MOVING A FREQUENCY FROM THE 
MONITOR MEMORY TO A CHANNEL
1. Press MANUAL, enter the channel number where
you want to store the frequency, then press 
PGM.
PGM, the frequency number or 000.0000, and the
selected channel number appear.
2. Press 
MON. MON and the frequency appear and the
channel number flashes.
3. Press 
E. MON disappears, the channel number stops
flashing, and the scanner stores the frequency in the
selected channel.
MONITORING A STORED CHANNEL
You can continuously monitor a specific channel without
scanning. This is useful if you hear an emergency broad-
cast on a channel and do not want to miss any details —
even though there might be periods of silence — or if you
simply want to monitor that channel. 
Follow these steps to manually select a channel.
1. Press 
MANUAL.
2. Enter the channel number.
3. Press 
MANUAL again.

SCANNING THE CHANNELS
To begin scanning channels or to start scanning again af-
ter monitoring a specific channel, press 
SCAN. 
SCAN and   appear, and the scanner begins to rapidly
scan upward until it finds an active frequency.
If the scanner finds an active frequency, it stops and dis-
plays that channel and frequency number, then it automat-
ically begins scanning again when the transmission ends
on that frequency.
Notes:
• You must store frequencies into channels before the
scanner can scan them (see “Storing Active Fre-
quencies” on Page 27).
• To change the scanning direction, press   or  .
• The scanner does not scan empty channels.

To listen to the frequency stored in the monitor memory,
press 
MANUAL then MON. MAN, MON, and the frequency
stored in the monitor memory appear.
CLEARING A CHANNEL
1. Press MANUAL.
2. Use the number keys to enter the channel number
containing the frequency you want to delete, then

PGM. Or, repeatedly press PGM until the
desired channel number appears. 
PGM appears.
3. Press 
CLEAR. The frequency number flashes.
4. Press 
L-OUT. L/O (lockout — see “Locking Out a
Channel” on Page 36) appears, the channel number

LISTENING TO A WEATHER BAND
The FCC (Federal Communications Commission) has al-
located channels for use by the National Oceanic and At-
mospheric Administration (NOAA). Regulatory agencies
in other countries have also allocated channels for use by
their weather reporting authorities. 
Your local weather reporting authority broadcast your lo-
cal forecast and regional weather information on one or
more of these channels.
To hear your local forecast and regional weather informa-
tion, simply press 
WX. Your scanner scans through the
weather band, and   and 
WX appear. Your scanner
should stop within a few seconds on your local weather
broadcast.
If the broadcast is weak, press   or   to resume scan-
ning.
To reverse the scanning direction, press   or  .
To manually select a specific preprogrammed weather
channel, repeatedly press 
WX until MAN appears, then:
• Repeatedly press   or   to move forward or back-
ward through the channels.
• Press the 1-digit number (0–9) of the channel you
want to listen to.

SPECIAL FEATURES
DELAY
Many agencies use a two-way radio system that might
have a pause of several seconds between a query and
a reply. To avoid missing a reply, you can program a
2-second delay into any of your scanner’s channels.
Then, when the scanner stops on the channel, 
DELAY
appears and the scanner continues to monitor the channel
for 2 seconds after the transmission stops before it re-
sumes scanning.
You can program a 2-second delay in any of these ways:
• If the scanner is scanning and stops on an active
channel, quickly press 
DLY before it starts to scan
again.
• If the desired channel is not selected, manually select
the channel then press 
DLY.
• If the scanner is searching, press 
DLY during the
search. 
DELAY appears and the scanner automatically adds a 2-
second delay to every transmission it stops on.
To turn off the delay, press 
DLY when DELAY is displayed.
LOCKING OUT A CHANNEL
You can scan existing channels faster by locking out a
channel that has a continuous transmission, such as a
weather channel.
To lock out a channel, select the channel then press
L-OUT. L/O appears.

To remove the lockout from a channel, manually select the
channel then press 
L-OUT until L/O disappears.
Notes:
• You can still manually select locked-out channels.
• Your scanner automatically locks out empty chan-
nels.
USING THE DISPLAY BACKLIGHT
You can turn on the display’s backlight for easy viewing in
dimly-lit areas. Press 
LIGHT to turn on the display light for
5 seconds. To turn off the light before it automatically turns
off, press 
LIGHT again.

TURNING THE KEY TONE ON AND 
OFF
Each time you press any of the scanner’s keys (except
 and 
LIGHT), the scanner sounds a tone. 
Follow these steps to turn the scanner’s key tone off or
back on.
1. If the scanner is on, turn 
VOLUME counterclockwise
until it clicks to turn it off.
2. While you hold down the 
2 and E keys, turn on the
scanner.
3. After 1 second, release 
2 and E.
USING THE KEYLOCK
Once you program your scanner, you can protect it from
accidental program changes by turning on the keylock
feature. When the keypad is locked, the only controls that
operate are 
LIGHT, VOLUME, and SQUELCH (and the
scanner continues to scan channels).
To turn on the keylock, hold down   for about 3 sec-
onds until   appears. The scanner beeps three times (if
the key tone is turned on). To turn it off, hold down   for
about 3 seconds until   disappears.

A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is
mainly “line-of-sight.” That means you usually cannot hear
stations that are beyond the horizon.

Ham Radio Frequencies
Ham radio operators often transmit emergency informa-
tion when other means of communication break down.
The following chart shows the frequencies the scanner re-
ceives that Ham radio operators
 normally use:

Birdie Frequencies
Every scanner has birdie frequencies. Birdies are sig-
nals created inside the scanner’s receiver. These operat-
ing frequencies might interfere with broadcasts on the
same frequencies. If you program one of these frequen-
cies, you hear only noise on that frequency. If the interfer-
ence is not severe, you might be able to turn 
SQUELCH
clockwise to cut out the birdie.
The birdie frequencies on this unit to watch for are: 
To find the birdies in your scanner, begin by disconnecting
the antenna and moving it away from the scanner. Make
sure that no other nearby radio or TV sets are turned on
near the scanner. Use the search function and scan every
frequency range from its lowest frequency to the highest.
Occasionally, the searching will stop as if it had found a
signal, often without any sound. That is a birdie. Make a
list of all the birdies in your scanner for future reference.30.735 37.800 38.400
