Your Radio Shack PRO-2040 100-
Channel Programmable Home Scan-
ner lets you in on all the action! This
scanner gives you direct access to
over 30,000 exciting frequencies that
include police and fire departments,
ambulance and transportation ser-
vices, and amateur radio. You can
select up to 100 channels to scan,
and you can change your selections
at any time.
The secret to your scanner’s ability to
scan so many frequencies is its cus-
tom-designed microprocessor — a ti-
ny, built-in computer.
Your scanner also has these fea-
tures:
H
y
perscan —scans 50 channels
per second.
H
y
persearch —searches through
frequencies at 300 steps per second
in bands that have 5 kHz steps to
help you find interesting broadcasts.
Ten 10-Channel Stora
g
e Banks —
let you store 10 channels in each of
10 banks to group frequencies so
you can easily identify calls.
Priorit
y
Channel — checks a speci-
fied channel every 2 seconds so you
do not miss important calls.
Data Detection — you can set it to
detect data signals (nonmodulated
signals such as preamble signals for
pagers) during a limit or a direct
search so it can automatically contin-
ue searching.
Monitor Memories — let you store
up to 10 frequencies you locate dur-
ing a frequency search which you
can then transfer into channels.
Search Function —searches for
new and unlisted frequencies using a
designated frequency range (limit
search) or starting from a specified
frequency (direct search).
Selectable Scan/Search Speeds
—let you select normal or hyper
scan speeds, and normal, high, or
hyper search speeds.
Manual or Scan Channel Select —
lets you manually specify a single
channel or set the scanner to auto-
matically scan all the stored chan-
nels.
Search Skip —lets you select up to
50 frequencies for the scanner to
skip during a limit or direct search, so
you can avoid unwanted frequen-
cies.

Two-Second Scan Delay — delays
scanning for 2 seconds before mov-
ing to another channel, so you can
hear more replies.
Weather Band Key —scans the
preprogrammed weather frequen-
cies to keep you informed of the most
current weather conditions.
Memory Backup —keeps the chan-
nel frequencies stored in your scan-
ner’s memory for up to 3 days during
a power loss.
Squelch Control —lets you adjust
the receiver’s sensitivity low enough
to receive weak signals or high
enough to eliminate receiver noise
when not receiving a signal.
Lock-Out Function — prevents
channels you select from being
scanned.
Backlit LCD Display —lets you
easily see the indicators on the scan-
ner’s display, even at night.
Audio Output Jack — lets you con-
nect an earphone or headphones for
private listening, or an external
speaker for listening in a remote or
noisy area.

Scanning Legally
Scannin
g
is a fun and interestin
g
hobby. You can hear police and fire depart-
ments, ambulance services,
g
overnment a
g
encies, private companies, amateur
radio services, aircraft, and military operations. It is le
g
al to listen to almost every
transmission your scanner can receive. However, there are some electronic and
wire communications that are ille
g
al to intentionally intercept. These include:
• Telephone conversations (cellular, cordless, or other private means of tele-
phone si
g
nal transmission)
•Pa
g
er transmissions
• Scrambled or encrypted transmissions
Accordin
g
to the Federal Electronic Communications Privacy Act (ECPA), as
amended, you could be fined and possibly imprisoned for intentionally listenin

