INTRODUCTION
Your new RadioShack PRO-2052
1000-Channel Dual Trunking Trunk-
Tracker Home Scanner is one of a
new generation of scanners designed
to track MotorolaType I, Type II
(such as Smartnetand Privacy
Plus), GE/Ericsson EDACS, and hy-
brid analog trunking systems, which
are extensively used in many 800
MHz, 900 MHz and UHF communica-
tion systems.
Trunking communications systems let
a large group of 2-way radio users (or
even different groups of 2-way radio
users) efficiently use a group of fre-
quencies. Instead of selecting a spe-
cific frequency for a transmission, the
2-way radio user simply selects a talk
group. The trunking system automati-
cally transmits the call on the first
available frequency, and also sends a
code that uniquely identifies that 2-
way radio user’s transmission on a dif-
ferent frequency called a data chan-
nel.
Since the trunking system might send
individual 2-way radio user’s calls and
response transmissions on different
frequencies, it is difficult to listen to
trunked communications using a regu-
lar scanner. The PRO-2052 monitors
the data channel frequency sent with
a 2-way radio user’s transmission and
instantly switches to an active fre-
quency, so you can hear the call and
response for that 2-way radio user
and easily “follow” the conversation.
The scanner also lets you scan con-
ventional transmissions, and is pre-
programmed with service-search
banks for convenience. By pressing a
single button, you can quickly search
those frequencies most commonly
used by public service and other
agencies without tedious and compli-
cated programming.
This scanner gives you direct access
to over 51,000 exciting frequencies,
including those used by police and fire
departments, ambulance services,
and amateur radio services, and you
can change your selection at any time.
FEATURES
Your scanner also has these special
features:
Flexible Operation — you can track
both Motorola and GE/Ericsson trunk-
ing systems (used by most trunking
communications systems today), let-
ting you hear more calls than many
standard trunking scanners.
Frequency Coverage to 1.3 GHz —
provides a wide range of frequencies
you can listen to.
Twenty Channel-Storage Banks —
let you store 50 channels in each bank
(1000 total channels), letting you
group channels so you can more easi-
ly identify calls.

NWR-SAME/Weather Alert — you
can set the scanner to sound an alert
when it receives NOAA’s Specific
Area Message Encoding (SAME) cod-
ed weather emergency signal, provid-
ing more complete information about
weather conditions in your immediate
area and letting you avoid hearing
alerts for geographical areas that do
not interest you.
Remote PC Function — lets you con-
trol the PRO-2052 from your personal
computer.
Five Scan Lists — let you store up to
50 IDs in each tracking bank (up to a
total of 1000).
Triple-Conversion Circuitry — virtu-
ally eliminates any interference from
IF (intermediate frequency) images,
so you hear only the selected frequen-
cy.
Scan Delay — delays scanning for
about 2 seconds before moving to an-
other channel in conventional mode,
so you can hear more replies that are
made on the same channel. In trunk
scanning mode, it delays for about 5
seconds before moving to another ID.
Lock-Out Function — lets you set
your scanner to skip over specified
channels or frequencies when scan-
ning or searching, and skip over IDs
when tracking trunked systems.
Priority Channels — lets you pro-
gram one channel in each bank (10 in
all). As the scanner scans a bank, it
checks the bank’s priority channel ev-
ery 2 seconds so you don't miss trans-
missions on that channel.
Five Service-Search Banks — let
you search preset frequencies in sep-
arate public service, police, fire/emer-
gency, aircraft, and weather banks, to
make it easy to locate specific types of
calls.
HyperSearch and HyperScan —
let you set the scanner to search at up
to 300 steps per second (in frequency
bands with 5 kHz steps) and scan at
up to 50 channels per second, to help
you quickly find interesting broad-
casts. (The normal search speed is
100 steps per second).
Data Signal Skip — lets you set the
scanner to skip non-modulated or data
signals during scanning and searches.
This lets the scanner avoid non-voice
signals, making a scan or search fast-
er.
Manual Access — you can directly
access any stored channel by entering
that channel’s number.
Liquid-Crystal Display — makes it
easy to view and change program-
ming information.
Display Backlight — makes the
scanner easy to read in low-light situa-
tions.

