MONITOR MEMORIES
The scanner has 20 monitor memories that you can use to tem-
porarily store frequencies while you decide whether to save
them into channels. This is handy for quickly storing an active
frequency when you are searching through an entire band. You
can store a frequency into a monitor memory during a service
bank, or direct search. See “Finding and Storing Active Fre-
quencies” on Page 28.
You can select monitor memories manually, but you cannot
scan them. See “Listening to a Monitor...

OPERATION
TURNING ON THE SCANNER/SETTING 
VOLUME AND SQUELCH
1. Turn SQUELCH fully counterclockwise (until the indicator
points to 
MIN) before you turn on the scanner.
2. To turn on the scanner, turn 
VOLUME clockwise until you
hear a hissing sound.
3. Turn 
SQUELCH clockwise, just until the hissing sound stops.
Notes:
• To listen to a weak or distant station, turn 
SQUELCH coun-
terclockwise. If reception is poor, turn 
SQUELCH clock-
wise to cut out weak transmissions.
• If 
SQUELCH is adjusted so...

Resetting the Scanner
1. Turn off the scanner, then turn it on again.
2. Insert a pointed object, such as a straightened paper clip,
into the reset opening on the side of the scanner (as
shown). Then gently press the reset button inside the open-
ing. Information disappears from the display as you press
the reset button.
Note:
 If the scanner still does not work properly, you might need
to initialize the scanner (see “Initializing the Scanner”).

STORING KNOWN FREQUENCIES INTO 
CHANNELS
Good references for active frequencies are the RadioShack Po-
lice Call Guide including Fire and Emergency Services
, Official
Aeronautical Frequency Directory
, and Maritime Frequency Di-
rectory
. We update these directories every year, so be sure to
get a current copy.
Follow these steps to store frequencies into channels.
1. Press 
MAN, enter the channel number (1–200) where you
want to store a frequency, then press 
PGM. The channel
number appears.
2. Use...

28
•Press DELAY if you want the scanner to pause 2 seconds
on this channel before it proceeds to the next channel
after a transmission ends (see “Delay” on Page 36). The
scanner also stores this setting in the channel.
4. To program the next channel in sequence, press 
PGM and
repeat Steps 2 and 3.
FINDING AND STORING ACTIVE 
FREQUENCIES
Searching the Service Banks
Your scanner contains groups of preset frequencies called ser-
vice banks. Each service bank is associated with a specific ac-
tivity (see...

• To pause the search while receiving a signal, press s
 or
t
. To resume searching, hold down s
 or t
.
• To quickly move up or down through the frequencies, hold
down s
 or t
. The scanner tunes through the frequencies
until you release s
 or t
.
• If necessary, you can select search groups using the
number keys.
3. When the scanner finds an active frequency, it stops
searching and displays the frequency’s number. To store the
displayed frequency in the lowest available channel, press
PGM then ENT....

30 Note:
 You can use the scanner’s delay feature while using di-
rect search.
1. Press 
MAN then enter the frequency (including the decimal
point) you want to use as a starting point for the search.
Note:
 To start from a frequency already stored in one of
your scanner’s channels, press 
MAN and enter the desired
channel number, then press 
MAN again.
2. Hold down s
 or t
 for about 1 second to search up or down.
–d–, SRCH, and s
 or t
 appear.
Notes:
• To reverse the search direction at any time, hold...
