FCC NOTICE  
Your scanner might cause TV or radio interference even when it is op-  
erating properly. To determine whether your scanner is causing the in-  
terference, turn off your scanner. If the interference goes away, your  
scanner is causing it. Try to eliminate the interference by:  
• moving your scanner away from the receiver  
• connecting your scanner to an outlet that is on a different electrical  
circuit from the receiver  
• contacting your local RadioShack store for help  
If you cannot eliminate the interference, the FCC requires that you stop  
using your scanner.  
Note: Mobile use of this scanner is unlawful or requires a permit in  
some areas. Check the laws in your area.  
SCANNING LEGALLY  
Your scanner covers frequencies used by many different groups includ-  
ing police and fire departments, ambulance services, government agen-  
cies, private companies, amateur radio services, military operations,  
pager services, and wireline (telephone and telegraph) service provid-  
ers. It is legal to listen to almost every transmission your scanner can  
receive. However, there are some transmissions you should never in-  
tentionally listen to. These include:  
• telephone conversations (cellular, cordless, or other private means  
of telephone signal transmission)  
• pager transmissions  
• any scrambled or encrypted transmissions  
According to the Electronic Communications Privacy Act (ECPA), you  
are subject to fines and possible imprisonment for intentionally listening  
to, using, or divulging the contents of such a transmission unless you  
have the consent of a party to the communication (unless such activity  
is otherwise illegal).  
4
 
This scanner has been designed to prevent reception of illegal trans-  
missions. This is done to comply with the legal requirement that scan-  
ners be manufactured so as to not be easily modifiable to pick up those  
transmissions. Do not open your scanner’s case to make any modifica-  
tions that could allow it to pick up transmissions that it is not legal to lis-  
ten to. Doing so could subject you to legal penalties.  
We encourage responsible, legal scanner use.

PREPARATION  
POWER SOURCES  
You can power your scanner from any of three sources:  
• internal batteries  
• standard AC power (using an optional AC adapter)  
• vehicle battery power (using an optional DC adapter)  
INSTALLING BATTERIES  
Your scanner requires 4 AA batteries (not supplied) for power. For the  
best performance and longest life, we recommend alkaline batteries.  
Or, you can use rechargeable nickel-cadmium batteries. Both types of  
batteries are available at your local RadioShack store.  
Warning: The scanner has a built-in circuit that lets you recharge  
nickel-cadmium batteries inside the battery compartment. How-  
ever, you must never use this circuit when you have installed non-  
rechargeable batteries in the scanner. Be sure to read “Important Infor-  
mation About the External Power Jacks” on Page 9 and “Charging  
Nickel-Cadmium Batteries” on Page 12.  
Cautions:  
• Use only fresh batteries of the required size and recommended  
type.  
• Do not mix old and new batteries, different types of batteries (stan-  
dard, alkaline, or rechargeable), or rechargeable batteries of differ-  
ent capacities.  
1. Press down the tab on the battery compartment cover, and lift  
open the compartment.  
8
 
2. Install two batteries in the compartment and two in the cover as  
indicated by the polarity symbols (+ and –) marked inside each  
location.  
3. Replace the cover.  
When BATT.Loflashes and the scanner beeps every 15 seconds, im-  
mediately replace or recharge all four batteries.  
Cautions:  
• If you do not plan to use the scanner with batteries for a month or  
more, or if you plan to use only an AC or DC adapter, remove the  
batteries. Batteries can leak chemicals that can destroy electronic  
parts.  
• Dispose of old batteries promptly and properly. Do not burn or bury  
them.  
IMPORTANT INFORMATION ABOUT THE  
EXTERNAL POWER JACKS  
POWER Jack  
CHARGE Jack  
The scanner has two external power jacks — POWER and CHARGE. It  
is important that you understand the purpose of each jack before you  
connect any adapter to the scanner.  
9
 
The POWER jack powers the scanner and disconnects the internal bat-  
teries. You can use this jack to connect an external power source (AC  
or DC adapter), regardless of the type of batteries you install.  
The CHARGE jack supplies power to operate the scanner and also  
charges the internal batteries. Use the CHARGE jack only when you  
have installed rechargeable nickel-cadmium batteries.  
Warning: Never use the CHARGE jack when you have installed non-  
rechargeable batteries. If you try to recharge non-rechargeable batter-  
ies, they become very hot and could explode.  
Remove the plastic plug from the CHARGE jack before you use it, then  
replace the plug when you finish.  
CHARGE Jack  
USING STANDARD AC POWER  
To power the scanner from AC power, you need an AC adapter such  
as RadioShack Cat. No. 273-1665. Plug the adapter’s 3.4 mm outer di-  
ameter/1.3 mm inner diameter barrel plug into the scanner’s POWER  
jack. Then plug the adapter’s power module into a standard AC outlet.  
Warning: Do not use an AC adapter’s polarized plug with an extension  
cord, receptacle, or other outlet unless the blades can be fully inserted  
to prevent blade exposure.  
10  
 
