cordless, or other private means
of telephone signal transmission)
FCC NOTICE
Your scanner might cause TV or radio
interference even when it is operating
properly. To determine whether your
scanner is causing the interference,
turn off your scanner. If the interfer-
ence goes away, your scanner is
causing it. Try to eliminate the interfer-
ence by:
• pager transmissions
• any scrambled or encrypted trans-
missions
According to the Electronic Communi-
cations Privacy Act (ECPA), you are
subject to fines and possible imprison-
ment for intentionally listening to, us-
ing, or divulging the contents of such a
transmission unless you have the con-
sent of a party to the communication
(unless such activity is otherwise ille-
gal).
• moving your scanner away from
the receiver
• connecting your scanner to an
outlet that is on a different electri-
cal circuit from the receiver
• contacting your local RadioShack
store for help
This scanner has been designed to
prevent reception of illegal transmis-
sions. This is done to comply with the
legal requirement that scanners be
manufactured so as to not be easily
modifiable to pick up those transmis-
sions.
If you cannot eliminate the interfer-
ence, the FCC requires that you stop
using your scanner.
SCANNING LEGALLY
Do not open your scanner’s case to
make any modifications that could al-
low it to pick up transmissions that it is
not legal to listen to. Doing so could
subject you to legal penalties.
Your scanner covers frequencies
used by many different groups includ-
ing police and fire departments, ambu-
lance services, government agencies,
private companies, amateur radio ser-
vices, military operations, pager ser-
vices, 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:
We encourage responsible, legal
scanner use.

PREPARATION
This scanner is designed for use in the
home as a base station. You can
place it on any flat surface such as a
desk, shelf, or table.
The scanner’s sensitivity depends on
the antenna’s length and various envi-
ronmental conditions. For the best re-
ception of the transmissions you want
to hear, adjust the antenna’s length.

CONNECTING AN
ANTENNA
Connecting an Outdoor
Antenna
Connecting the Supplied
Antenna
Instead of the supplied antenna, you
can connect an outdoor base-station
antenna (not supplied) to your scan-
ner. Your local RadioShack store sells
a variety of antennas. Choose the one
that best meets your needs.
You must install an antenna before
you can operate the scanner.
The supplied telescoping antenna
helps your scanner receive strong lo-
cal signals. To install the antenna,
thread it clockwise into the hole on the
scanner’s top.
When deciding on a base-station an-
tenna and its location, consider these
points:
• The antenna should be as high as
possible on the house.
• The antenna and its cable should
be as far as possible from sources
of electrical noise (appliances,
other radios, etc.).
• The antenna should be vertical for
the best performance.

20-419.fm Page 8 Wednesday, March 24, 1999 2:43 PM
To connect an optional base-station
antenna, first remove the supplied an-
tenna from the scanner. Always use
50-ohm coaxial cable, such as RG-58
or RG-8, to connect the base-station
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, you might also
need an antenna plug adapter such as
RadioShack Cat. No. 278-208. Your
local RadioShack store carries a wide
variety of coaxial antenna cable and
connectors.
CONNECTING POWER
The scanner’s supplied AC adapter
lets you power the scanner from a
standard AC outlet. To connect power
to the scanner, insert the AC adapter’s
barrel plug into the AC 10V jack on the
back of the scanner, then plug the AC
adapter into a standard AC outlet.
Once you choose an antenna, follow
the mounting instructions supplied
with the antenna. Then route the an-
tenna’s cable to the scanner and con-
nect the cable to the ANT jack on the
back of the scanner.
Warning: 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 ex-
posure.
Cautions:
You must use a Class 2 pow-
er source that supplies 10

volts AC and delivers at least
300 mA. Its plug must fit the scanner's
AC 10V jack. The supplied adapter
meets these specifications. Using an
adapter that does not meet these
specifications could damage the scan-
ner or the adapter.
• Do not run the cable over sharp
edges or moving parts that might
damage it.
• Do not run the cable next to power
cables or other antenna cables.
• Follow all cautions and warnings
included with your antenna.

Listening Safely
To protect your hearing, follow these
guidelines when you use an earphone
or headphones.
• Set OFF/VOLUME to the lowest
setting before you begin listening.
After you put on the earphone or
headphones, adjust OFF/VOLUME
to a comfortable level.
• Do not listen at extremely high
volume levels. Extended high-vol-
ume listening can lead to perma-
nent hearing loss.
• Once you set OFF/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.

UNDERSTANDING BANKS AND BANDS
You can store frequencies into either
MONITOR MEMORIES
a permanent memory location called a
channel, or a temporary memory loca-
tion called a monitor memory. You can
store up to 90 channels and up to 3
monitor memories.
Monitor memories are temporary stor-
age areas where you can store up to
three frequencies during a search
while you decide whether to save
them into channels. You can manually
select and listen to monitor memories.
Your scanner also has eight frequency
bands, each covering a specific range
of frequencies you can search.
FREQUENCY BANDS
CHANNEL-STORAGE
BANKS
Your scanner has eight frequency
bands, each covering a specific range
of frequencies. You can search these
bands for specific broadcasts by re-
peatedly pressing BAND until the
scanner displays the band you want.
To make it easier to identify and select
the frequencies you want to listen to,
the scanner’s channels are divided
into 3 channel-storage banks (1–3) of
30 channels each. You can use each
channel-storage bank to group fre-
quencies, such as those used by the
police department, fire department,
ambulance services, and amateur ra-
dio operators (see “Guide to the Ac-
tion Bands” on Page 28).
For example, you can search through
all frequencies between 29.000 and
54.000 MHz for specific broadcasts by
repeatedly pressing BAND until 29-
54appears on the display. The scan-
ner then automatically searches the
frequencies in that band.
For example, there might be three or
four police departments in your area,
each using several different frequen-
cies. 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 enforce-
ment frequencies starting with Chan-
nel 1 (the first channel in Bank 1), then
program the fire department, para-
medic, and other public safety fre-
quencies starting with Channel 31 (the
first channel in Bank 2).

