• If you program more than 20
skip frequencies, each new fre-
quency replaces old ones, start-
ing from the first stored
frequency.
• You can select the skipped fre-
quency when the scanner is in
the hold mode. The scanner dis-
plays 
LOCKOUT when you
select a skipped frequency.
• If you skip all frequencies in the
weather band or within a search
range, the scanner sounds three
beeps and will not start search-
ing.
LISTENING TO 
MONITOR MEMORIES
After you temporarily store frequen-
cies into the scanner’s monitor mem-
ories, you can listen to them by
pressing

selected channel.
SCANNING THE 
STORED CHANNELS
To scan the stored channels, press
SCAN. Your scanner scans through
all the stored channels except the
ones you lock out (see “Locking Out
Channels” on Page 27).
If necessary, readjust 
SQUELCH so
you do not hear the hissing sound
between transmissions.
TURNING CHANNEL-
STORAGE BANKS ON 
AND OFF
You can set your scanner to scan
more efficiently by turning selected
channel storage banks on or off.When you turn off a bank, the scan-
ner does not scan any of the 20
channels in the bank.
While scanning, press the number
key for the bank you want to turn on
or off. If the memory bank indicator is
on, the bank is turned on and the
scanner scans all channels within
that bank that are not locked out. If
the indicator is off, the scanner does
not scan any of the channels within
that bank.
Notes:
• You can manually select any
channel in a bank, even if the
bank is turned off.
• You cannot turn off all banks.
There must be at least one
active bank.
MANUALLY 
SELECTING A 
CHANNEL
You can continuously monitor a spe-
cific channel without scanning. This
is useful if you hear an emergency
broadcast on a channel and want to
hear all the details (even though
there might be periods of silence) or
if you want to monitor only a specific
channel or a locked-out channel.
To manually select a channel, press
MANUAL, enter the channel number,
then press

SPECIAL FEATURES
USING PRIORITY 
CHANNELS
The priority feature lets you scan
through channels and still not miss
important or interesting calls on spe-
cific channels. You can program one
stored channel in each bank as a pri-
ority channel (up to 10 stored chan-
nels in total). As the scanner scans
the bank, if the priority feature is
turned on, the scanner checks the
priority channels every 2 seconds for
activity.
The scanner automatically desig-
nates each bank’s first channel as its
priority channel. Follow these steps
to select a different channel as the
priority channel for a bank.
1. Press 
PGM.
2. Enter the channel number you
want to select as the priority
channel, then press 
PRI/HYPER
SEARCH
.   appears to the left
of the channel number.
3. Repeat Steps 1
–2 for the chan-
nel in each bank you want to
program as a priority channel.Note: If the scanner cannot find a pri-
ority channel,   
CH LOCOUt ap-
pears when you turn on the priority
feature.
To confirm all priority channel num-
bers, press 
PGM, then repeatedly
press 
PRI/HYPER SEARCH to see the
priority channels.
To turn on the priority feature, press
PRI/HYPER SEARCH during scan-
ning. 
PRIORITY appears and every
2 seconds the scanner checks the
priority channel in each bank that is
turned on, starting from the lowest-
numbered to the highest-numbered
priority channel. If there is a trans-
mission on the priority channel, the
scanner tunes the transmission until
it stops.
The scanner does not check the
channel if it is in a bank which is
turned off or if the priority channel is
locked out.
To turn off the priority feature, press
PRI/HYPER SEARCH. PRIORITY
disappears.

USING THE 2-SECOND 
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
or frequencies. Then, when the scan-
ner stops on the channel or frequen-
cy, 
DELAY appears and the scanner
continues to monitor the channel/fre-
quency for 2 seconds after the trans-
mission stops before it resumes
scanning or searching.
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
 DELAY before it
starts to scan again. 
DELAY
appears.
• If the desired channel is not
selected, manually select the
channel then press 
DELAY.
DELAY appears• If the scanner is searching,
press 
DELAY during the search.
DELAY appears and the scan-
ner automatically adds a 2-sec-
ond delay to every transmission
it stops on.
To turn off delay, press 
DELAY when
DELAY is displayed.
LOCKING OUT 
CHANNELS
You can set your scanner to scan
more efficiently by locking out chan-
nels you do not want to monitor. This
is handy for locking out channels
where you stored a frequency with a
continuous transmission, such as a
weather channel. 
To lock out a channel, press 
MANU-
AL
, enter the desired channel num-
ber, press 
MANUAL or PGM to select
the channel, then press 
L/O/SEARCH
SKIP 
so LOCKOUT appears.
Note: 
You can still manually select
locked out channels.

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. 
GUIDE TO FREQUENCIES
US Weather Frequencies
Canadian Weather Frequencies
Note: These frequencies are not pre-programmed in the weather service bank
but can be manually programmed into a channel.
Ham Radio Frequencies
Ham radio operators often transmit emergency information when other means of
communication break down. The following chart shows the frequencies the scan-
ner receives that Ham radio operators normally use:
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the
scanner’s receiver. These operating frequencies might interfere with broadcasts
on the same frequencies. If you program one of these frequencies, you hear only
noise on that frequency. If the interference is not severe, you might be able to
turn 
SQUELCH clockwise to cut out the birdie. 162.400 162.425 162.450 162.475 162.500 162.525 162.550