PREPARATION
CONNECTING POWER
Using Standard AC Power
You can power your scanner from a
standard AC outlet using the sup-
plied AC adapter.
Warnin
g
:Do not use the AC adapt-
er’s polarized plug with an extension
cord receptacle unless the blades
can be fully inserted to prevent blade
exposure.
Cautions:
• The supplied AC adapter sup-
plies 12 volts and delivers 500
milliamps. Its center tip is set to
positive, and its plug properly fits
the scanner’s DC 12V jack.
Using an AC adapter that does
not meet these specifications
could damage the scanner or
the adapter. The scanner’s dis-
play dims if the AC adapter you
use does not provide the
required 12 volts DC.
• Be sure you connect the AC
adapter to the scanner before
you connect it to a standard AC
outlet. Then disconnect the
adapter from the AC outlet
before you disconnect it from the
scanner.
• If you have difficulty inserting the
AC adapter’s polarized plug, do
not force it. Turn it over and rein-
sert it.
1. Insert the supplied AC adapter’s
barrel plug into the scanner’s DC
12V jack.
2. Plug the adapter’s power mod-
ule into a standard AC outlet.
Memory Backup
If a power failure occurs or if the pow-
er cord is disconnected, the scan-
ner’s memory backup circuit keeps
information in memory for up to 3
days.
Note: The memory backup circuit
begins to protect the contents in
memory within a few minutes after
you plug in the scanner.
20-414.fm Page 7 Wednesday, August 4, 1999 11:12 AM

8
Using Vehicle Battery Power
To power your scanner from your ve-
hicle’s battery power, you need a DC
power cord (such as Radio Shack
Cat. No. 270-1533).
Cautions:
• Your vehicle must have a 12-volt
DC, negative-ground electrical
system.
• The recommended DC power
cord supplies 12 volts and deliv-
ers at least 500 milliamps. The
center tip on the barrel plug is
set to positive, and the plug
properly fits the scanner’s DC
12V jack. Using a DC power cord
(or adapter) that does not meet
these specifications could dam-
age the scanner or the cord (or
adapter). The scanner’s display
dims if the DC cord (or adapter)
you use does not provide the
required 12 volts DC.
• Be sure you connect the DC
cord to the scanner before you
connect it to the vehicle’s ciga-
rette-lighter plug. Then discon-
nect the cord from the vehicle’s
cigarette-lighter plug before you
disconnect it from the scanner.
Follow these steps to use vehicle
battery power.
1. Insert the barrel plug into the
scanner’s
DC 12V jack.
2. Plug the other end of the
adapter into your vehicle’s ciga-
rette-lighter socket.
Note: If the scanner does not oper-
ate properly when you use a DC cord
(or adapter), unplug the cord (or
adapter) from the lighter socket and
clean the socket to remove ashes
and other debris.

CONNECTING AN
ANTENNA
You can connect either the supplied
telescoping antenna or an optional
antenna.
Telescoping Antenna
To attach the telescoping antenna,
simply screw it into the hole on top of
your scanner.
The antenna’s length controls its
sensitivity. Adjust the length of the
telescoping antenna as follows for
the best reception.
29-54 MHz Extend all 3 seg-
ments
108-174 MHz Extend only 2 seg-
ments
406-956 MHz Collapse Fully (only
1 segment extend-
ed)
Optional Outdoor Antenna
The supplied antenna is usually ade-
quate for strong, local signals. How-
ever, for the best results in receiving
weaker, more distant signals on all
bands, you can attach an optional
outdoor antenna (not supplied), such
as a mobile, telescoping, multi-band,
or outdoor base antenna.
Warning: When installing or remov-
ing an outdoor antenna, follow all
cautions and warnings included with
the antenna.
Notes:
• This scanner uses a BNC
antenna connector. If the coaxial
cable’s connector does not fit
the ANT jack, you might also
need an adapter. Your local
Radio Shack store sells a com-
plete line of outdoor antennas,
adapters, BNC connectors, and
mounting hardware.
• Always use 50-ohm coaxial
cable to connect an outdoor
antenna. For lengths under 50
feet, use RG58 (Cat. No. 278-
1314) or RG8/M (Cat. No. 278-
1313). For lengths over 50 feet,
use RG-8, low-loss coaxial cable
(Cat. No. 278-1312).
20-414.fm Page 9 Wednesday, August 4, 1999 11:12 AM

