automatically notifies you if you are about to  
store a frequency you have already stored,  
to help avoid wasting storage space.  
Scanner. This scanner gives you direct  
access to over 25,000 frequencies, including  
those used by police and fire departments,  
ambulance services, government agencies,  
air, and amateur radio services. You can  
select up to 200 channels to scan, and you  
can change your selection at any time.  
Direct Search  
— lets you search for new  
and unlisted frequencies starting from a  
specified frequency.  
Priority Channel  
— lets you program a  
frequency in the priority channel to be  
scanned every 2 seconds so you do not miss  
important calls.  
The secret to your scanner's ability to scan  
so many frequencies is its built-in  
microprocessor. Your scanner also has  
these special features:  
Weather Band (WX) Key  
— scans seven  
preprogrammed weather frequencies to keep  
you informed about current weather  
conditions.  
Four Service Banks  
— let you search  
preset frequencies in separate fire/police, air,  
ham radio, and marine banks, to make it  
easy to locate specific types of calls.  
Weather Alert  
— automatically sounds the  
alarm tone to advise of hazardous weather  
conditions when the scanner detects an alert  
signal on the local NOAA weather channel.  
Two-Second Scan Delay  
— delays  
scanning for 2 seconds before moving to  
another channel, so you can hear more  
replies.  
Lock-Out Function  
— lets you set your  
scanner to skip over specified channels or  
frequencies when scanning or searching.  
Ten Channel-Storage Banks  
— let you  
store up to 20 channels in each of 10  
different banks, to group channels so you  
can more easily identify calls.  
Liquid Crystal Display  
— makes it easy to  
view and change programming information  
at any time.  
20 Monitor Memories  
— let you temporarily  
save up to 20 frequencies you locate during  
a search, so you can move selected  
frequencies to channel storage later.

the laws in your area.  
Connecting an Outdoor Antenna  
Instead of the supplied antenna, you can  
connect an outdoor base-station or mobile  
antenna (neither supplied) to your scanner.  
Your local RadioShack store sells a variety  
of antennas. Choose the one that best meets  
your needs.  
CONNECTING AN ANTENNA  
Connecting the Supplied Antenna  
You must install an antenna before you can  
operate the scanner.  
When deciding on an outdoor antenna and  
its location, consider these points:  
The supplied telescoping antenna helps your  
scanner receive strong local signals. To  
install the antenna, thread it clockwise into  
the hole on top of the scanner.  
• The antenna should be located as high  
as possible.  
• The antenna and antenna cable should  
be as far as possible from sources of  
electrical noise (appliances, other  
radios, and so on).  
• The antenna should be vertical for the  
best performance.  
To connect an optional base-station or  
mobile antenna, first remove the supplied  
antenna from the scanner. Always use 50  
Ohm coaxial cable, such as RG-58 or RG-8,  
to connect the base-station or mobile  
antenna. For lengths over 50 feet, use RG-8  
low-loss dielectric coaxial cable. If the  
antenna cable's connector does not fit in the  
ANT  
jack on the back of the scanner, you  
The scanner's sensitivity depends on its  
location and the antenna's length. For the  
best reception of the transmissions you want  
might also need a PL-259-to-Motorola  
antenna plug adapter. Your local  
RadioShack store carries a wide variety of  
coaxial antenna cable and connectors.  
Once you choose an antenna, follow the  
mounting instructions supplied with the  
antenna. Then route the antenna's cable to

ANT  
jack.  
Warning:  
Use extreme caution when you  
install or remove an outdoor antenna. If the  
antenna starts to fall, let it go! It could contact  
overhead power lines. If the antenna touches  
a power line, contact with the antenna, mast,  
Caution:  
Do not run the cable over sharp  
edges or moving parts that might damage it.

service-search  
Once you understand a few simple terms  
used in this manual and familiarize yourself  
with your scanner's features, you can put the  
scanner to work for you. You simply  
determine the type of communications you  
want to receive, then set the scanner to scan  
them.  
You can also search the  
banks

Service Banks  
The scanner is preprogrammed with the  
frequencies allocated by fire/police, aircraft,  
ham radio, and marine services. In these  
service banks, you can search through the  
frequencies and store them in channels for  
fire/police, aircraft, ham radio, and marine  
banks. This is handy for quickly finding active  
frequencies instead of searching through an  
entire band.  
Note:  
The frequencies in the scanner's  
service bank are preset. You cannot change  
them.