Cautions:  
You must use an AC adapter that supplies 9 volts and delivers at  
least 300 mA. Its center tip must be set to negative and its plug  
must fit the scanner’s POWER jack. The recommended adapter  
meets these specifications. Using an adapter that does not meet  
these specifications could damage the scanner or the adapter.  
• When you finish using the AC adapter, disconnect it from the AC  
outlet first. Then disconnect it from the scanner.  
USING VEHICLE BATTERY POWER  
You can power the scanner from your vehicle’s battery power using an  
optional DC adapter, such as Cat. No. 273-1810.  
Cautions:  
You must use a DC adapter that supplies 9 volts (regulated) and  
delivers at least 300 mA of DC automotive power. Its center tip  
must be set to negative and its plug must fit the scanner’s POWER  
jack. Both of the recommended adapters meet these specifica-  
tions. Using an adapter that does not meet these specifications  
could damage the scanner or the adapter.  
To protect your vehicle’s electrical system, always plug the adapter  
into the scanner before you plug it into your vehicle’s cigarette-  
lighter socket. Always unplug the adapter from the vehicle’s ciga-  
rette-lighter socket before you unplug it from the scanner.  
1. Connect the DC adapter’s 3.4 mm outer diameter/1.3 mm inner  
diameter barrel-plug to the adapter’s cable, with the tip set to –.  
2. Set the adapter’s voltage switch to 9V.  
3. Insert the barrel plug into the scanner’s POWER jack.  
11  
 
4. Plug the other end of the adapter into your vehicle’s cigarette-  
lighter socket.  
Note: If the scanner does not operate properly when you use a DC  
adapter, unplug the adapter from the cigarette-lighter socket and clean  
the socket to remove ashes and other debris.  
CHARGING NICKEL-CADMIUM BATTERIES  
The scanner has a built-in charging circuit that lets you recharge nickel-  
cadmium batteries while they are in the scanner. To charge the batter-  
ies, remove the plug from the scanner’s CHARGE jack and connect an  
optional AC adapter or DC adapter to the jack (see “Using Standard  
AC Power” on Page 10 or “Using Vehicle Battery Power” on Page 11).  
Warning: Do not connect an adapter to the scanner’s CHARGE jack if  
you installed non-rechargeable batteries (standard, extra-life, or alka-  
line). Non-rechargeable batteries become hot and could explode if you  
try to recharge them.  
It takes about 14 to 16 hours to recharge batteries that are fully dis-  
charged. You can operate the scanner while recharging the nickel-  
cadmium batteries, but charging takes longer.  
Note: Nickel-cadmium batteries last longer and deliver more power if  
you occasionally let them fully discharge. To do this, simply use the  
scanner until it begins beeping every 15 seconds and BATT.LOap-  
pears. Then fully charge the batteries.  
Important: At the end of a rechargeable battery’s useful life, it must be  
recycled or disposed of properly. Contact your local, county, or state  
hazardous waste management authorities for information on recycling  
or disposal programs in your area. Some options that might be avail-  
able are: municipal curb-side collection, drop-off boxes at retailers such  
as your local RadioShack store, recycling collection centers, and mail-  
back programs.  
12  
 
CONNECTING THE ANTENNA  
Follow these steps to attach the supplied flexible  
antenna to the connector on the top of your scan-  
ner.  
1. Align the slots around the antenna’s connec-  
tor with the tabs on the jack.  
2. Press the antenna down over the jack and  
rotate the antenna’s base clockwise until it  
locks into place.  
Connecting an Optional Antenna  
The antenna connector on your scanner makes it easy to use the scan-  
ner with a variety of antennas. Instead of the supplied antenna, you  
can attach an external mobile antenna or outdoor base antenna (for  
example). Your local RadioShack store sells a variety of antennas.  
Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect  
an outdoor antenna. For lengths over 50 feet, use RG-8 low-loss di-  
electric coaxial cable. If your antenna’s cable does not have a BNC  
connector, you will also need a BNC adapter (available at your local  
RadioShack store).  
Warning: When you install an outdoor antenna, use extreme cau-  
tion. If the antenna starts to fall, let it go! It could contact overhead  
power lines. If the antenna touches the power line, contact with the  
antenna, mast, cable, or guy wires can cause electrocution and  
death. Call the power company to remove the antenna. Do not at-  
tempt to remove it yourself!  
13  
 
