SCANNING LEGALLY  
Your scanner covers frequencies used by many different groups including police  
and fire departments, ambulance services, government agencies, private com-  
panies, 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 signal transmission)  
• Pager transmissions  
• Any scrambled or encrypted transmissions  
According to the Electronic Communications Privacy Act (ECPA), you are sub-  
ject to fines and possible imprisonment for intentionally listening to, using, or di-  
vulging the contents of such a transmission unless you have the consent of a  
party to the conversation (unless such activity is otherwise illegal). We encour-  
age responsible, legal scanner use.  
Note: Mobile use of this scanner is unlawful or requires a permit in some areas.

PREPARATION  
Your scanner’s display is protected  
during shipment by a piece of blue  
film. Peel off this film before you use  
the scanner.  
• 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.  
CONNECTING POWER  
• If you have difficulty inserting the  
AC adapter’s polarized plug, do  
not force it. Turn it over and rein-  
sert it.  
Note: If a power failure occurs or if  
the DC cigarette-lighter power cable  
or AC adapter is disconnected, the  
scanner’s memory backup circuit  
keeps information in memory for up  
to 3 days.  
1. Insert the supplied AC adapter’s  
barrel plug into the scanner’s DC  
12V jack.  
Using Standard AC Power

You can power your scanner from a  
standard AC outlet using the sup-  
plied AC adapter.  
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  
exposure.  
2. Plug the adapter’s power mod-  
ule into a standard AC outlet.  
ANT  
EXT SP  
DC 12V  
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.  
Using Vehicle Battery Power  
To power your scanner from your ve-  
hicle’s cigarette-lighter socket, you  
need a DC cigarette-lighter power  
cable such as Cat. No. 270-1533).  
8
 
Cautions:  
Note: If the scanner does not oper-  
ate properly when you use a ciga-  
rette-lighter power cable, unplug the  
power cable from the cigarette-  
lighter socket and clean the socket to  
remove ashes and other debris.  
• The DC cigarette-lighter power  
cable must be capable of deliv-  
ering 12 volts and 500 milli-  
amps, its center tip must be set  
to positive, and its barrel plug  
must correctly fit the scanner's  
DC 12V  
jack. The recommended  
CONNECTING THE  
ANTENNA  
power cable meets these speci-  
fications. Using a power cable  
that does not meet these specifi-  
cations could damage the scan-  
ner or the power cable.  
To attach the supplied telescoping  
antenna to your scanner, simply  
screw it into the hole on top of your  
scanner.  
• Always plug the power cable  
into the scanner before you plug  
it into your vehicle's cigarette-  
lighter socket. Always unplug  
the power cable from the vehi-  
cle's cigarette-lighter socket  
before you unplug it from the  
scanner.  
Follow these steps to use vehicle  
battery power.

Warning: Use extreme caution when  
installing or removing an outdoor an-  
tenna. 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,  
cable or guy wires can cause electro-  
cution and death! Call the power  
company to remove the antenna. Do  
not attempt to do so yourself.  
Connecting an Optional  
Antenna  
The supplied telescoping antenna re-  
ceives strong, local signals. Howev-  
er, to receive weaker, more distant  
signals in all bands, you can attach  
an optional antenna, such as an ex-  
ternal mobile antenna or outdoor  
base station antenna. Your local Ra-  
dioShack store sells a variety of an-  
tennas.  
Cautions:  
• Do not run the cable over sharp  
edges or moving parts.  
Note: If you connect an external an-  
tenna, remove the telescoping an-  
tenna from the top of the scanner.  
• Do not run the cable next to  
power cables or other antenna  
cables.  
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 your antenna’s cable  
does not have a BNC connector, use  
a BNC adapter available at your local  
RadioShack store.  
• Do not run the cable through  
areas that produce extreme  
heat.  
• Follow all cautions and warnings  
included with the antenna.  
Follow the installation instructions  
supplied with the antenna, route the  
antenna cable to the scanner, then  
connect it to the ANT jack on the back  
of the scanner.

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 could be  
illegal in some areas.  
Even though some earphones and  
headphones let you hear some out-  
side sounds when listening at normal  
volume levels, they still can present a  
traffic hazard.

UNDERSTANDING YOUR SCANNER  
Once you understand a few simple terms we use in this manual and familiarize  
yourself with your scanner’s features, you can put the scanner to work for you.  
You simply find the communications you want to receive, then set the scanner  
to scan those frequencies.  
A frequency is the tuning location of a station (expressed in kHz or MHz). To  
find active frequencies, you can use the limit search function which lets you  
search within a specific range of frequencies or the direct search function  
which lets you search up or down from the currently displayed frequency.  
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.

