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.

HyperSearch and HyperScan are trademarks used by Tandy Corporation.

20-432.fm Page 2 Friday, July 14, 2000 11:30 AM

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.

20-432.fm Page 3 Friday, July 14, 2000 11:30 AM

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

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.

D C 12V

ANT

20-432.fm Page 10 Friday, July 14, 2000 11:30 AM

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.

20-432.fm Page 11 Friday, July 14, 2000 11:30 AM

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.)

20-432.fm Page 17 Friday, July 14, 2000 11:30 AM

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 E to store the frequency into

the channel.

Notes:

• If you made a mistake in Step

SEARCHING SERVICE

BANKS

You can search for public service, po-

lice, fire/emergency, aircraft, and

weather transmissions even if you do

not know the specific frequencies that

are used in your area. You can also

store any of the frequencies you find

into channels.

Your scanner has the following pre-

programmed service banks.

• PUB — contains 140 public ser-

vice frequencies

• POLICE — contains 2,392 police

frequencies

• FIRE/EMG — contains 197 fire

and emergency service frequen-

cies

• AIR — contains 2,319 aircraft and

air service frequencies

• WX — contains 7 weather fre-

quencies

To select a service bank, press SVC.

(activity indicator) appears above

the service bank’s name (PUB, PO-

LICE, FIRE/EMG, AIR, and WX),

and one of the preset public service

frequencies appear. After a 2-second

delay, scanning begins in the selected

bank.

To select another service bank, re-

peatedly press SVC until appears

above the name of the bank you want

to use.

Notes:

• To skip data signals (such as

modem signals), press DATA. See

“Skipping Data Signals” on

Page 25.

• Because frequencies are not

always assigned to the same ser-

vices everywhere, you might hear

transmissions from one service in

another service bank.

through channels and still not miss im-

portant or interesting calls on specific

channels. You can program one

stored channel in each bank as a pri-

20-432.fm Page 21 Friday, July 14, 2000 11:30 AM

ority channel (for up to a total of 10

stored channels). As the scanner

scans the bank, if the priority feature is

turned on, the scanner checks the pri-

ority channel for activity every 2 sec-

onds.

SPECIAL FEATURES

DELAY

Many agencies use a two-way radio

system that might have a period of 2

or more seconds between a transmis-

sion and a reply. To keep from miss-

ing a reply, you can program a 2-

second delay into any channel or fre-

quency. The scanner continues to

monitor the frequency for 2 seconds

after the transmission stops before re-

suming scanning or searching.

To program a 2-second delay:

• If the scanner is scanning chan-

nel-storage banks and stops on

an active channel where you want

to store a delay, quickly press

DELAY before scanning resumes.

DELAY appears.

• If the desired channel is not

selected, manually select the

channel, then press DELAY.

DELAY appears.

• If the scanner is searching, press

DELAY. DELAY appears and the

scanner automatically adds a 2-

second delay to every transmis-

sion it stops on in that band or

limit range.

To turn off the 2-second delay, press

DELAY while the scanner is monitoring

the channel or searching service

banks or limit ranges. DELAY disap-

pears.

TURNING CHANNEL-

STORAGE BANKS ON

AND OFF

You can turn each channel-storage

bank on and off. When you turn off a

bank, the scanner does not scan any

of the 50 channels in that bank.

For banks 1–10, while scanning press

the number key that corresponds to

the bank you want to turn on or off.

For banks 11–20, press SHIFT, then

press the number key that corre-

sponds to the bank you want to turn

on or off.

Notes:

• You can manually select any

channel within a bank, even if that

bank is turned off.

• You cannot turn off all banks. One

bank is always active.

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.

Note: If you just want to skip over a

lengthy transmission (such as a mo-

dem signal), see “Skipping Data Sig-

nals” on Page 25.

speeds for a limit search.

To switch between the normal and Hy-

perSearch speeds during a limit

search, press SPEED. SEARCH flash-

es during HyperSearch.

Note: You can use HyperSearch only

in the 5 kHz step bands (29–54 MHz,

137–174 MHz, and 216–224.995

MHz).

SKIPPING DATA

SIGNALS

You can set the scanner so it skips

nonmodulated or data signals (such

as modem transmissions) during a

scan or search.

Note: Since data signals are not gen-

erally found in the air and VHF TV

bands, this feature does not work in

those bands.

To turn on the data skip feature, be

sure the priority feature is turned off

(see “Priority” on Page 21), then press

DATA. DATA appears. To turn off the

feature, press DATA again. DATA dis-

appears.

USING NWR-SAME AND

WEATHER ALERT

Traditional weather radios simply re-

ceive the NOAA (National Oceanic

and Atmospheric Administration) wea-

ther broadcast (usually within a 50-

mile radius), then sound an alarm if

any emergency code was transmitted

along with the broadcast. This means

that people who live outside an affect-

ed area are often alerted even when

their area is not affected, causing

many of them to ignore potentially real

weather warnings that can save lives.

In 1994, NOAA began broadcasting

coded signals called FIPS (Federal In-

formation Processing System) codes

along with their standard weather

broadcasts from stations in your area.