CONNECTING AN EARPHONE/  
HEADPHONES  
For private listening, you can plug an earphone or mono headphones  
(not supplied) with a 1/8-inch (3.5-mm) plug (such as Cat. No. 33-177 or  
20-210) into the jack on top of your scanner. This automatically dis-  
connects the internal speaker.  
Listening Safely  
To protect your hearing, follow these guidelines when you use an ear-  
phone or headphones.  
• Set the volume to the lowest setting before you begin listening.  
After you begin listening, adjust the volume to a comfortable level.  
• Do not listen at extremely high volume levels. Extended high-  
volume listening can lead to permanent hearing loss.  
• Once you set the volume, do not increase it. Over time, your ears  
adapt to the volume level, so a volume level that does not cause  
discomfort might still damage your hearing.  
Traffic Safety  
Do not use an earphone or headphones with your scanner when oper-  
ating a motor vehicle or riding a bicycle in or near traffic. Doing so can  
create a traffic hazard and could be illegal in some areas.  
If you use an earphone or headphones with your scanner while riding a  
bicycle, be very careful. Do not listen to a continuous broadcast. Even  
though some earphones or headphones let you hear some outside  
sounds when listening at normal volume levels, they still can present a  
traffic hazard.  
14  
 
CONNECTING AN EXTENSION SPEAKER  
In a noisy area, an optional extension speaker (such as RadioShack  
Cat. No. 21-549) or an amplified speaker (such as RadioShack Cat.  
No. 21-541), positioned in the right place, might provide more comfort-  
able listening. Plug the speaker cable’s 1/8-inch (3.5 mm) mini-plug into  
your scanner’s jack.  
USING THE BELT CLIP  
You can attach the supplied belt clip to make the scanner easier to use  
when you are on the go. Use a Phillips screwdriver and the two sup-  
plied screws to attach the belt clip to the scanner. Then slide the belt  
clip over your belt or waistband.  
Belt Clip

UNDERSTANDING YOUR SCANNER  
A LOOK AT THE KEYPAD  
Your scanner’s keys might seem confusing at first, but this information  
should help you understand each key’s function.  
SCAN — scans through the programmed channels.  
MANUAL — stops scanning and lets you directly enter a channel num-  
ber.  
LOCKOUT/S/S — lets you lock out a selected channel. Skips a specified  
frequency during limit or direct search.  
PRIORITY — sets and turns on and off priority for a particular channel.  
MON/CLR/ — accesses the ten monitor memories, clears an incorrect  
entry or enters the decimal point necessary when programming fre-  
quencies.  
WX/E (enter) — scans through the preprogrammed weather channels or  
enters frequencies into channels.  
KEYLOCK/  
— locks/unlocks the keypad to prevent accidental entries  
or turns on the display light for 15 seconds.  
PROGRAM — programs frequencies into channels.  
, LIMIT, and — searches for active frequencies.  
Number Keys — each key has a single-digit label, and keys 09 have  
a range of numbers printed above them. The single digits refer to the  
number of a channel or frequency entered. The number range (21–30,  
16  
 
for example) shows the channels that make up a memory bank. In ad-  
dition, the keypad has different functions in manual mode, scan mode,  
and program mode. See “Banks and Memories” on Page 19.  
A LOOK AT THE DISPLAY  
The display has several indicators that show the scanner’s current op-  
erating mode. A quick look at the display will help you understand how  
to operate your scanner.  
MON — appears when you listen to a monitor memory. A number  
(110) appears to the right of MONindicating which monitor memory  
you are listening to.  
BANK — shows which channel-storage banks are turned on for the  
scan mode. See “Banks and Memories” on Page 19.  
KEYLOCK— appears when you lock the keypad.  
BATT.Lo— appears when the batteries are low.  
CH— digits that precede this indicator show which of the 100 channels  
the scanner is tuned to.  
P — appears when you listen to the priority channel.  
MHz — digits that precede this indicator show which frequency the  
scanner is tuned to.  
SCAN— appears when you scan channels.  
MAN— appears when you manually select a channel.  
PGM — appears while you program frequencies into the scanner’s  
channels.  
17  
 
