMIT. Hi and 1300.000 MHz appear.
1300.000 MHz is the upper limit of the scanner’s
range.

range you want to search (including the decimal
point), then press 
E (SVC) again.
5. Press W
 to search from the upper to the lower limit,
or V
 to search from the lower to the upper limit.
6. When the scanner stops on a transmission, quickly
press either:
•
HOLD (A/B) to stop searching to listen to the
transmission. 
HOLD appears.
•
MON/CLR (•) to store the displayed frequency
into the current monitor memory.
7. To release the hold and continue searching, press
HOLD (A/B) or hold down W
 or V
 for at least 1 sec-
ond. Or, if you did not press 
MON/CLR (•), simply

 to continue searching. 
Direct Search 
You can search up or down from the currently displayed
frequency using direct search. 
-d- appears during
searching until the scanner stops. See Step 4.
1. Press 
MAN.
2. Enter the frequency you want to start from using
the number keys. (Press 
• to enter a decimal
point).
Notes:
• To start the search from a frequency already
stored in one of your scanner’s channels, press
MAN or PROG. Then use the number keys to
enter the channel number and then press 
MAN
or PROG again.
• If you enter an invalid frequency, the scanner
displays

Note: 
Because there are many different frequencies al-
located to fire and police departments, it can take sev-
eral minutes to search all the service frequencies.
Search Skip Memory
You can skip up to 20 specified frequencies during a
limit or direct search and up to 20 specified frequencies
during a service bank search. This lets you avoid un-
wanted frequencies or those already stored in a chan-
nel.