These codes identify the type of emer-

gency and the specific geographic

area (such as a county) affected by

the emergency. Your scanner re-

ceives, interprets, and displays infor-

mation about the codes so you can

determine if the emergency might

affect your area. Only SAME-

compatible radios (such as this

scanner) are able to take advantage

of this new technology.

Normal Search HyperSearch

100 steps/

second 300 steps/

second

20-432.fm Page 25 Friday, July 14, 2000 11:30 AM

Each FIPS code identifies a specific

geographic area (defined by the Na-

tional Weather Service), so your scan-

ner sounds an alert only when a

weather emergency is declared in that

area. This helps you more efficiently

track the weather conditions in and

around your area.

When a Weather Alert Occurs

When the scanner receives a weather

alert:

• it sounds a series of beeps

• an indicator appears

The scanner also receives other

weather-related signals such as test

events (TSt appears) and other

events (--- appears)

Warning: The NWS (National Weath-

er Service) uses sophisticated weath-

er models to determine an alert’s

effective time. However, the end of an

alert does not necessarily mean that

the related weather emergency is

over.

Note: Once the scanner receives the

SAME code, it retains the information

in the scanner’s memory. This infor-

mation stays in memory even if you

change modes, but is erased when

you turn the scanner off.

Understanding FIPS Codes

For the purpose of broadcasting

weather information, the NWS has di-

vided the United States into regions

by state and county (or parish, where

applicable) then assigned a 6-digit

FIPS code to identify each county or

parish. For example, the code for Tar-

rant County, Texas, is 048439.

The first

digit in a

FIPS code

identifies

the county

subdivi-

sion, the

next two

digits identify the state, and the last

three digits identify the county or par-

ish.

Note: Most FIPS codes begin with 0,

which means the code represents an

entire county. The NWS, however,

plans to eventually subdivide some

large counties. When that happens,

each subdivision will be assigned a

digit from 1–9, resulting in codes such

as 148439, 248439, and so on.

Your scanner can receive all SAME

alert signals broadcast within about a

50-mile radius of where you installed

it. To receive SAME alerts and broad-

casts about weather occurring only in

particular counties within that area,

you can program up to fifteen FIPS

codes into the scanner’s memory (see

“Entering Your Area’s FIPS Code(s)”

048439

State

County Subdivision

County/

Parish

20-432.fm Page 26 Friday, July 14, 2000 11:30 AM

on Page 28). For example, this lets

you avoid hearing an alert that applies

to an area within a 50-mile radius but

not necessarily to your county or par-

ish.

Note: If you do not program any FIPS

location codes into the scanner’s first

memory (F1), the scanner sounds an

alert if it receives a weather alert with

any FIPS code.

Obtaining Your Area’s

FIPS Code(s)

To obtain the FIPS code for the loca-

tion where you installed your scanner,

contact your local RadioShack store

or call the NWS toll free at 1-888-

NWR-SAME (1-888-697-7263). If you

call the NWS, follow the instructions

you hear.

Note: If you are close to a county or

parish line, you might want to obtain

the codes for the nearby counties or

parishes.

Hint: Since you can program up to fif-

teen FIPS codes into the scanner’s

memory, you might want to obtain the

code for other local areas that you fre-

quently travel through (as long as

these areas are within a 50 mile radius

of your location and within an area

covered by your local NWS broadcast

station). That way, you can program

those codes into the scanner and re-

ceive broadcasts covering those loca-

tions, too.

Turning on the SAME and

Weather Alert

1. Repeatedly press SVC until

appears above WX.

2. Press ALERT. ALERT appears

and the scanner is set to receive a

SAME-coded signal. The scan-

ner’s audio is muted until it

receives the signal.

When the scanner receives a SAME-

coded signal, it sounds a series of

beeps,

ALERT flashes, and L3 (if the

broadcast is a statement), L2 (if the

broadcast is a watch), or L1 (if the

broadcast is a warning) appears. After

that, the scanner automatically tunes

to the weather channel where the

code was broadcast and you hear the

weather broadcast.

To stop the alert, press any key on the

scanner. The alert sound stops and

you hear the weather broadcast.

Warning: If severe weather threatens,

do not wait for an alert tone; turn on

the weather broadcast and monitor

the weather information.

To detect a SAME-coded signal on a

specific weather channel, press HOLD

during weather search to stop on a

specific channel, press ▲ or ▼ to se-

lect the desired weather channel, then

press ALERT. ALERT appears.

When the scanner detects a SAME-

coded signal broadcast on the weath-

er channel you selected, it sounds a

20-432.fm Page 27 Friday, July 14, 2000 11:30 AM

series of beeps and L3 (if the broad-

cast is a statement), L2 (if the broad-

cast is a watch), or L1 (if the

broadcast is a warning) appears.

Once the scanner receives a SAME-

coded signal, it retains the information

in its memory. This information stays

in memory even if you change modes,

but is erased when you turn off the

scanner. You can switch to weather

search mode to check the alert level.

Entering Your Area’s FIPS

Code(s)

1. Turn on the SAME alert function

(see “Turning on the SAME and

Weather Alert” on Page 27).

2. Hold down E until F1 appears.

3. Enter the FIPS code using the

number keys, then press E.