PRI— appears when you select the priority feature.  
L/O — appears when you manually select a locked-out channel, or  
during a search hold when the frequency is stored in search skip mem-  
ory.  
WX— appears when you scan the preprogrammed weather channels.  
and — indicate the search direction.  
SRCH— appears during a limit search, a direct search, and a weather  
band search.  
-L-— appears instead of the channel number during a limit search.  
-d-— appears instead of the channel number during a direct search.  
Hi— appears with a frequency to show the upper limit of the frequen-  
cy range to search.  
Lo— appears with a frequency to show the lower limit of the frequency  
range to search.  
-H-— appears during a limit search hold.  
-h-— appears during a direct search hold.  
Error— appears when you make an entry error.  
18  
 
BANKS AND MEMORIES  
Your scanner can store up to 110 frequencies. You store each frequen-  
cy in either a memory called a channel, or a temporary memory called  
a monitor memory. This scanner has 100 channels and ten monitor  
memories.  
CHANNEL-STORAGE BANKS  
To make it easier to identify and select the channels you want to listen  
to, channels are divided into ten channel-storage banks of 10 channels  
each. Use each channel-storage bank to group frequencies, such as  
the police department, fire department, ambulance services, or aircraft  
band (see “Guide to the Action Bands” on Page 31.  
For example, the police might use four frequencies, one for each area  
of town. You could program the police frequencies starting with Chan-  
nel 1 (Bank 1) and then program the fire department frequencies start-  
ing with Channel 11 (the first channel in Bank 2).  
MONITOR MEMORIES  
The scanner also has ten monitor memories. Use these memories to  
temporarily store frequencies while you decide whether or not to save  
them into channels. This is handy for quickly storing an active frequen-  
cy when you are searching through an entire band.  
Note: To store frequencies into a monitor memory, you must first per-  
form a limit or direct search. See “Searching For and Temporarily Stor-  
ing Active Frequencies” on Page 21.

Notes:  
• If you entered an incorrect frequency in Step 3, Errorappears  
and the scanner beeps three times. Start again from Step 3.  
Your scanner automatically rounds the entered frequency to the  
nearest valid frequency. For example, if you enter a frequency of  
151.473, your scanner accepts it as 151.475.  
5. Repeat Steps 1–4 to program more channels. Or, if you want to  
program the next channel in sequence, repeat Steps 2–4.  
To listen to a frequency you have stored, press MANUAL, the channel  
number, then MANUAL again.  
SEARCHING FOR AND TEMPORARILY  
STORING ACTIVE FREQUENCIES  
Good references for active frequencies are the RadioShack “Police  
Call,” “Aeronautical Frequency Directory,” and “Maritime Frequency Di-  
rectory.” We update these directories every year, so be sure to get a  
current copy.  
If you do not have a reference to frequencies in your area, or if you  
want to search for unlisted frequencies, use a limit search or direct  
search. See also “Guide to the Action Bands” on Page 31.  
21  
 
Limit Search  
A limit search lets you search for active frequencies between upper  
and lower limits that you set. -L-appears during a limit search.  
When you are in the search mode, MONappears and the flashing num-  
ber at the top of the display indicates the currently selected monitor  
memory. Once you have stored a frequency into that monitor memory,  
press or . The scanner shifts to the next monitor memory and re-  
starts the search mode.  
1. Press PROGRAM then LIMIT. Loappears.  
2. Enter the lower limit of the frequency range you want to search.  
3. Press E then LIMIT. Hiappears.  
Note: If the frequency you entered is not a valid frequency, Error  
appears. Enter a different frequency then repeat Step 3.

MANUALLY SELECTING A CHANNEL  
You can continuously monitor a specific channel without scanning. This  
is useful if you hear an emergency broadcast on a channel and do not  
want to miss any details — even though there might be periods of si-  
lence — or if you want to monitor a specific channel.  
Follow these steps to manually select a channel.  
1. Press MANUAL.  
2. Enter the channel number.  
3. Press MANUAL again.  
Or, if the scanner is scanning and stops at the desired channel, press  
MANUAL once. (Pressing MANUAL additional times causes your scan-  
ner to step through the channels.)  
To resume automatic scanning after manually selecting a channel,  
press SCAN.  
25  
 