10
For the best performance, consider
the following when deciding on an
outdoor base antenna and its loca-
tion:
• The location of the external
antenna should be as high as
possible.
• The external antenna and
antenna cable should be as far
away as possible from sources
of electrical noise (appliances,
other radios, and so on).
• The external antenna should be
vertical.
Mount the antenna following the in-
structions supplied with the antenna
and its mounting hardware, then fol-
low these steps to connect an exter-
nal antenna.
1. Route the antenna cable to the
scanner and connect it to the
ANT jack on the back of the
scanner.
Caution:
Do not route the cable
over sharp edges or moving
objects.
2. Remove the supplied antenna
from the top of the scanner.
RESETTING THE
SCANNER’S DISPLAY
If the scanner’s display locks up after
you connect a power source, follow
these steps to reset it.
1. If the scanner is off, press
POWER to turn it on.
2. Using a pointed object, such as
a straightened paper clip, press
RESET on the back of the scan-
ner. The display resets, and the
scanner turns off.
3. Press POWER to turn on the
scanner again.
20-414.fm Page 10 Wednesday, August 4, 1999 11:12 AM

11
INITIALIZING THE
SCANNER
If the scanner or its display does not
work properly even after resetting it,
follow these steps to initialize the
scanner.
Caution: Initializing the scanner
clears all the channels you stored in
memory. Initialize the scanner only
when you are sure it is not working
properly.
1. If the scanner is off, press
POWER to turn it on.
2. Press and hold ./CLEAR, then
press
RESET on the back of the
scanner using a pointed object,
such as a straightened paper
clip. The display resets, and the
scanner turns off.
3. Press POWER to turn on the
scanner.
CONNECTING AN
EARPHONE/
HEADPHONES/
EXTERNAL SPEAKER
The 1/8-inch EXT SP jack on the back
of the scanner lets you connect an
earphone, headphones, or an exter-
nal speaker.
• For private listening, connect an
earphone (Cat. No. 33-175).
• For more comfortable private lis-
tening, connect monaural head-
phones (Cat. No. 20-210).
• For listening from a remote area
or in a noisy area, connect an
extension speaker (Cat. No. 21-
549).
Note: Connecting any external de-
vice to the EXT SP jack automatically
disconnects the internal speaker.
20-414.fm Page 11 Wednesday, August 4, 1999 11:12 AM

12
Listening Safely
To protect your hearing, follow these
guidelines when you use an ear-
phone or headphones.
• Do not listen at extremely high
volume levels. Extended high-
volume listening can lead to per-
manent hearing loss.
• Set the volume to the lowest set-
ting 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 not wear an earphone or head-
phones while operating a motor vehi-
cle or riding a bicycle. This can
create a traffic hazard and is illegal in
some areas.
Even though some earphones are
designed to let you hear some out-
side sounds when listening at normal
volume levels, they still present a
traffic hazard.

17
UNDERSTANDING THE
SCANNER’S MEMORY
You can store up to 110 frequencies
into your scanner’s memory. You
store each frequency into either a
memory called a channel, or a tem-
porary memory called a monitor. This
scanner has 100 channel memories
and 10 monitor memories.
Channel-Storage Banks
To make it easier to identify and se-
lect the channels you want to listen
to, channels are divided into 10 chan-
nel-storage banks of 10 channels
each. Use each channel-storage
bank to group frequencies, such as
the police department, fire depart-
ment, ambulance services, or aircraft
(see “A Guide to the Action Bands”).
For example, the police department
might use four frequencies, one for
each side of town. You could pro-
gram the police frequencies starting
with Channel 1 (the first channel in
Bank 1) and program the fire depart-
ment starting with Channel 11 (the
first channel in Bank 2).
Monitor Memories
The scanner has 10 monitor memo-
ries. You can use these memories to
temporarily store frequencies while
you decide whether or not to store
them into channels. This is handy for
quickly storing an active frequency
when you search through an entire
band. You can manually select these
memories, but you cannot scan
them. See “Searching For and Tem-
porarily Storing Active Frequencies.”
When you are in the monitor mode,
one of the memory numbers (1-10)
appears to the right of the MON indi-
cator. The number indicates the cur-
rent monitor memory.

