Care and Maintenance
Faxback Doc. # 38902
Your Radio Shack PRO-2041 400-Channel Programmable Home Scanner is an
example of superior design and craftsmanship. The following suggestions
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 immediately.
Liquids can contain minerals that can corrode the electronic circuits.
Handle the scanner gently and carefully. Dropping it can damage
circuit boards and cases and can cause the scanner to work improperly.
Use and store the scanner only in normal temperature environments,
Temperature extremes can shorten the life of electronic devices and
distort or melt plasti c parts.
Keep the scanner away from dust and dirt, which can cause premature
wear of parts.
Wipe the scanner with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean th e 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 operating as
it should, take it to your local Radio S hack store for assistance .

Features
Faxback Doc. # 38896
Your new Radio Shack PRO -2041 400-Channel Programmable Home Scanner gives
you direct access to over 32,000 exciting frequencies, including police
and fire departments, ambulance services, and amateur radio services.
You can select up to 400 channels to scan, and you can change your
selection at any time.
The secret to your scanner's ability to scan so many frequencies is its
custom-designed microprocessor - a tiny, built-in computer.
Your scanner has there special features:
Hyperscan - lets you scan up to 25 channels
per second and search up to 50
steps per seconds.
Triple Conversion Superheterodyne - virtually eliminates any
Receiver
interference from intermediate
frequency (IF) images, so you hear
only the frequency you select.
17 Preprogrammed Search Bands - let you search for transmissions
within preset frequency ranges, so
you can find interesting
frequencies more quickly.
40 Monitor Memories - let you temporarily save up to
40 frequencies located during a
frequency search, so you can move
selected frequencies to channel
storage later.
Direct Frequency Search - lets you search for new and
unlisted frequencies starting
from a specified frequency.
Limit Frequency Search - lets you search for new and
unlisted frequencies within the
preset frequency ranges or your
own programmed frequency ranges in
the 10 search banks.
Eleven Preprogrammed Weather - keep you informed abo ut current
Frequencies
weather conditions.
Ten Channel -Storage Banks - let you store 40 channels in each
bank to group channels so calls
are easier to identify.
Sort - lets you move frequencies you
stored in a bank into consecutive
order. This makes it easy for you
to identify the frequencies you
have stored.
Auto Store - quickly finds and automatically
stores active frequencies into
channels.
Duplicate Frequency Check - automatically notifies you if you
are about to store a frequency you
have already stored, to help avoid
wasting storage space.
Memory Backup - keeps the frequencies stored in
memory during a power loss.
Ten Priority Channels - let you set the scanner so it
checks the next priority channel,
in order, every 2 seconds, so you
do not miss important calls.
Two-Second Scan Delay - delays scanning for about 2 seconds
before moving to another channel
or frequency, 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.
Liquid Crystal Display - makes it easy to view and change
programming information.
Backlit Display - makes the scanner easy to read
in low light conditions.
Two Power Options - let you power the scanner from
standard AC power (with the
supplied AC power cord) or your
vehicle's battery (with an optional
DC cigarette -lighter power cord).
Frequency Data Loading - lets you program the scanner
with frequencies store d in a
personal computer. You need a
personal computer and a data
interface kit (available through
your local Radio Shack store) to use
this feature.
Your PRO-2041 scanner can receive all of these frequencies:
29-54 MHz (10-Meter Amateur Radio, VHF Lo, 6 -Meter Amateur Radio)
108-136.975 MHz
(Aircraft)
137-174 MHz (Government, 2 -Meter Amateur Radio, VHF Hi)
380-512 MHz (Military Aircraft, UHF Lo, 70 -Centimeter Amateur Radio,
UHF "T" Band, Government)
806-824 MHz (UHF Public Service)
849-869 MHz (UHF Hi)
894-960 MHz (UHF Hi, 33-Centimeter Amateur Radio)
For breakdown of the frequency ranges in the 17 preprogrammed search
bands, see "Preparation," Faxback Doc. # 38897.
In addition, your scanner is preprogrammed with the following weather
service frequencies:
161.6500

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 might be able to turn SQUE LCH clockwise to cut out the
birdie.

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.