Monitor Memories  
UNDERSTANDING THE  
SCANNER’S MEMORY  
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”  
on Page 20.  
You can store up to 210 frequencies  
into your scanner’s memory. This  
scanner has 200 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 20 channels  
each. Use each storage bank to  
group frequencies, such as the po-  
lice department, fire department, am-  
bulance services, or aircraft (see  
“Guide to the Action Bands” on  
Page 31).  
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 21 (the  
first channel in Bank 2).

Search Skip Memory  
You can skip specified frequencies  
during a limit, direct, or weather  
search (see “Listening to the Weath-  
er Band” on Page 25). This lets you  
avoid unwanted frequencies or ones  
you have already stored in a channel.  
You can program up to 20 frequen-  
cies to skip into the scanner’s memo-  
ry.  
To clear all the skip frequencies at  
once, while in the search mode, hold  
down L/O/SEARCH SKIP until the  
scanner beeps 2 times.

If necessary, readjust SQUELCH so  
you do not hear the hissing sound  
between transmissions.  
You can continuously monitor a spe-  
cific channel without scanning. This  
is useful if you hear an emergency  
broadcast on a channel and want to  
hear all the details (even though  
there might be periods of silence) or  
if you want to monitor only a specific  
channel or a locked-out channel.

SPECIAL FEATURES  
Note: If the scanner cannot find a pri-  
ority channel, P CH LOCOUt ap-  
pears when you turn on the priority  
feature.  
USING PRIORITY  
CHANNELS  
The priority feature lets you scan  
through channels and still not miss  
important or interesting calls on spe-  
cific channels. You can program one  
stored channel in each bank as a pri-  
ority channel (up to 10 stored chan-  
nels in total). As the scanner scans  
the bank, if the priority feature is  
turned on, the scanner checks the  
priority channels every 2 seconds for  
activity.  
To confirm all priority channel num-  
bers, press PGM, then repeatedly  
press PRI/HYPER SEARCH to see the  
priority channels.  
To turn on the priority feature, press  
PRI/HYPER SEARCH during scan-  
ning. PRIORITYappears and every  
2 seconds the scanner checks the  
priority channel in each bank that is  
turned on, starting from the lowest-  
numbered to the highest-numbered  
priority channel. If there is a trans-  
mission on the priority channel, the  
scanner tunes the transmission until  
it stops.  
The scanner automatically desig-  
nates each bank’s first channel as its  
priority channel. Follow these steps  
to select a different channel as the  
priority channel for a bank.  
1. Press PGM.  
The scanner does not check the  
channel if it is in a bank which is  
turned off or if the priority channel is  
locked out.

or frequencies. Then, when the scan-  
ner stops on the channel or frequen-  
cy, DELAYappears and the scanner  
continues to monitor the channel/fre-  
quency for 2 seconds after the trans-  
mission stops before it resumes  
scanning or searching.

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.  
GUIDE TO FREQUENCIES  
US Weather Frequencies  
162.400  
162.425  
162.450  
162.475  
162.500  
162.525  
162.550  
Canadian Weather Frequencies  
161.650  
161.775  
163.275  
Note: These frequencies are not pre-programmed in the weather service bank  
but can be manually programmed into a channel.  
Ham Radio Frequencies  
Ham radio operators often transmit emergency information when other means of  
communication break down. The following chart shows the frequencies the scan-  
ner receives that Ham radio operators normally use:  
Wavelength (meters)  
10–Meter  
6–Meter  
Frequencies (MHz)  
29.000–29.700  
50.000–54.000  
2–Meter  
70–cm  
33–cm  
144.000–148.000  
420.000–450.000  
902.000–928.000  
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 hear only  
noise on that frequency. If the interference is not severe, you might be able to  
turn SQUELCH clockwise to cut out the birdie.  
30  
 
The birdie frequencies on this unit to watch for are:  
31.200 MHz  
116.0375 MHz  
132.1755 MHz  
145.600 MHz  
823.800 MHz  
36.0500 MHz  
120.1625 MHz  
140.1900 MHz  
163.2200 MHz  
940.900 MHz  
114.400 MHz  
128.1750 MHz  
145.195 MHz  
813.400 MHz  
To find the birdies in your scanner, begin by disconnecting the antenna and mov-  
ing 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 frequen-  
cy 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.

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 neces-  
sary conversions.  
1 MHz (million) = 1,000 kHz (thousand)  
To convert MHz to kHz, multiply the number of megahertz by 1,000:  
9.62 (MHz) x 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-2048 200-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  
might 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 improp-  
erly.  
Use and store the scanner only in normal temperature environ-  
ments. Temperature extremes can shorten the life of electronic de-  
vices and distort or melt plastic parts.  
Keep the scanner away from dust and dirt, which can cause prema-  
ture 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 de-  
tergents to clean the scanner.  
Modifying or tampering with the scanner’s internal components can cause a mal-  
function and might invalidate your scanner’s warranty and void your FCC autho-  
rization to operate it. If your scanner is not performing as it should, take it to your  
local RadioShack store for assistance.