Banks” on Page 11).  
Searching the Service Banks  
Your scanner contains groups of preset  
frequencies called service banks. Each  
service bank is associated with a specific  
activity (see “Understanding Service Banks/  
Banks” on Page 10). You can search for fire/  
police, air, ham, and marine transmissions  
even if you do not know the specific  
frequencies that are used in your area. Then  
you can store the frequencies you found into  
the scanner's channels or monitor memories.  
To pause the search while receiving a  
signal, press and release 8 or 9.  
To continue the search, hold down 8  
or 9 for about 2 seconds.  
To move quickly up or down through  
the frequencies, press and hold down  
8 or 9. The scanner tunes through  
the frequencies until you release 8

BIRDIE FREQUENCIES  
Every scanner has birdie frequencies.  
Birdies are signals created inside the

AVOIDING IMAGE FREQUENCIES  
You might discover one of your regular stations on another frequency that is not listed. It might  
be what is known as an image frequency. For example, you might find a service that regularly  
uses a frequency of 453.275 also on 474.675.  
To see if it is an image, do a little math.  
Note the new frequency.  
474.675  
Double the intermediate frequency of 10.7 MHz (21.400)  
and subtract it from the new frequency.  
–21.400  
453.275  
If the answer is the regular frequency,  
then you have tuned to an image.  
Occasionally, you might get interference on a weak or distant channel from a strong broadcast  
21.4 MHz above or below the tuned frequency. This is rare, and the image signal is usually  
cleared whenever there is a broadcast on the actual frequency.  
FREQUENCY CONVERSION  
The tuning location of a station can be expressed in frequency (kHz or MHz) or in wavelength  
(meters). The following information can help you make the necessary conversions.  
1 MHz (million) = 1,000 kHz (thousand)  
To convert MHz to kHz, multiply the number of MHz by 1,000:  
30.62 MHz × 1000 = 30,620 kHz  
To convert from kHz to MHz, divide the number of kHz by 1,000.  
127,800 kHz ÷ 1000 = 127.8 MHz  
To convert MHz to meters, divide 300 by the number of MHz.  
300 ÷ 50 MHz = 6 meters

Scanner receives stations poorly or  
not at all.  
Check the antenna (indoor or outdoor).  
Signals may be blocked from being received by the scanner due  
to metal frames or material in the building. Change  
the scanner’s location and try again.  
The scanner’s keys do not work, or  
The scanner might be locked. Reset the scanner. If that does

Scanner.”  
Scanner does not work at all.  
Check that the power supply (AC adapter/AC outlet) is working.  
The scanner might be locked. Reset the scanner. If that does  
not work, reinitialize the scanner. See “Resetting/Initializing the  
Scanner.”  
SQUELCH

straightened paper clip, into the reset  
opening on the back of the scanner (as  
shown) and gently press then release  
the reset button inside the opening. If  
the scanner still does not work properly,  
you might need to initialize the scanner.  
If the scanner's display locks up or does not  
work properly after you connect a power  
source, you might need to reset or initialize  
the scanner.  
Important  
: If you have problems, first try to  
reset the scanner. If that does not work, you  
can initialize the scanner; however, this  
clears all information stored in your  
scanner's memory.  
Resetting the Scanner  
1. Turn off the scanner, then turn it on  
again.

Troubleshooting  
 
Initializing the Scanner  
Important  
: This procedure clears all infor-  
mation you stored in the scanner's memory.  
Initialize the scanner only when you are sure  
the scanner is not working properly.

CARE  
Keep the scanner dry; if it gets wet, wipe it  
dry immediately. Use and store the scanner  
only in normal temperature environments.  
Handle the scanner carefully; do not drop it.  
Keep the scanner away from dust and dirt,  
and wipe it with a damp cloth occasionally to  
keep it looking new.  
Modifying or tampering with the scanner’s  
internal components can cause a  
malfunction and might invalidate its warranty  
and void your FCC authorization to operate  
it. If your scanner is not performing as it  
should, take it to your local RadioShack store  
for assistance.