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, multiple the number of megahertz by 1,000:
30.62 (MHz) x 1000 = 30,620 kHz
To convert from kHz to MHz, divide the number if kilohertz by 1,000:
127,800 (kHz) + 1000 = 127.8 MHz
To convert MHz to meters, divide 300 by the number of megahertz:
300 + 50 MHz = 6 meters

Faxback Doc. # 38898
TURNING ON THE SCANNER/SETTING VOLUME AND SQUELCH
NOTE:
Make sure the scanner's antenna is connected before you turn
it on.
1.
Turn SQUELCH fully counterclockwise.
2.
Turn OFF/VOLUME clockwise until it clicks and you hear a hissing
sound.
3.
Turn SQUELCH clockwise, then leave it set to a point just after the
hissing sound stops.
If the scanner automatically starts scanning channels, press MANUAL
to stop scanning.
NOTE:
If you have not stored frequencies into any channels (see
"Storing Active Frequencies"), the scanner does not scan.
If the scanner picks up unwanted, partial, or very weak
transmissions, turn SQUEL CH clockwise to decrease the scanner's
sensitivity to these signals. If you want to listen to a weak
or distant station, turn SQUELCH counterclockwise. (Also see
"Special Features," Faxback Doc. # 38899 for more informati on
about adjusting the scanner's sensitivity).
If SQUELCH is adjusted so you always hear a hissing sound, the
scanner does not scan properly.
STORING ACTIVE FREQUENCIES
You can store frequencies into channels using any of these methods:
Manual storage
Auto storage
Band, limit, or direct search
Good references for active frequencies are Radio Shack's "Police Call
Radio Guide Including Fire and Emergency Services," "Aeronautical
Frequency Directory," and "Maritime Frequency Directory." We update
these directories every year, so be sure to get a current copy.
See
also "General Guide to Scanning," Faxback Doc. # 38900.
If you do not have a reference to frequencies in your area, f ollow the
steps in "Automatically Storing Frequencies," "Band Search," "Limit
Search,"
or "Direct Search from the Displayed Frequency" to search for
transmissions.
Manually Storing Frequencies
If you know a frequency you want to store, you can store it manually.
1.
Press PROGRAM.
2.
Use the number keys to enter the channel number where you want to
store the frequency, then press PROGRAM again.
3.
Use the number keys to enter the frequency you want to store into
that channel (including the decimal point).
4.
Press ENTER to store the frequency.
NOTES:
PROGRAM appears.
If you entered an invalid frequency in Step 3, the scanner
beeps and displays the channel number and Error. Simply
repeat Steps 3 and 4.
Your scanner automatically rounds the entered frequency down
to the closest valid frequency. For example, if you try to
enter 151.4730, your scanner accepts it as 151.4700.
If you entered a frequency that is alre ady stored in another
channel, the scanner beeps three times and displays the lowest
channel number where the lowest channel number where the
frequency is already stored, and -DUPL- then the frequency
flashes at the channel where you tried to store it. If you
want to store the frequency anyway, press ENTER again.
If you find that you entered a wrong frequency after you press
ENTER, you can change it to the correct frequenc y by following
these steps.
5.
a.
Press ENTER.
One of the frequency's digits flashes.
b.
Repeatedly press UP ARROW and DOWN ARROW until the digit
you want to change flashes.

currently selected bank number flash.
When the scanner finds an active frequency , it stores the frequency in
the channel number displayed to the left of CH, then continues
searching for more active frequencies and storing them in any sub sequent empty channels. When the scanner fills all channels within
the selected banks, it beeps rapidly and displays the last frequency
stored and the number of the channel where it was stored.
NOTES:
During auto store, you can manually change the receiver mode.
To pause auto store, pre ss AUTO. The scanner displays the
last channel number where a frequency was stored, or - - - - if no frequencies are stored. To continue auto store, press
UP ARROW or DOWN ARROW.

including interference that may cause undesired o peration.
SCANNING LEGALLY
Your scanner covers frequencies used by many different groups including
police and fire departments, ambulance services, government agencies,
private companies, amateur radio services, military operations, pager
services, and wireline (telephone and telegraph) service providers.
It is
legal to listen to almost every transmission your scanner can receive.
However, there are some transmissions you should never intentionally
listen to. These include:
Telephone conversations (either, cellular, cordless, or other private
means of telephone transmission)
Pager transmissions
Any scrambled or encrypted transmissions
According to the Electronic Communications Privacy Act (ECPA), you are
subject to fines and po ssible imprisonment for intentionally listening
to, using, or divulging the contents of such a transmission unless you
have the content of a party to the communication (unless such activity
is otherwise illegal). We encourage responsible, legal scanner us e.