SPECIAL FEATURES  
USING THE KEYLOCK  
Once you program your scanner, you can protect it from accidental  
program changes by turning on the keylock feature. In this mode, the  
only controls that operate are SCAN, MANUAL, KEYLOCK (  
), VOL-  
UME, and SQUELCH.  
Note: Turning on the keylock does not prevent the scanner from scan-  
ning channels.  
To turn the keylock on or off, turn on the scanner then hold down KEY-  
LOCK until the scanner beeps and KEYLOCKappears or disappears.  
LOCKING OUT CHANNELS  
You can increase the effective scanning speed by locking out individual  
channels that have a continuous transmission, such as a weather  
channel. To lock out a channel, manually select the channel then press  
LOCKOUT (S/S). L/Oappears.  
To remove the lockout from a channel, manually select the channel  
then press LOCKOUT. L/Odisappears.  
Note: You can manually select locked-out channels.  
To remove the lockout from all channels, follow these steps:  
1. While scanning, turn on the memory banks you want to unlock.  
2. Press MANUAL.  
3. Hold down LOCKOUT for at least 3 seconds. The scanner beeps  
twice, and all locked out memory channels in the selected banks  
are unlocked.  
26  
 
TURNING CHANNEL-STORAGE BANKS ON  
AND OFF  
You can turn each channel-storage bank on and off. When you turn off  
a bank, the scanner does not scan any of the 10 channels in that bank.  
While scanning, press the number key corresponding to the bank you  
want to turn on or off. (Press 0 to select bank 10). If the memory bank  
indicator is on, the bank is turned on and the scanner scans all chan-  
nels 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.  
Memory banks 3 and 4 are turned off  
BANK  
Notes:  
You can manually select any channel in a bank, even if the bank is  
turned off.  
You cannot turn off all banks. One bank is always active.  
SEARCH SKIP MEMORY  
You can skip specified frequencies during a limit or direct search. This  
lets you avoid unwanted frequencies or ones you have already stored  
in a channel. You can program up to 20 frequencies to be skipped into  
the scanner’s memory.  
To skip a frequency, press S/S (LOCKOUT) when the scanner stops on  
the frequency during a limit or direct search. L/O(lockout) appears the  
next time you display that frequency.  
To clear a single frequency from search skip memory so the scanner  
can stop on it during a limit or direct search, press LIMIT to hold the  
search, press or to select the frequency (where L/Oappears),  
then press S/S. L/Odisappears.  
To clear all the skip frequencies from search skip memory at once  
while searching, hold down S/S until the scanner beeps twice.  
27  
 
Notes:  
• If you program more than 20 skip frequencies, each new frequency  
replaces one you stored earlier, starting from the first stored fre-  
quency.  
You can select a skipped frequency by using or when the  
scanner is holding. L/Oappears when you select a skipped fre-  
quency.  
PRIORITY  
You can scan through channels and still not miss an important call on a  
specific channel. When a channel is selected as the priority channel  
and priority is turned on, the scanner checks that channel every 2 sec-  
onds, and stays on the channel if there is activity until the activity stops.  
PRIappears whenever the scanner is set to use priority.  
The scanner is preset to select Channel 1 as the priority channel. To  
program a different channel as the priority channel, press PROGRAM,  
the desired channel number, then PRIORITY. P appears beside the  
channel number.  
To turn on the priority feature, press PRIORITY while MANor SCANap-  
pear. To turn off the priority feature, press PRIORITY. PRIdisappears.  
Notes:  
You can select only one channel at a time as the priority channel.  
You cannot select a monitor memory when priority is turned on.  
USING THE DISPLAY BACKLIGHT  
You can turn on the display’s backlight for easy viewing in the dark.  
Press  
to turn on the display light for 15 seconds. To turn off the

light before 15 seconds elapses, press  
Note: The scanner locks the keypad (see “Using the Keylock” on  
Page 26) if you hold down . If this happens, hold down until the  
scanner beeps and KEYLOCKdisappears.

LISTENING TO THE WEATHER BAND  
The FCC (Federal Communications Commission) has allocated 11  
channels for use by the National Oceanic and Atmospheric Administra-  
tion (NOAA). We have preprogrammed your scanner with the seven  
frequencies most commonly used by NOAA.  
To hear your local forecast and regional weather information, simply  
press WX (E). Your scanner begins scanning through the weather  
band, and WXappears.  
If there is a weather broadcast in your area, your scanner stops within  
a few seconds and you hear the local weather broadcast. If the broad-  
cast is weak, you can press WX again to scan through the rest of the  
weather band.

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.  
During the summer months, you might be able to hear stations in the  
30–50 MHz range located several hundred or even thousands of miles  
away. This is because of summer atmospheric conditions. This type of  
reception is unpredictable but often very interesting!