Supplied Telescoping Antenna —
provides good reception of strong lo-
cal signals.
External Antenna Terminal — lets
you connect an external antenna with
a BNC connector to the scanner for
improved reception of distant/weaker
signals.
Memory Backup — keeps the chan-
nel frequencies stored in memory in
the event AC power goes out.
Key Confirmation Tones — the
scanner sounds a tone when you per-
form an operation correctly, and an er-
ror tone if you make an error.
Duplicate Channel Alert — warns
you when the frequency you are stor-
ing already exists in memory.
Disconnect Tone Detect — the scan-
ner automatically tunes to the trunking
data channel when it receives a dis-
connect transmission. You can turn
this feature off to continuously monitor
a channel with a weak transmission
during disconnected conversations.
Your PRO-2052 scanner can receive
these bands:

FCC NOTICE
Your scanner might cause radio or TV
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 the following methods
to eliminate the interference:
• Move your scanner away from the
receiver.
• Connect your scanner to an outlet
that is on a different electrical cir-
cuit from the receiver.
• Contact your local RadioShack
store for help.
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, 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:
• telephone conversations (cellular,
cordless, or other private means
of telephone signal transmission)
• 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).
This scanner is designed to prevent
reception of illegal transmissions, in
compliance with the law which re-
quires that scanners be manufactured
in such a way as to not be easily mod-
ifiable to pick up those transmissions.
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.
We encourage responsible, legal
scanner use.

PREPARATION
This scanner is designed primarily for
use in the home as a base station.
You can place it on a desk, shelf, or
table.
Your scanner’s front feet fold up or
down. Adjust them to give you the
best view of the display.
Your scanner’s display is protected
during shipment by a piece of film.
Peel off this film before you use the
scanner.
CONNECTING AN
ANTENNA
Connecting the Supplied
Antenna
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.
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 Outdoor
Antenna
Instead of the supplied antenna, you
can connect an outdoor base-station
or mobile antenna (not supplied) to
your scanner using a BNC connector.
Your local RadioShack store sells a
variety of antennas. Choose the one
that best meets your needs.
When deciding on a mobile or base-
station antenna and its location, con-
sider these points:
Frequency Antenna Length
29–54 MHz Extend fully
108–400 MHz Collapse one
segment
406–1300 MHz Collapse both
segments
20-432.fm Page 8 Friday, July 14, 2000 11:30 AM

• The antenna should be as high as
possible on the vehicle or build-
ing.
• 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.
To connect an optional base-station or
mobile antenna, first remove the sup-
plied antenna from the scanner. Al-
ways use 50-ohm coaxial cable, such
as RG-58 or RG-8, to connect the
base-station or mobile antenna. For
lengths over 50 feet, use RG-8 low-
loss dielectric coaxial cable. If the an-
tenna cable’s connector does not fit in
the ANT. jack, you might also need a
Motorola-to-BNC antenna plug adapt-
er, such as RadioShack Cat. No. 278-
117. Your local RadioShack store car-
ries a wide variety of coaxial antenna
cable and connectors.
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.
Cautions:
• 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.
Warning: Use extreme caution
when you install or remove an out-
door antenna. If the antenna starts to
fall, let it go! It could contact over-
head power lines. If the antenna
touches a power line, contact with
the antenna, mast, cable, or guy
wires can cause electrocution and
death. Call the power company to re-
move the antenna. DO NOT attempt
to do so yourself.
CONNECTING POWER
Using AC 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 DC 12V jack on the
back of the scanner, then plug the AC
adapter into a standard AC outlet.
ANT
20-432.fm Page 9 Friday, July 14, 2000 11:30 AM

10
Cautions:
You must use a Class 2
power source that sup-
plies 12V DC and deliv-
ers at least 500 mA. Its center tip
must be set to positive and its
plug must fit the scanner's DC 12V
jack. The supplied adapter meets
these specifications. Using an
adapter that does not meet these
specifications could damage the
scanner or the adapter.
• Always connect the AC adapter to
the scanner before you connect it
to AC power. When you finish, dis-
connect the adapter from AC
power before you disconnect it
from 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.
Using Your Vehicle’s Battery
Power
If your AC power fails (during an
emergency, for example), you can
power your scanner from your vehi-
cle’s cigarette lighter socket with an
optional DC cigarette lighter power ca-
ble, (not supplied).
To connect an optional DC cigarette
lighter power cable, insert its barrel
plug into the DC 12V jack on the back
of the scanner, then plug the power
cable into your vehicle’s cigarette
lighter socket.
Cautions:
You must use a power
source that supplies 12V
DC and delivers at least
500 mA. Its center tip must be set
to positive and its plug must fit the
scanner's DC 12V jack. The sup-
plied adapter meets these specifi-
cations. Using an adapter that
does not meet these specifica-
tions could damage the scanner
or the adapter.
• Always connect the adapter to the
scanner before you connect it to
the power source. When you fin-
ish, disconnect the DC adapter
from the power source before you
disconnect it from the scanner.
Note: If you use a cigarette lighter
power cable and your vehicle’s engine
is running, you might hear electrical
noise from the engine while scanning.
This is normal.
CONNECTING AN
EXTENSION SPEAKER
In a noisy area, an amplified extension
speaker (available at your local Ra-
dioShack store) positioned in the right
place, might provide more comfortable
listening.