4. To enter another FIPS code, press

▲ or ▼, then repeat Steps 2 and

Note: To clear a FIPS code you

entered in Step 3 (while the code

appears on the display), press 0

then E.

5. When you finish, press SVC.

Note: If you do not program any FIPS

location codes into the scanner’s first

memory (F1), the scanner sounds an

alert if it receives a weather alert with

any FIPS code.

TESTING WEATHER

ALERT RECEPTION

For your scanner to effectively warn

you about weather alert signals, you

must place it where it can receive an

emergency alert broadcast and where

you can hear its alert tone.

In the United States, the NWS broad-

casts a test alert every week on

Wednesday between 11 AM and 1

PM. To find out the specific test

schedule in your area, contact your lo-

cal NOAA or NWS office. These offic-

es are usually listed in the telephone

book under “US Government, Depart-

ment of Commerce.”

Important: The fact that you get clear

reception of a weather broadcast sig-

nal does

not

guarantee that an emer-

gency alert broadcast will trigger your

scanner’s alert function.

Note: The NWS might not broadcast

the test alert if there is bad weather in

any surrounding area.

Testing the Alert Beep

1. If necessary, repeatedly press

SVC until appears above WX.

2. If necessary, press ALERT so

ALERT is not on the display.

3. Hold down ALERT for about 3 sec-

onds. The scanner sounds a loud

series of beeps.

4. Press any key to stop the alert.

20-432.fm Page 28 Friday, July 14, 2000 11:30 AM

Testing NWR-SAME Code

Detection

1. Turn on the SAME alert function

(see “Turning on the SAME and

Weather Alert” on Page 27).

2. Hold down ALERT for about 3 sec-

onds. The selected frequency

number and TESt alternate on

the display. Then, when the scan-

ner receives a test code, TSt

appears.

3. Press ALERT to exit the test

mode.

TRUNK SCANNING

Your scanner is designed to track

transmissions on Motorola Type I,

Type II, GE/Ericsson EDACS, and hy-

brid analog trunking systems. Re-

member these important points when

tracking transmissions:

• Your scanner monitors Type II

systems by default. However, you

can change this if the system in

your area is different (see “Types

of Trunking Systems” on this page

and “Scanning Type I and Hybrid

Trunked Systems” on Page 40 for

more information).

• Your scanner tracks a trunked

system

scans frequencies in

conventional mode, but it cannot

do both at the same time.

• The frequencies for many of the

800 MHz public safety systems

are listed in the separate “National

Public Safety Trunked System

Frequency & Talk Group Guide”

included with this scanner.

TYPES OF TRUNKING

SYSTEMS

Your trunk scanning scanner can

monitor three basic types of systems

—

Type I

Type II, and EDACS

. In-

stead of selecting a specific frequency

to transmit on, a trunked system

chooses one of several frequencies in

a 2-way radio user’s talk group when

that user presses PTT (push to talk).

Thus, trunking systems allocate a few

frequencies among many different us-

ers, but the way Type I and Type II

systems do this is slightly different.

One important distinction between

these systems is the amount of data

transmitted by each radio when its

PTT button is pressed. In a Type I

system, the radio’s talk group ID and

its current affiliation (the trunk system

it belongs to) are both transmitted. In a

Type II system, only the radio’s talk

group ID is transmitted.

Why the difference? In Type I sys-

tems, each radio in the trunk group in-

dividually transmits its own affiliation,

while the trunk system maintains a da-

tabase that determines each radio's

affiliation(s) in Type II systems.

Another difference between the sys-

tems is that Type I systems are ar-

ranged in a fleet-subfleet hierarchy.

For example, it is possible for a city

using a Type I system to designate

four fleets, each with eight subfleets.

20-432.fm Page 30 Friday, July 14, 2000 11:30 AM

The fleets might be the police depart-

ment, the fire department, the utilities,

and city administration. The police

might decide to further divide its fleet

into subfleets such as dispatch, tacti-

cal operations, detectives, north,

south, east, and west side patrols, and

supervisors. All the available police ra-

dios would then be assigned to one of

the police subfleets, letting the police

centralize their communications and

control the type of users on a single

system. Determining the exact fleet-

subfleet hierarchy for a particular area

is referred to as

fleet map program-

ming

The disadvantage of a Type I system

is that the brief burst of data sent

when a user transmits must contain

the radio’s talk group ID, and its fleet

and subfleet. This is three times the

amount of data a Type II system radio

sends. Since the data capacity of

Type I systems is limited and the

amount of data increases with each

user, Type I systems usually accom-

modate fewer users than Type II sys-

tems. Nevertheless, Type I systems

are still in use.

There are also

hybrid

systems which

are a combination of both Type I and

Type II. Your scanner defaults to mon-

itor Type II systems, but you can

change to Type I or a hybrid of Type I

and Type II systems by selecting a pre

programmed fleet map or creating a

custom fleet map for your area (see

“Scanning Type I and Hybrid Trunked

Systems” on Page 40).

You do not need to determine the

fleet-subfleet hierarchy for Type II sys-

tems unless you are tracking hybrid

systems that contain both Type I and

Type II systems.

SETTING THE SCANNER

TO THE TRUNK

SCANNING MODE

Press TRUNK to switch between the

scanner’s conventional and trunk

scanning modes.