POWER SOURCES
You can power your scanner from either of these sources:
Standard AC power
Vehicle battery power using an optional DC cigarette -lighter power
cord
NOTE:
If the scanner stops working properly after connecting it to power,
try resetting it.
The memory backup circuit begins to function a few minutes after
you supply power to the scanner. How long the scanner will
maintain channels stored in memory depends on how long power has
been supplied to the scanner. If power is continuously supplied
to the scanner for at least 4 days, the memory backup circuit
maintains the channels stored in memory for up to 3 months.
Using Standard AC Power
Plug the scanner's power cord into a standard AC outlet.
WARNING:
Do not use the scanner's polarized plug with an extension cord,
receptacle, or other outlet unless the blades can be fully
inserted to prevent blades can be fully inserted to prevent
blade exposure.
Using Vehicle Battery Power
If your AC power does not work in an emergency, you can power your scanner
from your vehicle's cigarette -lighter socket with an optional DC
cigarette-lighter power cord such as Cat. No. 270 -1533 (not supplied).
To connect an optional DC cigarette-lighter power cord, insert its barrel
plug into the DC 13.8V jack on the back of the scanner, then plug the
power cord into your vehicle's cigarette -lighter socket.
Cautions:
If you use a DC cigarette -lighter power cord with the s canner, it must
supply at least 1 amp of vehicle power. Its center tip must be set to
positive, and its plug must correctly fit the DC 13.8 V jack on the
back of the scanner. The recommended power cord meets these
specifications. Using a po wer cord that does not meet these
specifications could damage the scanner or the power cord.
To protect your vehicle's electrical system, always plug the power cord
into the scanner before you plug it into your vehicle's cigarette lighter
socket. Always unplug the power cord from the vehicle's
cigarette-lighter socket before you unplug it from the scanner.
Notes:
Mobile use of this scanner is unlawful or requires a permit in some
areas. Check the laws in your area.
If the scanner does not operate properly when you connect a DC power
cord, unplug the power cord from the cigarette -lighter socket and clean
the socket to remove ashes and other debris.
CONNECTING THE ANTENNA
The supplied telescoping antenna helps your scanner receive strong local
signals. To install the antenna, screw it clockwise into the hole on the
scanner's top.
The scanner's sensitivity depends on the antenna's length and various
environmental conditions. For the best reception of the trans missions you
want to hear, adjust the antenna's length.
Frequency
Antenna Length
29-174 MHz
Extend Fully
380-512 MHz
Extend 2 segments
806-960 MHz
Collapse fully (1 segment only)
Connecting an Optional Antenna
The ANT jack on the back of the scanner makes it easy to use the scanner
with a variety of antennas. Instead of the supplied antenna, you can
attach a different one, such as an external mobile antenna or outdoor base
station antenna. Your local RadioShack store sells a variety of antennas.
When deciding on an antenna and its location, consider the following:
The location of the antenna should be 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.
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 dielectric
coaxial cable. If the coaxial cable's connector does not fit in the ANT
jack, you might also need a PL -259-to-BNC antenna plug adapter, such as
Cat. No. 278-120. Your local RadioShack store carries a wide variety of
coaxial antenna cable and connectors.
Follow the installation instructions supplied with the antenna, route the
antenna cable to the scanner, then connect it to the ANT BNC -type jack on
the back of the scanner.
Warning:
Use extreme caution when installing or removing 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 antenn a, mast, cable, or guy wires can
cause electrocution and death. Call the power company to remove
the antenna. Do not attempt to do so yourself.
Caution:
Do not run the cable over sharp edges or moving objects.
CONNECTING AN EARPHONE/HEADPHONES
For private listening, you can plug an earphone or mono headphones (such
as Cat. No. 33-175 or 20-210) into the headphones jack on the front of
your scanner.
This automatically disconnects the internal speaker.
Listening Safely
To protect your hearing, follow these guidelines when you use an earphone
or headphones:
Do not listen at extremely high volume levels.
listening can lead to permanent hearing loss.
Extended high-volume
Set the volume to the lowest sett ing before you begin listening.
After you begin listening, adjust the volume to a comfortable level.
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 mot use an earphone of headphones with your scanner when operating a
motor vehicle 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 operating
a motor vehicle, be very careful. Do not listen to a continuous
broadcast. Even though some earphones/headphones let you hear some
outside sounds when listening at normal volume level s, they still can
present a traffic hazard.
CONNECTING AN EXTENSION SPEAKER
In a noisy area, an extension speaker (Cat. No. 21 -549) or an amplified
speaker (Cat. No. 21-541) might provide more comfortable listening.
Plug the speaker cable's 1/8 -inch mini-plug into the EXT SPKR jack on the
back of your scanner.