Notes:
• Your scanner searches at the preset frequency step rate (5 or 12.5 kHz) for
each frequency. You cannot change the frequency step rate.
• The scanner displays the nearest 1 kHz step. For example, if you tune to
406.1125, the scanner displays 406.112.
• While searching through a frequency band, you might hear a frequency you
want to store. You can store any frequency into a monitor memory.
• You cannot change or delete any of the frequencies in the frequency bands.

MANUALLY STORING
FREQUENCIES INTO
CHANNELS
CH
If you know a frequency you want to
store, you can store it manually into a
channel.
Good references for active frequen-
cies are RadioShack’s “Police Call
Radio Guide Including Fire and Emer-
gency Services,” “Aeronautical Fre-
quency Directory,” and “Maritime
Frequency Directory.” We update
these directories every year, so be
sure to get a current copy. See also
“Guide to the Action Bands” on
Page 28 in this manual.
4. Using the number keys, enter the
frequency you want to store into
that channel, including the deci-
mal point.
Note: Your scanner automatically
rounds the entered frequency up
to the closest valid frequency. For
example, if you try to enter a fre-
quency of 151.473, your scanner
accepts it as 151.475.
Note: If you do not have a reference
to frequencies in your area, follow the
steps in “Searching For and Tempo-
rarily Storing Active Frequencies” on
Page 19 to search for transmissions.
5. Press E to store the frequency. If
the channel was locked out, the
lockout is removed.
Follow these steps to manually store a
frequency into a channel.

SPECIAL FEATURES
To turn off delay on any channel or
frequency, select that channel or fre-
quency then press DELAY. DLYdisap-
pears.
DELAY
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 fre-
quencies. Then, when the scanner
stops on the channel or frequency,
DLY appears on the display and the
scanner continues to monitor the
channel/frequency for 2 seconds after
the transmission stops before it re-
sumes scanning or searching.
SKIPPING
FREQUENCIES/
CHANNELS
You can scan channels and search for
frequencies faster by skipping ones
that have a continuous transmission,
such as a weather channel. You can
skip up to all 90 channels while scan-
ning or up to 20 frequencies during a
band or direct search.
You can program a 2-second delay in
any of the following ways:
• If the scanner is scanning and
stops on an active channel,
quickly press DELAY before it
starts to scan again.
To skip a channel/frequency while
scanning or searching, press S/S-
LOCKOUT when the scanner stops on
it.
CH
Notes:
• If the desired channel is not
selected, manually select the
channel then press DELAY.
• If you skip more than 20 search
frequencies, each new frequency
replaces an earlier one, starting
from the first stored frequency.
• If the scanner is searching, press
DELAY during the search. DLY
appears on the display and the
scanner automatically adds a 2-
second delay to every transmis-
sion it stops on.
• You can manually select skipped
frequencies after you press HOLD
to stop a search. The scanner dis-
plays L/O when you select a
skipped frequency.

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.
HAM RADIO FREQUENCIES
Ham radio operators often broadcast emergency information when other means of
communication break down.
The following chart shows the voice frequencies that you can monitor:
Wavelength
Voice (MHz)
(Meters)
10-meter

BIRDIE FREQUENCIES
UNITED STATES
BROADCAST BAND
Every scanner has birdie frequencies.
Birdies are signals created inside the
scanner’s receiver. These operating
frequencies might interfere with broad-
casts on the same frequencies. If you
program one of these frequencies, you
hear only noise on that frequency. If
the interference is not severe, you
might be able to turn SQUELCH clock-
wise to cut out the birdie.
In the United States, there are several
broadcast bands. The standard AM
and FM bands are probably the most
well known. There are also four televi-
sion audio broadcast bands — the low-
er three transmit on the VHF band and
the fourth transmits on the UHF band.
You can use your scanner to monitor
the 470-512 MHz range of the UHF
band.
The birdie frequency to watch for with
this scanner is 489.25 MHz.
To find the birdies in your scanner, be-
gin 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 scan-
ner. Use the search function and
search every frequency range from its
lowest frequency to the highest. Occa-
sionally, 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 list-
ed. It might be what is known as an image frequency. For example, you might find
a service that regularly uses a frequency of 431.975 also on 474.775.
To see if it is an image, do a little math.
Note the new frequency.
Double the intermediate frequency of 21.4 MHz (42.800)
and subtract it from the new frequency.
474.775
–42.800
431.975
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 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 the number of megahertz by 1,000:
9.62 (MHz) × 1000 = 9620 kHz
To convert from kHz to MHz, divide the number of kilohertz 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

CARE AND MAINTENANCE
Your RadioShack PRO-2049 90-Channel Programmable Home Scanner is an ex-
ample 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
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 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 cir-
cuit boards and cases and can cause the scanner to work improperly.
Wipe the scanner with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong deter-
gents to clean the scanner.
Modifying or tampering with the scanner’s internal components can cause a mal-
function and might invalidate its warranty and void your FCC authorization to oper-
ate it. If your scanner is not performing as it should, take it to your local
RadioShack store for assistance.
