Features

Your RadioShack Handheld Scanner is one of a new

generation of scanners designed to track Motorola® Type

I and Type II (such as Smartnet® and Privacy Plus®) and

hybrid analog trunking systems, plus GE/Ericsson

(EDACS®) and EF Johnson (LTR®) type systems, which

are extensively used in many communication 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 set of frequencies. Instead of se-

lecting a specific frequency for a transmission, the user

simply selects a talk group. The trunking system auto-

matically transmits the call on the first available frequen-

cy, and also sends a code that uniquely identifies that

transmission.

Since the trunking system might send a call and its re-

sponse on different frequencies, it is difficult to listen to

trunked communications using a regular scanner. The

scanner monitors the data sent with a 2-way radio trans-

mission, so you can hear the call and response for that

user and more easily “follow” the conversation.

The scanner also lets you scan conventional transmis-

sions, and is preprogrammed 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

complicated programming.

This scanner gives you direct access to over 33,000 fre-

quencies including those used by police and fire depart-

ments, ambulance services, government agencies, air,

and amateur radio services.

Your scanner includes these features:

Simultaneous Trunking Operation — tracks three

trunking systems (LTR, Motorola, and EDACS) and con-

ventional systems at the same time.

10 Channel-Storage Banks — let you store 50 chan-

nels in each bank (500 channels) to group channels so

calls are easier to identify.

20-522b.fm Page 5 Thursday, September 7, 2000 9:41 AM

6Features

12-Character, 4-Line, Dot-Matrix Display — shows

you detailed operating information and lets you easily

program the scanner.

Weather Alert — automatically sounds the alarm tone to

advise of hazardous weather conditions when it detects

the alert signal on the local National Oceanic and Atmo-

spheric Administration (NOAA) weather channel during

priority operation.

Digital Weather Alert — displays the weather event text

so you can see the reason for the alert.

Preprogrammed Frequency Ranges — let you search

for transmissions within preset frequency ranges or with-

in ranges you set, to reduce search time and select inter-

esting frequencies more quickly.

Subaudible Tone Decode — decodes and displays the

Continuous Tone Coded Squelch System (CTCSS) tone

signal being transmitted.

Digital Subaudible Tone Decode — decodes and dis-

plays the Digital Coded Squelch (DCS) being received.

Data Cloning — lets you transfer the programmed data

to another PRO-92 scanner. You can also upload or

download the programmed data to or from a PC using

an optional interface kit.

Triple Conversion Superheterodyne Receiver — vir-

tually eliminates any interference from intermediate fre-

quency (IF) images, so you hear only the frequency you

select.

HyperscanTM and HypersearchTM — the scanner scans

at up to 25 channels per second and searches at up to

50 steps per second, to help you quickly find interesting

transmissions.

Scan Delay — delays scanning for about 2 seconds be-

fore moving to another channel in conventional mode, so

you can hear more replies that are made on the same

channel.

20-522b.fm Page 6 Thursday, September 7, 2000 9:41 AM

Features

Priority Channel — you can set the scanner to check

one channel every 2 seconds so you do not miss impor-

tant calls.

Signal Attenuation (Attenuate) — lets you program

each memory location to reduce the scanner’s sensitivity

to strong local signals, to reduce interference or noise

caused by these signals.

Text Input — lets you input a text label for each chan-

nel, talk group ID, bank, or other memory location so you

can easily know about the transmission you are hearing.

Lock Out Function — lets you set your scanner to skip

over specified channels or frequencies when scanning

or searching, and skip over IDs when tracking trunked

systems.

Key Lock — lets you lock the scanner’s keys to help

prevent accidentally changing the scanner’s program-

ming.

Flexible Antenna with BNC Connector — provides ex-

cellent reception and is designed to help prevent anten-

na breakage.

Memory Backup — keeps the frequencies stored in

memory for an extended time even without internal bat-

teries.

Three Power Options — let you power the scanner with

internal batteries (non-rechargeable batteries or re-

chargeable batteries). You can also use an AC adapter

(not supplied) or power the scanner in a vehicle using a

DC adapter (not supplied).

Supplied Police Call Trunking Guide — provides a

quick reference to public safety trunking radio systems in

the United States.

Your scanner can receive these frequencies:

• 29–54 MHz

• 108–136.9875 MHz

• 137–174 MHz

20-522b.fm Page 7 Thursday, September 7, 2000 9:41 AM

8Features

• 380–512 MHz

• 806–823.9875 MHz

• 849–868.9875 MHz

• 894–960 MHz

This Owner’s Manual also includes the section “A Gen-

eral Guide to Scanning” on Page 58 to help you target

frequency ranges in your service area so you can search

for a wide variety of transmissions.

