USING THE SCANNER 
AS A BASE STATION
You can place this scanner on a desk,
shelf, or table to use it as a base sta-
tion.
Your scanner’s front feet fold up and
down. Adjust them to give you the
best view of the display.
Using the Supplied AC 
Adapter
Cautions:
• Use only the supplied AC adapter.
Using a different adapter can
damage your scanner and could
present a safety hazard.
• To prevent electric shock, the
plug’s blades are polarized and fit
only one way. If the plug does not
fit easily, turn it...

If power is continuously supplied to
the scanner for at least 24 hours, the
memory backup circuit maintains the
channels stored in memory for up to 5
days. If power is disconnected and the
memory backup circuit becomes too
weak to save the scanner’s program-
ming, 
MEMO LOSS appears again
when power is reconnected until you
reprogram the scanner.

UNDERSTANDING YOUR SCANNER
Once you understand a few simple
terms we use in this manual and famil-
iarize yourself with your scanner’s fea-
tures, you can put the scanner to work
for you. You simply determine the com-
munications you want to hear, then set
the scanner to scan those frequencies.
A 
frequenc
y is the tuning location of a
station (expressed in kHz or MHz). To
find active frequencies, you can use
the 
search function to search 
search
bands, which are preset ranges of fre-
quencies. When...

14
PRIVATE Bank
Your scanner has one PRIVATE bank.
This bank contains 20 channels. You
can store frequencies from any search
band (see “Search Bands” on
Page 15), service search bank, or any
weather frequency into these chan-
nels, then scan the channels by press-
ing 
PRIVATE.
Notes:
• You cannot use the 
SEARCH key
to search for new frequencies in
the PRIVATE bank.
• You cannot scan the PRIVATE
bank until you have stored fre-
quencies in its channels (see
“Storing Frequencies into Chan-
nels” on Page...

15
SEARCH BANDS
Your scanner has 11 preprogrammed search bands. Each band covers a specific
range of frequencies which you can search for specific broadcasts by using the
SEARCH and BAND keys. For example, you can search through all frequencies be-
tween 29.000 and 30.000 MHz for specific broadcasts.
This table shows the search band range displayed by the scanner and the typical
usage, frequency coverage, and step rate for each search band range.
Notes:
• Your scanner searches at the preset frequency...

16
While searching through a search
band, you might hear a frequency
that you want to store with other fre-
quencies of the same type, so you
can scan them all together. You can
store any frequency into a channel in
the POLICE or FIRE/EMG service
search banks or the PRIVATE bank.
See “Storing Frequencies into Chan-
nels” on Page 21.
Notes:
• Some of the frequencies in the
search bands are also included in
the scanner’s service search
banks.
• When you store a frequency in a
channel, that frequency also...