the scanner to scan those frequencies.
A frequency is the turning location of a station (expressed in kHz or
MHz). To find active frequencies, you can use the search function to
search bands, which are preset ranges of frequencies.
When you find a frequency, you can store it into a permanent memory
location called a channel, which is grouped with your other channels
in a channel-storage bank. You can then scan the channel -storage banks
to see if there is activity on the frequencies stored there. Each time
the scanner finds an active frequency, it stays on that channel until the
transmission ends.
Another option is to store the frequency into a temporary memory location
called a monitor memory until you decide to move it to a channel.
Just keep in mind - you search frequencies and scan channels.

You can search these bands to quickly find active frequencies you
might want to store into the scanner's channels. For example, if you
wanted to search for transmissions between pilots and the control tower at
an air show, you could search only the search bands where you are most
likely to hear the transmissions (4 and 7).
NOTES:
The scanner can search for transmissions on fre quencies that are
not stored in any of the search bands.
The actual search range of Band 04 is 108 -136.975 MHz.
The frequencies in the scanner's search bands are preset.
cannot change them.
You
"General Guide to Scanning," Faxback Doc. # 38900 lists other
frequency ranges and the broadcasts you are likely to hear on those
frequencies.
Channel-Storage Banks
To make it easier to identify and select the channels you want to listen
to, channels are divided into 10 channel -storage banks (1-10) of 40
channels each. You can use each channel -storage bank to group
frequencies, such as those used by the police department, fire department,
ambulance services, and aircraft.
For example, there might be three or four police departments in your
area, using several different frequencies. Additionally, there might
be other law enforcement agencies such as state police, county sheriffs,
or SWAT teams that use their own frequencies. You could program all
law enforcement frequencies starting with Channel 1 (the first channel
in Bank 1), then program the fire department, paramedic, and other public
safety frequencies starting with Channel 41 (the first channel in Bank 2).
Monitor Memories
The scanner also has 40 monitor memories that you can use to temporarily
store frequencies while you decide whether to save them into channels.
This is handy for quickly storing an active frequency when you are
searching through an entire band.
You can only store a frequency into a monitor memory during a band, limit,
or direct search. See "Operation," Faxback Doc. # 38898.
You can select monitor memories manually, but you cannot scan them .