OPERATION
TURNING ON THE
SCANNER/SETTING
THE VOLUME AND
SQUELCH
1. Turn SQUELCH fully clockwise.
2. Press POWER to turn on your
scanner. The scanner continu-
ously scans the unlocked chan-
nels.
Note: The first time you turn on
the scanner, the channels might
not have any frequencies stored
in them, but the scanner will
continuously scan the empty
channels anyway.
3. Press MANUAL to stop the scan-
ning. The display shows the cur-
rent channel.
4. Turn VOLUME clockwise to set
the scanner’s volume about 1/4
of the way between MIN and
MAX.
5. Turn SQUELCH counterclock-
wise until you hear a hissing
noise.
20-414.fm Page 18 Wednesday, August 4, 1999 11:12 AM

19
6. Adjust VOLUME to a comfortable
level.
7. Slowly turn SQUELCH clockwise
until the hissing noise stops.
Squelch Tips:
• If the scanner picks up
unwanted or weak transmis-
sions, slightly turn SQUELCH
clockwise to decrease receiver
sensitivity.
• If the scanner does not pick up
any transmissions, slightly turn
SQUELCH counterclockwise to
increase receiver sensitivity.
FINDING BIRDIE
FREQUENCIES
Birdies are operating frequencies
generated and used inside the scan-
ner’s receiver. These operating fre-
quencies could interfere with
broadcasts on the same frequencies
and make them difficult or impossible
to receive.
These are the most common birdies
to watch for:
31.0500 MHz 134.550 MHz
127.2500 MHz 136.050 MHz
128.1875 MHz 138.050 MHz
128.2500 MHz 140.275 MHz
129.6875 MHz 144.900 MHz
132.0500 MHz 171.250 MHz
132.2625 MHz
If you store one of these frequencies
into a channel, you might hear only
noise when the scanner stops on that
frequency. If the interference is not
severe, you might be able to turn
SQUELCH clockwise to cut out the
birdie.
To find your scanner’s specific bird-
ies:
1. Disconnect the antenna and
move it away from the scanner.
Note: Make sure that no other
nearby radios or TVs are turned
on.
2. Search every frequency band
from its lowest frequency to the
highest (see “Searching For and
Temporarily Storing Active Fre-
quencies”).
If searching stops (as if the scanner
had found a signal) but there is no
sound, that frequency might be a
birdie.
For future reference, record all the
birdies in your particular scanner.
20-414.fm Page 19 Wednesday, August 4, 1999 11:12 AM

20
MANUALLY STORING
FREQUENCIES IN
CHANNELS
You can manually store up to 100 fre-
quencies into your scanner’s chan-
nels. Radio Shack sells some good
references for active frequencies,
such as “Police Call Radio Guide In-
cluding Fire and Emergency Servic-
es,” “Official Maritime Frequency
Directory” and “Official Aeronautical
Frequency Directory.”
Radio Shack updates these directo-
ries every year, so be sure to get a
current copy. Ifyou do not have aref-
erence to frequencies in your area,
you can use a limit or direct search to
find a transmission.
Follow these steps to manually store
frequencies.
1. Press MANUAL to stop the scan-
ning.
2. Enter the channel number where
you want to store a frequency.
3. Press PGM. 000.0000MHz
PROGRAM, BANK, the bank
number and the selected chan-
nel number appear on the dis-
play.
4. Enter the frequency you want to
store, including the decimal
point.
Notes:
• Frequencies are separated
from each other in the follow-
ing steps:
• When you enter a frequency,
the scanner automatically
rounds it to the nearest valid
number. For example, if you
enter the frequency 151.473,
your scanner rounds it up to
151.475.
Frequencies Steps
29.0-108.0 MHz 5 kHz
108-136.975 MHz 12.5 kHz
137.0-300.0 MHz 5 kHz
300-3000 MHz 12.5 kHz