FCC NOTICE

Your scanner might cause TV or radio interference even

when it is operating properly. To determine whether your

scanner is causing the interference, turn off your scan-

ner. If the interference goes away, your scanner is caus-

ing the interference. Try the following methods to

eliminate the interference.

• Move your scanner away from the TV or radio.

• Connect your scanner to an outlet that is on a differ-

ent electrical circuit from the TV or radio.

• Contact your local RadioShack store for help.

If you cannot eliminate the interference, the FCC re-

quires that you stop using your scanner.

This device complies with Part 15 of the

FCC Rules

. Op-

eration is subject to the following conditions: (1) this de-

vice must not cause harmful interference, and (2) this

device must accept any interference received, including

interference that may cause undesired operation.

Note: Mobile use of this scanner is unlawful or requires

a permit in some areas. Check the laws in your area.

SCANNING LEGALLY

Scanning is a fun and interesting hobby. You can hear

police and fire departments, ambulance services, gov-

ernment agencies, private companies, amateur radio

services, aircraft, and military operations. It is legal to lis-

20-522b.fm Page 8 Thursday, September 7, 2000 9:41 AM

9

Preparation

ten to almost every transmission your scanner can re-

ceive. However, there are some electronic and wire

communications that are illegal to intentionally intercept.

These include:

• telephone conversations (cellular, cordless, or other

private means of telephone signal transmission)

• pager transmissions

• scrambled or encrypted transmissions

According to the

Federal Electronic Communications Pri-

vacy Act

(ECPA), as amended, you could be fined and

possibly imprisoned for intentionally listening to, using,

or disclosing the contents of such a transmission unless

you have the consent of a party to the communication

(unless such activity is otherwise illegal). These laws

change from time to time and there might be state or lo-

cal laws that also affect legal scanner usage.

ˆ

Preparation

POWER SOURCES

You can power your scanner from any of three sources:

• internal non-rechargeable batteries or rechargeable

batteries (not supplied — see “Using Batteries” on

Page 10)

• standard AC power (with an optional AC adapter —

see “Using AC Power” on Page 13)

• vehicle power (with an optional DC adapter — see

“Using Vehicle Power” on Page 14)

Notes:

• Connecting an AC or DC adapter to the scanner dis-

connects internal batteries when you use the sup-

plied non-rechargeable battery holder, but it does

not disconnect internal batteries when you use the

supplied rechargeable battery holder.

20-522b.fm Page 9 Thursday, September 7, 2000 9:41 AM

10 Preparation

• If you install the rechargeable battery holder, you

can operate the scanner and recharge the

rechargeable batteries at the same time. See “Using

Batteries” below and “Charging Rechargeable Bat-

teries” on Page 12.

• If the scanner stops working properly after connect-

ing it to power, try resetting it. See “Resetting/Initial-

izing the Scanner” on Page 67.

Using Batteries

You can power the scanner with six AA batteries. For the

longest operation and best performance, we recommend

alkaline batteries, available at your local RadioShack

store.

You can use either the supplied non-rechargeable black

battery holder, or the supplied rechargeable yellow bat-

tery holder. If you use the rechargeable battery holder,

we recommend RadioShack nickel-cadmium or nickel-

metal hydride batteries.

Warning: Never install non-rechargeable batteries in the

rechargeable yellow battery holder. Non-rechargeable

batteries can get hot or explode if you try to recharge

them.

Note: You must charge rechargeable batteries before

you use them the first time. See “Charging Recharge-

able Batteries” on Page 12.

Follow these steps to install the batteries.

1. Press down on the battery compartment cover on

the bottom of the scanner and slide the cover in the

direction of the arrow to remove it.

2. Pull out and slide the battery holder out of the bat-

tery compartment.

20-522b.fm Page 10 Thursday, September 7, 2000 9:41 AM

11

Preparation

3. Insert six AA batteries in the battery holder as indi-

cated by the polarity symbols (+ and –) marked on

the holder.

Cautions:

• Use only fresh batteries of the required size and

recommended type.

• Always remove old or weak batteries. Batteries

can leak chemicals that destroy electronic cir-

cuits.

• Do not mix old and new batteries, different types

of batteries (alkaline or rechargeable), or

rechargeable batteries of different capacities.