SETTING SQUELCH FOR

THE TRUNK SCANNING

MODE

The squelch setting can affect how

fast your scanner acquires the data

channel, and in some instances, can

prevent your scanner from acquiring

the data channel at all.

Adjusting SQUELCH is necessary to

track transmissions precisely.

20-432.fm Page 31 Friday, July 14, 2000 11:30 AM

We recommend you set SQUELCH to

the position shown here before select-

ing a trunked bank.

Note: Change this setting as neces-

sary to get the best performance in

your area.

PROGRAMMING

TRUNKED

FREQUENCIES

Before you program your scanner to

track a trunked system, consider the

following:

• Valid trunked system frequencies

are as shown below.

Motorola system

935.0125–939.9875 MHz

(in 12.5 kHz steps)

851.0000–868.9875 MHz

(in 12.5 kHz steps)

406.0000–512.0000 MHz

(in 12.5 kHz steps)

137.0000–174.0000 MHz

(in 5 kHz steps)

Ericsson EDACS system

900.0000–956.000 MHz

(in 12.5 kHz steps)

806.0000–899.9875 MHz

(in 12.5 kHz steps, except

cellular frequencies)

406.0000–512.0000 MHz

(in 12.5 kHz steps)

137.0000–174.0000 MHz

(in 5 kHz steps)

• You can use any of your scanner’s

banks as either a trunk scanning

bank or conventional scanning

bank, but you cannot mix the two.

• The scanner only scans one

trunked system at a time. Al-

though you can store frequencies

for more than one trunked system

in one of your scanner’s banks,

the scanner only scans the fre-

quencies associated with the first

data channel it finds.

Before scanning a trunked system’s

transmissions, you must store the

trunked system’s frequencies in one of

the banks in your scanner by following

these steps.

1. Set the scanner for conventional

scanning, then hold down TRUNK

until the scanner beeps twice.

BANK, TRUNK, and the bank

numbers flash.

2. Press a number key to select the

bank for the trunked system’s fre-

quencies. To select a bank

between 11 and 20, press SHIFT

then the number keys. The scan-

ner displays one of six system

types.

3. Use

▲ or ▼ to select the system

type, then press E.

20-432.fm Page 32 Friday, July 14, 2000 11:30 AM

4. Use the number keys to enter the

trunked system’s frequencies,

then press E.

Note: If you entered an invalid fre-

quency, the scanner beeps, the

channel number flashes and

Error appears. Press CLEAR to

clear the frequency, then repeat

Step 4.

5. Press either MANUAL or ▲ to

select the next channel in the

bank.

6. Repeat Steps 4 and 5 until all fre-

quencies have been entered.

SCANNING A TRUNKED

BANK

You can scan one trunked bank at a

time. Once you have stored frequen-

cies for a trunked system in one or

more of the 20 available banks, and

you are scanning non-trunked fre-

quencies, follow these steps to begin

trunk scanning.

1. Turn on the scanner and begin

scanning in conventional mode.

2. Press TRUNK. The indicators for

all banks that have been pro-

grammed with trunked frequen-

cies flash, and TRUNK and BANK

appear.

3. To see all banks programmed with

Motorola system frequencies,

press

▲. All banks programmed

with Motorola system frequencies

flash. To see all banks pro-

grammed with EDACS system fre-

quencies, press ▲ again. All

banks programmed with EDACS

system frequencies flash.

4. Use the number keys to activate

the trunked bank you want to

scan. appears under the

selected bank’s number.

5. Press SEARCH. As the scanner

searches for the trunk’s data

channel (the channel that con-

trols the trunk), SEARCH flashes.

When the scanner finds the data

channel, it begins trunk scanning.

If you entered all of the trunk’s fre-

quencies, you should be able to

follow conversations between

broadcasters even when they

change frequencies. IDs which

represent different service groups

appear.

Note: To see the bank currently in

use (for about 5 seconds), press

DATA.

6. To return to conventional scan-

ning, press TRUNK again.

Hint: While scanning, you will not

know exactly whom the talkgroup IDs

are assigned to until you listen awhile

or until you locate talkgroup ID lists in

frequency guides or on internet sites

such as www.trunkscanner.com. With-

in a few minutes, you can usually fig-

ure out if what you are listening to is a

police, fire, or emergency medical 2-

way radio user. Other talkgroup IDs

might take some time, but determining

whom each ID represents is half the

fun of trunk scanning!

Turning Banks On or Off

During Trunk Scanning

As in conventional scanning, you can

turn each channel-storage bank on

and off during trunk scanning. When

you turn off a bank, the scanner does

not scan any of the 50 channels in that

bank.

1. Press DATA. All active trunk bank

numbers appear.

2. Press the number key for the bank

you want to add or delete.

If the bank number is off, the scanner

does not scan any of the channels

within that bank.

Skipping the Trunked Bank

To skip to another trunked bank while

you are listening to a trunked bank,

hold down DATA.

Turning Status Bit Ignore

On or Off

You can set how your scanner works

with

status bits

(also called S-bits), let-

ting you control how the scanner inter-

prets and displays talkgroup IDs.