Special Features
Faxback Doc. # 38899
USING THE DELAY FEATURE
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 scanner stops o n the channel or frequency,
DELAY appears and the scanner continues to monitor the channel/frequency
for 2 seconds after the transmission 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.
If the desired channel is not selected, manually select the channel
then press DELAY.
If the scanner is searching, press DELAY during the search. DELAY
appears and the scanner automatically adds a 2 -second delay to every
transmission it stops on.
To turn off delay, press DELAY when DELAY is displayed.
ATTENUATING RECEPTION
To reduce interference or noise caused by signals from a strong local
broadcaster, you can reduce the scanner's sensitivity to signals by
setting the ATT (attenuate) switch on the back of the scanner. Switch
ATT to 10 dB to reduce the scanner's sensitivity, or to 0 dB to receive
the signal without attenuation.
If you switch ATT to 10 dB, your scanner might not receive weak signals.
LOCKING OUT CHANNELS AND FREQUENCIES
You can scan existing channels or search frequencies faster by locking
out channels or frequencies that have a continuous transmission, such as
a weather channel. You can lock out as many as 400 channels and 200
frequencies during a search.
To lock out a channel while scanning, press L/OUT when the scanner stops
on the channel. To lock out a channel manually, select the channel then
press L/OUT until L/O UT appears.
NOTES:
You can delete all the frequencies stored in locked -out channels
within a bank.
You can still manually select locked -out channels.
To remove the lockout from a channel, manually select the channel and
press L/OUT until L/OUT disappears.
To lock out a frequency during a band, limit, or direct search, press
L/OUT when the scanner stops on the frequency. The scanner locks out
the frequency, then continues searching.
NOTES:
The scanner does not store locked -out frequencies during a search.
If you try to lock out more than 200 frequencies, L -FULL appears.
Follow these steps to remove the lock -out from a frequency.
1.
Press BAND or LIMIT or DIRECT/.to start a search .
2.
Press L/OUT REVIEW.
3.
Repeatedly press UP ARROW or DOWN ARROW until the frequency you want
to remove the lockout from appears.
4.
Press L/OUT.
disappears.
L -r appears.
The frequency you want to remove the lockout from
If there is another locked-out frequency, it appears. If there are
no more locked-out frequencies, the scanner continues searching.
Reviewing Locked-Out Channels/Frequencies
To review the channels you locked out, press MANUAL, then repeatedly
press L/OUT REVIEW. As you press L/OUT REVIEW, the scanner displays
all locked-out channels.
To review the frequencies you locked out, press BAND, LIMIT, or DIRECT/.
to start a search, then press L/OUT REVIEW. L/OUT REVIEW L/r appears.
As you press UP ARROW or DOWN ARROW, the scanner displays all locked -out
frequencies.
USING THE PRIORITY FEATURE
The priority feature lets you scan channels and still not miss important
or interesting calls on the priority channels. You can program up to 10
frequencies as the priority channels. When you turn on the priority
feature, as the scanner scans channels. It checks one of the priority
channels every 2 seconds for activity.
NOTE:
You can lock out priority channels. If you lock out all priori ty
channels, the scanner displays PCH ALL -OFF when you lock out the
last channel.
Follow these steps to store frequencies in the priority channels.
1.
Press PROGRAM.
2.
Use the number keys to enter the priority channel number (1 -10)
where you want to store the frequency, then press PRIORITY.
3.
Use the number keys to enter the frequency you want to store into
that channel.
4.
Press ENTER to store the frequency.
NOTES:
If you entered an invalid frequency in Step 3, the scanner
beeps and displays Error. Simply repeat Steps 3 and 4.
Your scanner automatically rounds the entered frequency down
to the closest valid frequency.
If you enter a frequency that is already stored in another
channel, the scanner beeps three times and displays the lowest
channel number where the frequency is already stored, and
-dUPL- briefly flashes. Then P and th e channel number
appear and the frequency flashes. If you want to store the
frequency anyway, press ENTER again.
5.
Repeat Steps 2-4 to store more frequencies into the priority channels
(up to 10 channels).
To turn on the priority feature, press PRIORITY when the scanner is in
the scan or manual mode. Pri -On- appears. The scanner checks a
priority channel every 2 seconds. It stays on a priority channel if there
is activity, and P and the priority channel number appear alo ng with the
priority frequency.
To turn off the priority feature, press PRIORITY . P, the priority channel
number, and the frequency disappear.
Locking Out Priority Channels
1.
Press PROGRAM.
2.
Repeatedly press PRIORITY to select the priority channel you want
to lock out.
3.
Press L/OUT.
NOTE:
If you have programmed only one priority channel. PCH ALL-OFF
appears.
CHANGING THE AM/FM RECEIVE MODE
The scanner is preset to t he most common AM or FM receive mode for each
frequency range. The preset modes are:
Frequency Band
(MHz)
Receive
Mode
29.0000 - 54.0000
108.0000 - 136.9750
137.0000 - 174.0000
380.0000 - 512.0000
806.0000 - 960.0000
FM
AM

The preset mode is correct in most cases. However, some amateur radio
broadcasts do not operate in the preset mode. If you try to listen to a
broadcast when the scanner is not set to the correct receive mode, the
broadcast might sound weak or distorted.
To change the mode, press AM/FM. AM or FM blinks to indicate that
the displayed receive mode has been changed from the preset mode.
NOTE:
If you change any frequency band's receive mode during a search,
the scanner no longer uses any of the preset modes. Instead, the
scanner uses the selected mode to search for frequencies in all
bands.
To return to the default settings, hold down CLEAR, then press
CLEAR, then press AM/FM.
TURNING THE KEY TONE OFF AND ON
Each time you press any of the scanner's keys, 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 OFF/VOLUME counterclockwise until it clicks
to turn it off.
2.
While you hold down 2 and ENTER, turn on the scanner.