4. Slide the battery holder into the compartment.

20-522b.fm Page 11 Thursday, September 7, 2000 9:41 AM

12 Preparation

Caution: The battery holder fits only one way. Do

not force it.

5. Replace the cover.

When battery power is low, Low Battery! appears

and the scanner beeps continuously. When battery pow-

er is depleted, the scanner turns itself off. Replace all six

non-rechargeable batteries, or recharge the recharge-

able batteries. See “Charging Rechargeable Batteries.”

Warning: Always dispose of old batteries promptly and

properly. Do not bury or burn them.

Caution: If you do not plan to use the scanner with bat-

teries for a month or longer, remove the batteries. Batter-

ies can leak chemicals that can destroy electronic parts.

Charging Rechargeable Batteries

Your scanner has a built-in charging circuit that lets you

charge rechargeable batteries (not supplied) while it is in

the scanner. To charge rechargeable batteries connect

an appropriate AC or DC adapter to the PWR DC 9V jack.

We recommend RadioShack rechargeable batteries.

Note: To charge batteries with a DC adapter from a DC

power source, you must use RadioShack Cat. No. 273-

1825 and a size H Adaptaplug® (neither supplied) avail-

able at your local RadioShack store. Make sure the

adapter’s voltage is set to 10V.

It takes between 14–16 hours to recharge rechargeable

batteries that are fully discharged. You can operate the

scanner while recharging the rechargeable batteries, but

charging takes longer.

Notes:

• The scanner can charge Ni-MH batteries, however,

these batteries require more than 24 hours to

charge. We recommend using an external quick

charger for Ni-MH batteries.

• Additional charging time is required for high-

capacity rechargeable batteries.

20-522b.fm Page 12 Thursday, September 7, 2000 9:41 AM

13

Preparation

• Rechargeable batteries last longer and deliver more

power if you let them fully discharge once a month.

To do this, use the scanner until Low Battery!

appears. Then fully charge the rechargeable batter-

ies.

Important: .The EPA certified RBRC® Bat-

tery Recycling Seal on the nickel-cadmium

(Ni-Cd) battery indicates RadioShack is

voluntarily participating in an industry pro-

gram to collect and recycle these batteries

at the end of their useful life, when taken out of service in

the United States or Canada. The RBRC program pro-

vides a convenient alternative to placing used Ni-Cd bat-

teries into the trash or the municipal waste stream, which

may be illegal in your area. Please call 1-800-THE-

SHACK (1-800-843-7422) for information on Ni-Cd bat-

tery recycling and disposal bans/restrictions in your ar-

ea. RadioShack’s involvement in this program is part of

the company’s commitment to preserving our environ-

ment and conserving our natural resources.

Using AC Power

You can power the scanner using an 9V, 300 mA AC

adapter and a size H Adaptaplug (neither supplied). We

recommend RadioShack Cat. No. 273-1767 (available at

your local RadioShack store).

Cautions:

You must use a Class 2 power source that

supplies 9V DC and delivers at least 300

mA. Its center tip must be set to negative

and its plug must fit the scanner's PWR DC 9V jack.

Using an adapter that does not meet these specifi-

cations 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,

disconnect the adapter from AC power before you

disconnect it from the scanner.

Follow these steps to connect the adapter.

1. Connect the Adaptaplug to the adapter’s cord with

the tip set to negative.

!

20-522b.fm Page 13 Thursday, September 7, 2000 9:41 AM

14 Preparation

2. Plug the adapter’s barrel plug into the scanner’s

PWR DC 9V jack.

3. Plug the adapter into a standard AC outlet.

Using Vehicle Power

You can power the scanner from a vehicle’s 12V power

source (such as a cigarette-lighter socket) using a 9V,

300 mA DC adapter and a size H Adaptaplug (neither

supplied). We recommend RadioShack Cat. No. 273-

1810 (available at your local RadioShack store).

Note: For charging batteries with an optional DC adapter

from a DC power source, use RadioShack Cat. No. 273-

1825 and a size H Adaptaplug (available at your local

RadioShack store). Make sure the adapter’s voltage is

set to 10V.

Cautions:

You must use a power source that sup-

plies 9V DC and delivers at least 300 mA.

Its center tip must be set to negative and

its plug must fit the scanner's PWR DC 9V jack. Us-

ing an adapter that does not meet these specifica-

tions could damage the scanner or the adapter.

• Always connect the DC adapter to the scanner

before you connect it to the power source. When

you finish, disconnect the adapter from the power

source before you disconnect it from the scanner.