The last four bits of a Motorola Type II

talkgroup ID (a binary 16-bit code) are

the status bits. In some systems, sta-

tus bits identify special situations

(such as an emergency status).

Your scanner is preset to assume that

the status bits in a talkgroup ID are set

to 0 and ignores them. For example,

when the scanner receives the talk-

group ID 010111001110 0011, it

reads the ID as 010111001110 0000

and converts the first 12 bits of the ID

to 23776 (the talkgroup ID). However,

since the status bit value is 3 (0011

converted to decimal equals 3), the ID

is actually 23779.

If you are scanning a Motorola Type I

system and do not have a fleet map

for that system, you might have to turn

off status bit ignore in order to deter-

mine the proper fleet map.

Important: If you are scanning any

system other than a Motorola Type I

system, be sure status bit ignore is set

to ON or you will miss some transmis-

sions.

20-432.fm Page 34 Friday, July 14, 2000 11:30 AM

Follow these steps to turn status bit ig-

nore on or off.

1. Hold down SCAN until the current

status bit ignore setting (ON or

OFF) appears.

2. Press ▲ or ▼ to select ON or OFF,

then press E.

Identifying a Trunked

Frequency

To identify a trunked frequency, press

▼ when the scanner stops on a talk-

group ID. The trunked frequency brief-

ly flashes twice. To show the fre-

quency longer, hold down ▼. The

scanner beeps, then the trunked fre-

quency and talkgroup ID alternate.

Switching EDACS Format

The EDACS system uses two group

ID formats: Agency-Fleet-Subfleet

(AFS) and Decimal. If you use a list of

IDs shown in one format (AFS) and

the ID you want to receive is in the

other format (such as decimal, for ex-

ample), hold down SVC to switch to

the decimal format. The ID appears in

decimal format and E flashes.

EDACS ID Range Search

To make searching for EDACS IDs

faster, set a range for the Agency or

Fleet listings. Simply use the number

keys to enter the Agency or the Agen-

cy and the Fleet listing, then press

SEARCH. Note the following exam-

ples.

Example 1

Agency = 01

Press 0 1 . SEARCH.

01 --- appears during search.

Example 2

Agency = 01, Fleet = 01

Press 0 1 . 0 1 SEARCH.

01-01- appears during search.

To stop an ID range search, press

SEARCH again.

Using Trunk Scanning Scan

Delay

Many trunked systems have a period

of 2 or more seconds between a trans-

mission and a reply. You can pro-

gram a 5-second delay so the

scanner holds on an ID for 5 seconds

to wait for a reply. The scanner contin-

ues to monitor the frequency for 5 sec-

onds after the transmission stops

before resuming scanning.

Press DELAY to turn trunk scanning

scan delay on or off. DELAY appears

when trunk scanning scan delay is

set.

20-432.fm Page 35 Friday, July 14, 2000 11:30 AM

Note: If you consistently miss re-

sponses even with trunk scanning

scan delay set, you might need to

change the default system type or the

fleet map you are using. See “Scan-

ning Type I and Hybrid Trunked Sys-

tems” on Page 40.

Monitoring an Active ID

When the scanner stops on a trans-

mission, follow these steps to hold the

scanner on that transmission.

Note: You can also follow these steps

to hold on an ID while scanning a scan

list. See “Scan Lists” on Page 37.

1. Press HOLD. HOLD appears and

the scanner stays on the current

ID.

2. To continue trunk scanning, press

SEARCH.

Locking Out IDs

As with conventional scanning, it is

possible to lock out unwanted traffic.

This is particularly important in trunk-

ed systems because signals you can-

not listen to (such as water meters,

door alarms, traffic signals, and en-

crypted signals) are assigned IDs just

like other users. You can lock out up

to 100 IDs.

To lock out an ID, press L/O when the

ID appears. The ID is locked out, and

the next active ID appears.

Note: If you lock out an ID while

searching, it is also locked out of the

scan list(s). See “Scan Lists” on

Page 37.

Unlocking a Single ID

1. Hold down L/O until you hear two

short beeps.

2. Repeatedly press ▼ or ▲ to select

the ID you want to unlock.

3. Press L/O. The ID is unlocked and

the next locked ID appears.

4. Press SEARCH to resume the pre-

viously selected function.

Unlocking All IDs

Hold down L/O until you hear two short

beeps, then press E to unlock all the

IDs at once. The scanner beeps twice.

Note: When you unlock all the IDs,

the scan list mode appears. Press

SCAN to scan the IDs stored in your

scan lists or press SEARCH to resume

the previously selected function. For

more information about scan lists, see

“Scan Lists” on Page 37.

20-432.fm Page 36 Friday, July 14, 2000 11:30 AM

MONITORING IDS

You can use your scanner’s display to

monitor the frequencies in a trunked

system for activity. You cannot hear

conversations in this mode, but this is

an excellent way to determine which

talk groups are the most active.

To set the scanner to monitor IDs,

hold down SEARCH until the scanner

beeps twice. SEARCH flashes, and all

talk group IDs appear in succession.

To stop monitoring IDs, press

SEARCH again.

Note: When you monitor IDs, locked-

out IDs also appear.