Plug the speaker cable’s 1/8-inch (3.5-
mm) plug into your scanner’s jack.
Note: Connecting an external speaker
disconnects the scanner’s internal
speaker.
CONNECTING AN
EARPHONE/
HEADPHONES
For private listening, you can connect
an earphone or headphones with a 1/8-
inch (3.5-mm) plug to the jack on
the front of the scanner. (Your local
RadioShack store carries a wide se-
lection of earphones and head-
phones). This automatically dis-
connects 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. Extended high-
volume listening can lead to per-
manent hearing loss.
•Set
VOLUME to the lowest setting
before you begin listening. After
you begin listening, adjust VOL-
UME to a comfortable level.
• Once you set 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 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 determine the type of communications you want to receive, then set the
scanner to scan them.
A frequency is the tuning location of a station (expressed in kHz or MHz). To find
active frequencies, you can use the search function.
You can also search the service-search banks, which are preset groups of fre-
quencies categorized by type of service.
When you find a frequency, you can store it into a programmable 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.
A LOOK AT THE FRONT PANEL
Your scanner’s keys might seem confusing at first, but this information should help
you understand each key’s function.
Note: Some of the scanner’s keys perform more than one function and are marked
with more than one label. The steps in this Owner’s Manual show only the label on
the key appropriate to the action being performed.
VOLUME Turns the scanner on or off and adjusts the volume.
SQUELCH Adjusts the scanner’s squelch.

UNDERSTANDING
BANKS
Channel Storage Banks
To make it easier to identify and select
the channels you want to listen to,
channels are divided into 20 banks of
50 channels each. Use each channel-
storage bank to group frequencies,
such as those used by the police de-
partment, fire department, ambulance
services, or aircraft (see “Guide to the
Action Bands” on Page 56).
For example, the police department
might use four frequencies, one for
each side of town. You could program
the police frequencies starting with
Channel 1 (the first channel in bank 1)
and program the fire department fre-
quencies starting with Channel 51 (the
first channel in bank 2).
Service Banks
The scanner is preprogrammed with
the frequencies allocated by public
safety, police, fire/emergency, aircraft,
and weather services. This is handy
for quickly finding active frequencies
instead of searching through an entire
band (see “Searching Service Banks”
on Page 19).
UNDERSTANDING
TRUNKING
In the past, groups that broadcast fre-
quently, such as police departments,
were restricted to transmitting on just
a few frequencies. This resulted in
heavy traffic and often required 2-way
radio users to wait for a specific fre-
quency to clear before transmitting.
Trunked systems allow more groups
of 2-way radio users to use fewer fre-
quencies. Instead of selecting a spe-
cific frequency to transmit on, a
trunked system chooses one of sever-
al frequencies when the 2-way radio
user presses PTT (push to talk). The
system automatically transmits the
call on that frequency, and also sends
a code that identifies that 2-way radio
user’s transmission on a data channel.
You can set this scanner to monitor
the data channel frequency, so you
can hear both the call and response
transmissions for that 2-way radio
user and therefore follow the conver-
sation. (You cannot listen to the data
channel itself in trunking mode.)

OPERATION
TURNING ON THE
SCANNER AND SETTING
SQUELCH
1. Turn SQUELCH and VOLUME fully
counterclockwise.
2. Turn VOLUME back clockwise until
you hear a hissing sound.
3. Turn SQUELCH clockwise, then
leave it set to a point just after the
hissing sound stops.
Notes:
• If the scanner does not scan, turn
SQUELCH further clockwise.
• If the scanner picks up unwanted,
partial, or very weak transmis-
sions, turn SQUELCH clockwise to
decrease the scanner’s sensitivity
to these signals. If you want to lis-
ten to a weak or distant station,
turn SQUELCH counterclockwise.
• If SQUELCH is adjusted so you
always hear a hissing sound, the
scanner will not scan properly.
STORING KNOWN
FREQUENCIES INTO
CHANNELS
Good references for active frequen-
cies are the RadioShack “Police Call
Guide including Fire and Emergency
Services,” “Official Aeronautical Fre-
quency Directory,” and “Maritime Fre-
quency Directory.” We update these
directories every year, so be sure to
get a current copy.
Note: To store trunking system fre-
quencies, see “Programming Trunked
Frequencies” on Page 32.
Follow these steps to store frequen-
cies into channels.
1. Press MANUAL, enter the chan-
nel number (1–1000) where you
want to store a frequency, then
press MANUAL again. The chan-
nel number appears.
2. Use the number keys and •to
enter the frequency (including the
decimal point) you want to store.
3. Press Eto store the frequency into
the channel.
Notes:
• If you made a mistake in Step
2, Error appears and the
scanner beeps when you press
E. Simply start again from Step
2.
• Your scanner automatically