Follow these steps to connect the adapter.

1. Connect the Adaptaplug to the adapter’s cord with

the tip set to negative.

2. Plug the adapter’s barrel plug into the scanner’s

PWR DC 9V jack.

!

20-522b.fm Page 14 Thursday, September 7, 2000 9:41 AM

15

Preparation

3. Plug the adapter’s cigarette-lighter plug into your

vehicle’s cigarette-lighter socket.

Note: If the scanner does not operate properly when you

connect a DC adapter, unplug the DC adapter from the

cigarette-lighter socket and clean the socket to remove

ashes and other debris.

CONNECTING THE ANTENNA

Follow these steps to attach the supplied flexible anten-

na to the ANT jack on the top of your scanner.

1. Align the slots around the antenna’s connector with

the tabs on the ANT jack.

2. Press the antenna down over the jack and turn the

antenna’s base clockwise until it locks into place.

Connecting an Optional Antenna

The antenna connector on your scanner makes it easy

to use the scanner with a variety of antennas, such as an

external mobile antenna or outdoor base station anten-

na. Your local RadioShack store sells a variety of anten-

nas.

20-522b.fm Page 15 Thursday, September 7, 2000 9:41 AM

16 Preparation

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,

you will also need a BNC adapter (also available at your

local RadioShack store).

Follow the installation instructions supplied with the an-

tenna, route the antenna cable to the scanner, then con-

nect it to the ANT jack.

Warning: Use extreme caution when installing or re-

moving an outdoor antenna. If the antenna starts to fall,

let it go! It could contact overhead power lines. If the an-

tenna touches a power line, contact with the antenna,

mast, cable or guy wires can cause electrocution and

death! Call the power company to remove the antenna.

Do not attempt to do so yourself.

CONNECTING AN EARPHONE/

HEADPHONES

For private listening, you can plug an earphone or mono/

stereo headphones (not supplied), available at your local

RadioShack store, into the jack on top of your scan-

ner. This automatically disconnects 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 perma-

nent hearing loss.

20-522b.fm Page 16 Thursday, September 7, 2000 9:41 AM

17

Preparation

• Set the volume to the lowest setting before you

begin listening. After you begin listening, adjust the

volume to a comfortable level.

• Once you set the volume, do not increase it. Over

time, your ears adapt to the volume level, so a vol-

ume level that does not cause discomfort might still

damage your hearing.

Traffic Safety

Do not wear an earphone or headphones while you drive

a vehicle or ride a bicycle. This can create a traffic haz-

ard and can be illegal in some areas.

Even though some earphones and headphones let you

hear some outside sounds when you listen at normal

levels, they still can present a traffic hazard.

CONNECTING AN EXTENSION

SPEAKER

In a noisy area, an amplified speaker (not supplied),

available at your local RadioShack store, might provide

more comfortable listening. Plug the speaker cable’s 1/8-

inch (3.5-mm) mini-plug into your scanner’s jack.

Note: You must use an amplified speaker with this scan-

ner. Non-amplified speakers do not provide sufficient

volume for comfortable listening.

USING THE BELT CLIP

You can use the belt clip attached to the back of the

scanner for hands-free carrying when you are on the go.

Slide the belt clip over your belt or waistband.

20-522b.fm Page 17 Thursday, September 7, 2000 9:41 AM

18 About Your Scanner

CONNECTING THE CLONE CABLE

You can transfer the programmed data to and from an-

other PRO-92 or PRO-2067 using the supplied clone ca-

ble. Connect the cable between each scanner’s PC/IF

jacks. See “Cloning the Programmed Data from Scanner

to Scanner” on Page 48. You can also upload or down-

load the programmed data to or from a PC using an op-

tional PC interface kit available by special order from

your local RadioShack store.

ˆ

About Your Scanner

Once you understand a few simple terms used in this

manual and familiarize yourself with your scanner’s fea-

tures, you can put the scanner to work for you. You sim-

ply determine the type of communications you want to

receive, then set the scanner to scan them.

A

frequency

is the receiving signal location (expressed in

kHz or MHz). To find active frequencies, you can use the

search function.

You can also search the SEARCH banks, which are pre-

programmed frequencies in the scanner’s memory (see

“Searching a Preprogrammed Frequency Range” on

Page 34 for the frequency list). You can change the

SEARCH frequency ranges.

When you find a frequency, you can store it into a pro-

grammable 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. See “Trunk-

ing Operation” on Page 48 for terms related to trunking

systems.