CHANNEL ACTIVITY

INDICATORS

Your scanner has 20 channel activity

indicators (bars). The bars show that

transmissions are being received on a

trunked system.

You can use the bars to tell how many

frequencies are being used and gen-

erally monitor how much communica-

tion traffic is occurring on a trunked

system.

• A bar that remains on steadily

even when there are no current

transmissions represents the fre-

quency being used as the data

channel.

• The bar that flashes when an ID

appears represents the frequency

being used by the radio you are

currently hearing.

• If a bar turns on but you do not

hear a conversation, the channel

is probably being used for a tele-

phone interconnect call or a pri-

vate call, or the indicator might be

a locked-out ID. Your scanner

does not monitor these types of

calls.

• If the scanner is holding on an ID

which is not active, the other bars

turn on and off as other groups

use the system

A bar appears for each frequency you

store in a trunking bank.

SCAN LISTS

When you program trunked frequen-

cies into a bank (see “Programming

Trunked Frequencies” on Page 32),

your scanner sets up 5 scan lists into

which you can store your favorite IDs.

Each list can contain up to 10 IDs, so

you can store a total of 50 IDs for each

trunk scanning bank (1000 IDs if you

use all banks as trunking banks).

20-432.fm Page 37 Friday, July 14, 2000 11:30 AM

Scan lists help you organize trunking

system users into categories. For ex-

ample, you might use List 1 for police

IDs, List 2 for fire department IDs, List

3 for emergency medical service IDs,

and so on. Once IDs are stored in

lists, you can scan them like you scan

conventional channels. You can pro-

gram IDs into scan lists manually, dur-

ing a search, or automatically.

Manually Storing IDs into

Scan Lists

1. Select the desired trunking bank

(see “Scanning a Trunked Bank”

on Page 33).

2. After the scanner begins trunk

scanning, press MANUAL. A scan

list number appears at the top of

the display, and a bar shows the

channel activity.

3. Repeatedly press ▲ or ▼ to select

the scan list location you want to

program.

4. Enter the Type II ID you want to

store, then press E.

Or, to enter a Type I ID:

a. Use the number keys to enter

the block number and the fleet

number, then press •.

b. Enter the subfleet number, then

press E.

Note: To clear a mistake while

entering an ID, press CLEAR, then

start over at Step 4.

Or, to enter an EDACS ID:

a. Use the number keys to enter

the agency number, then press •.

b. Enter the fleet number, then the

subfleet number, then press E.

5. Repeatedly press MANUAL or ▲

to select the next scan list location

you want to program. Then repeat

Step 4 to enter another ID.

Storing IDs into Scan Lists

SCANNING THE SCAN

LISTS

Press SCAN to begin scanning the

lists you have programmed. Id

SCAN scrolls on the display.

Note: If more than one of the scan IDs

you have stored do not work, Error

flashes twice and the scanner beeps

several times, then the scan list num-

bers appear at the top of the display.

To remove a scan list from active

scanning, use the number keys to en-

ter the scan list’s number. The scan

list indicator turns off, and the IDs in

that list are not scanned.

Note: You cannot remove all the scan

lists. One scan list must always be ac-

tive.

To restore a scan list to active scan-

ning, use the number keys to enter its

number again.

Press SEARCH to return to the previ-

ously selected function.

Priority ID Scanning

As in conventional scanning, you can

designate one ID in each scan list as a

priority ID.

To select an ID as a priority ID, hold

down PRIORITY for about 2 seconds

when the scanner stops on the ID. P

appears.

20-432.fm Page 39 Friday, July 14, 2000 11:30 AM

Press PRIORITY to turn on priority

scanning.

Note: Priority scanning does not work

if the ID is locked out.

SCANNING TYPE I AND

HYBRID TRUNKED

SYSTEMS

Your PRO-2052 is set to scan Type II

user IDs by default. When you scan

trunked frequencies, each Type II user

ID you see appears as an even num-

ber without a dash (such as 2160).

Your PRO-2052 can also scan Type I

trunked systems. Each Type I ID ap-

pears as a three- or four-digit number,

followed by a hyphen, followed by a

one- or two-digit number (such as

200-14).

If you notice a mix of odd- and even-

user IDs (such as 6477, 2160, 6481,

6144, and 1167), then you are proba-

bly monitoring either a Type I or hybrid

(a combination of Type I and Type II

user IDs) system. (See “Types of

Trunking Systems” on Page 30).

You might also notice that you are

missing responses when you hold on

an active ID. Unlike Type II systems,

Type I and hybrid systems require a

fleet map that sets specific fleet-

subfleet parameters. It is easy to se-

lect a fleet map to scan; what is not al-

ways easy is selecting or program-

ming a map that is being used in your

particular area.

When a Type I system is designed,

the address information for all its user

IDs is divided into 8 equal-size blocks,

numbered 0–7, and each block is as-

signed a size code. When you set up

your scanner to track a Type I system,

you must choose a size code for each

block. When you have chosen a size

code for all 8 blocks, you will have du-

plicated the

fleet map

for the system

you are tracking. If you have chosen

correctly, you will be able to track

transmissions in that system.