Ham Radio Frequencies  
Ham radio operators often broadcast emergency information when oth-  
er means of communication break down. The following chart shows the  
frequencies this scanner receives that Hams normally use:  
Wavelength (meters)  
Frequency (MHz)  
10-meter  
6-meter  
2-meter  
70-meter  
29.000–29.700  
50.000–54.000  
144.000–148.000  
420.000–450.000  
Note: Your scanner cannot receive some types of transmissions on  
these bands.  
30  
 
Birdie Frequencies  
Every scanner has birdie frequencies. Birdies are signals created in-  
side the scanner’s receiver. These operating frequencies might inter-  
fere with broadcasts on the same frequencies. If you program one of  
these frequencies, you hear only noise on that frequency. If the inter-  
ference is not severe, you might be able to turn SQUELCH clockwise to  
cut out the birdie.  
The birdie frequency on this unit to watch for is 146.65 MHz.  
To find the birdies on your receiver, begin by disconnecting the anten-  
na and moving it away from the receiver. Make sure that no other near-  
by radio or TV sets are turned on near the receiver. 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.

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  
431.875 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 21.4 MHz  
(42.8)  
and subtract it from the new frequency.  
–42.8  
If the answer is the regular frequency,  
then you have tuned to an image.  
431.875  
Occasionally you might get interference on a weak or distant channel  
from a strong broadcast 42.8 MHz 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 by 1,000:  
9.62 MHz × 1000 = 9620 kHz  
To convert from kHz to MHz, divide by 1,000.  
2780 kHz ÷ 1000 = 2.780 MHz  
To convert MHz to meters, divide 300 by the number of megahertz.  
300 ÷ 7.1 MHz = 42.25 meters

TROUBLESHOOTING  
If you have problems, here are some suggestions which might help.  
PROBLEM  
POSSIBLE CAUSE  
REMEDY  
Scanner is on but  
will not scan.  
SQUELCH is not  
adjusted correctly.  
Adjust SQUELCH  
clockwise.  
Only one channel or  
no channels are  
stored.  
Store frequencies  
into more than one  
channel.  
Channels are locked  
out.  
Remove the lockout.  
Scanner is totally  
inoperative.  
No power.  
Check the batteries  
or make sure the AC  
adapter or DC  
adapter is con-  
nected properly.  
Recharge the  
rechargeable batter-  
ies or replace the  
non-rechargeable  
batteries.  
The AC adapter or  
DC adapter is not  
connected.  
Be sure the  
adapter’s barrel plug  
is fully plugged into  
the POWER jack.  
In the scan mode,  
the scanner locks  
on frequencies that  
have an unclear  
transmission.  
“Birdies.”  
Avoid programming  
frequencies listed  
under “Birdie Fre-  
quencies” on  
Page 31 or only lis-  
ten to them manu-  
ally.  
If none of these suggestions help, take your scanner to your local Ra-  
dioShack store for assistance.  
38  
 
RESETTING THE SCANNER  
If the scanner’s display does not work properly after you install batter-  
ies or connect it to power, you might have to reset the scanner.  
Caution: This procedure clears all the information you have pro-  
grammed into the scanner. Before you reset the scanner, try turning it  
off and on to see if it begins working properly.  
To reset the scanner, turn it off then turn it back on while holding down  
the 2 and 9 keys.  
39  
 
CARE AND MAINTENANCE  
Your RadioShack PRO-71 VHF/UHF/Air Handheld Scanner is an ex-  
ample of superior design and craftsmanship. The following sugges-  
tions will help you care for your scanner so you can enjoy it for years.  
Keep the scanner dry. If it gets wet, wipe it dry immedi-  
ately. Liquids might contain minerals that can corrode  
the electronic circuits.  
Use and store the scanner only in normal temperature  
environments. Temperature extremes can shorten the  
life of electronic devices, damage batteries, and distort  
or melt plastic parts.  
Keep the scanner away from dust and dirt, which can  
cause premature wear of parts.  
Handle the scanner gently and carefully. Dropping it can  
damage circuit boards and cases and can cause the  
scanner to work improperly.  
Use only fresh batteries of the required size and recom-  
mended type. Batteries can leak chemicals that damage  
your scanner’s electronic parts.  
Wipe the scanner with a damp cloth occasionally to keep  
it looking new. Do not use harsh chemicals, cleaning sol-  
vents, or strong detergents to clean the scanner.  
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.