Each size code defines the number of

fleets, subfleets, and IDs each block

has. For example, you can see in the

following table that a size code of S4

has one fleet, which is divided into 16

separate subfleets, and it has a total

of 512 individual IDs.

20-432.fm Page 40 Friday, July 14, 2000 11:30 AM

Each ID in the block is unique. The

left-most digit is the block number in

the ID. The next two digits identify

which fleet is active, and the last dig-

it(s) (after the hyphen) identifies the

subfleet.

The size codes selected by a Type I

system designer depend on the spe-

cific needs of the system’s users.

Some organizations might want many

subfleets with only a few radios each,

while another organization might want

only a few subfleets, with many radios

each. To scan Type I systems, you

must select or program a fleet map

with the same size code assignments

as the trunked system. If you do this

accurately, you will track all the fleet

and subfleet combinations used by the

system. In other words, you will hear

complete communications while moni-

toring a trunked system.

Note:

www.trunkscanner.com

plans to

make preset fleet maps available as

they become known.

If you do not already know the size

codes used, you will have to guess

them. But since you do not have to fig-

ure out all the blocks at once, this is

not as hard as it seems. Select a size

code for a block, then press SEARCH.

Now listen to the communications. If

you decide you are receiving most of

the replies to the conversations with

IDs assigned to the block you just pro-

grammed, then you have probably se-

lected the right size code and can

work on the next block of the map.

There are 16 preset fleet maps to

choose from, and it is best to start with

these when setting up a Type I or hy-

brid trunk scanning bank. If none of

the following preset fleet maps allow

you to follow complete conversations,

then you probably need to program

your own fleet map (see “Program-

ming a Fleet Map” on Page 44).

Programming a Fleet Map

1. Set the scanner for conventional

scanning, then hold down TRUNK

until the scanner beeps twice.

BANK, TRUNK, and the bank

numbers flash.

2. Press a number key to select the

bank where you programmed

Type I trunk frequencies.

3. Repeatedly press ▲ or ▼ until E1

appears, then press E.

4. Press DATA.

5. Repeatedly press ▲ or ▼ until

USr appears, then press DATA.

6. Repeatedly press ▲ or ▼ to select

the size code for the first block,

then press E. The next available

block appears.

7. Repeat Step 6 until you have

selected a size code for each

block you want to work with.

8. Press SEARCH. The scanner exits

the trunking programming mode,

tunes the data channel, then

begins to search using the map

you programmed.

Note: If you select size code S12,

S13, or S14, these restrictions apply:

• S12 can only be assigned to

Blocks 0, 2, 4, or 6.

• S13 can only be assigned to

Blocks 0 and 4.

• S14 can only be assigned to Block

Since these size codes require multi-

ple blocks, you will be prompted for

the next available block when pro-

gramming a fleet map. For example, if

you assign Block 0 as an S12, the

scanner prompts you for b2, the next

block available, instead of b1. And if

you assign Block 0 as an S14, you

would not see another prompt be-

cause it uses all available blocks.

Programming a Hybrid

System

A hybrid system is simply a Type I

system with some of its blocks desig-

nated as Type II blocks. To program a

hybrid system, follow the steps listed

in “Programming a Fleet Map” on

Page 44. However, if you want a block

to be Type II, select size code S0 in

Step 6.

Programming the Base and

Offset Frequencies

To properly track Motorola VHF and

UHF trunked systems, you must pro-

gram the applicable

base

and

offset

frequencies for each system.

These settings can be found at

www.trunkscanner.com

and similar

frequency resources.

1. Set the scanner for conventional

scanning, then hold down TRUNK

until the scanner beeps twice.

2. Press the number key of the bank

where you want to store the base

frequency.

20-432.fm Page 44 Friday, July 14, 2000 11:30 AM

3. Repeatedly press ▲ or ▼ to select

E2-Hi or E2-UHF, then press E.

4. Press DATA. The preset base fre-

quency appears.

5. Enter a desired frequency, then

press

6. Press DATA. The preset offset fre-

quency appears.

7. Enter the frequency using the

number keys according to the fol-

lowing guide, then press E:

• For Motorola Type II VHF, (E2-

Hi band) use 5 kHz steps

between 5 kHz–100 kHz.

• For Motorola Type II UHF, (E2-

UHF band) use 12.5 kHz steps

between 12.5 kHz–100 kHz.

Note: For example, if you pro-

gram 406.0250 as a trunked fre-

quency, the base and offset

frequencies are as follows:

• BASE: 406.0000 MHz, OFFSET:

12.5 kHz=Channel 2

• BASE: 406.0000 MHz, OFFSET:

25.0 kHz=Channel 1

8. Repeat the steps under “Program-

ming Trunked Frequencies” on

Page 32 to store the trunked sys-

tem’s frequencies in your scan-

ner’s banks.

Turning the Motorola

Disconnect Tone Detect

Function On/Off

While trunk scanning a Motorola sys-

tem, your scanner automatically tunes

to the data channel when it detects a

disconnect tone (a code that tells the

trunking system that the transmitter

has finished sending) on the voice

channel.

You can manually turn off this function

so the scanner does not tune to the

data channel under those conditions.

Use this feature to listen to weak

transmissions when conversations are

generally disconnected.

To turn the disconnect tone detect

function off, set the scanner to trunk

track then press SVC. The scanner

beeps and flashes for about 5

seconds.

Notes:

• To set the scanner so it remains

on the voice channel (even when

a disconnect tone is transmitted or

there is no signal at all) set

SQUELCH so you hear a hissing

noise.

• You cannot use the disconnect

tone detect function if you are pro-

gramming a trunking frequency or

a fleet map.

To set the scanner to automatically

tune to the data channel once again

when it detects a disconnect tone,

press

SVC. disappears.

PC REMOTE FUNCTION

Your scanner’s PC Remote function

lets you connect the scanner to a

computer then use the computer to

operate most of the scanner’s func-

tions, the same way as if you were us-

ing the keys on the scanner’s front

panel.

CONNECTING THE

SCANNER TO A

COMPUTER

Caution: Always turn off the computer

before connecting or disconnecting

your scanner. Otherwise you could

damage your computer or the scan-

ner.

To connect the scanner to your com-

puter, plug one end of an optional 9-

pin serial cable (available at your local

RadioShack store) into REMOTE on

the back of the scanner, then plug the

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

National Weather Frequencies

Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals created inside the scan-

ner’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. This scanner’s birdie frequencies (in MHz) are:

To find the birdies in your individual 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 search every fre-

quency 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 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

TROUBLESHOOTING

If your scanner is not working as it should, these suggestions might help you elimi-

nate the problem. If the scanner still does not operate properly, take it to your local

RadioShack store for assistance.

PROBLEM POSSIBLE CAUSE REMEDY

Scanner is on but will not

scan. SQUELCH is not correctly

adjusted. Adjust SQUELCH clock-

wise.

Only one channel or no

channels are stored. Store frequencies into more

than one channel.

Scanner is totally inopera-

tive. No power. Make sure the scanner is

plugged into a working AC

or DC outlet.

The AC or DC adapter is not

connected. Be sure the adapter’s barrel

plug is fully inserted into the

DC 12V jack.

The scanner must be reset. Reset the scanner (see

“Resetting the Scanner” on

Page 66).

Poor or no reception An antenna is not con-

nected or connected incor-

rectly.

Make sure an antenna is

connected to the scanner.

Error appears. Programming error. Reprogram the frequency

correctly, including the deci-

mal point.

In the scan mode, the scan-

ner locks on frequencies

that have an unclear trans-

mission.

Programmed frequencies

are the same as “birdie” fre-

quencies.

Avoid programming fre-

quencies listed under

“Birdie Frequencies” on

Page 55 or only listen to

them manually.

Scanner will not track a

trunked system. The transmission might not

use a system that can be

tracked by your scanner.

Scan another transmission.

The data frequency is miss-

ing. Find the data frequency

(see “Programming Trunked

Frequencies” on Page 32).

20-432.fm Page 64 Friday, July 14, 2000 11:30 AM

Scanner will not track a

trunked system

(continued)

The system you are trying

to track is a Type I System,

and the scanner is set to

scan Type II systems.

Set the scanner to receive

Type I trunked frequencies.

See “Scanning Type I and

Hybrid Trunked Systems”

on Page 40.

Scanner will not stop while

scanning a scan list The IDs you have stored

are not active. Scan another transmission.

Scanner will not acquire a

data channel Squelch is not correctly

adjusted. See “Setting Squelch for the

Trunk Scanning Mode” on

Page 31.

The frequency used for the

data channel is missing. Add the frequency used for

the data channel to the fre-

quency list. See “Program-

ming Trunked Frequencies”

on Page 32.

Missing replies to conversa-

tions The system you are trying

to track is a Type I system,

and the scanner is set to

scan Type II systems.

Set the scanner to receive

Type I trunked frequencies.

See “Scanning Type I and

Hybrid Trunked Systems”

on Page 40.

The selected fleet map is

incorrect. Try another preset fleet map

or program your own fleet

map. See “Scanning Type I

and Hybrid Trunked Sys-

tems” on Page 40.

Not all of the trunk’s fre-

quencies have been

entered.

Enter all of the trunk’s fre-

quencies.

Channel activity indicators

are lighting but no sound is

heard.

The transmission might be a

private or telephone inter-

connect call. The scanner

does not scan these types

of transmissions.

Scan for another transmis-

sion.

The ID is locked out. Unlock the ID (see “Unlock-

ing a Single ID” on Page 36

or “Unlocking All IDs” on

Page 36).

RESETTING THE

SCANNER

You might need to reset the scanner

if:

• the scanner’s display locks up.

• the scanner does not work prop-

erly after you connect power.

• the scanner is dropped or sub-

jected to a physical or electrical

shock.

Caution:

This procedure clears all the

information you have programmed

into the scanner. Use this procedure

only when you are sure your scanner

is not working properly.

To reset the scanner, turn it off. Then,

while you hold down 2 and 9, turn on

the scanner. CLEAr appears for

about 5 seconds while the scanner re-

sets.

Caution: Do not turn off the scanner

while it is resetting.

CARE AND MAINTENANCE

Your RadioShack PRO-2052 1000-Channel Dual Trunking TrunkTracker Home

Scanner is an example of superior design and craftsmanship. The following sug-

gestions 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.
