FEATURES

Your RadioShack PRO-92 500-Channel Portable Trunk-

ing Scanner is one of a new generation of scanners de-

signed 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 automat-

ically transmits the call on the first available frequency,

and also sends a code that uniquely identifies that trans-

mission.

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

PRO-92 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 special features:

Simultaneous Trunking Operation — tracks three

trunking systems, LTR, Motorola, and EDACS at the

same time, as well as conventional systems.

Text Input — lets you input a text label for each channel,

talk group ID, bank, or other memory so you can easily

know about the transmission you are hearing.

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.

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

detailed operating information and lets you easily pro-

gram the scanner.

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.

10 Channel-Storage Banks — let you store 50 channels

in each bank to group channels so calls are easier to

identify.

Triple Conversion Superheterodyne Receiver — virtu-

ally 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.

20-522.fm Page 3 Friday, September 17, 1999 12:46 PM

60 Preprogrammed Frequency Ranges — let you

search for transmissions within preset frequency ranges

or within ranges you set, to reduce search time and select

interesting frequencies more quickly.

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.

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 to reduce the scanner’s sensitivity to strong

local signals, to reduce interference or noise caused by

these signals.

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.

Weather SAME Decode — displays the weather event

text so you can see the reason for the alert.

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 sys-

tems.

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

vent accidentally changing the scanner’s programming.

Flexible Antenna with BNC Connector — provides ex-

cellent reception and is designed to help prevent antenna

breakage.

Memory Backup — keeps the frequencies stored in

memory for an extended time even without a battery.

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 PRO-92 scanner can receive these frequencies:

• 29–54 MHz

• 108–136.9875 MHz

• 137–174 MHz

• 380–512 MHz

• 806–823.9875 MHz

• 849–868.9875 MHz

• 894–960 MHz

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

al Guide to Scanning” on Page 65 to help you target fre-

quency 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 scanner.

If the interference goes away, your scanner is causing

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.

20-522.fm Page 5 Friday, September 17, 1999 12:46 PM

If you cannot eliminate the interference, the FCC requires

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, govern-

ment agencies, private companies, amateur radio servic-

es, aircraft, and military operations. It is legal to listen to

almost every transmission your scanner can receive.

However, there are some electronic and wire communi-

cations that are illegal to intentionally intercept. These in-

clude:

• 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 local laws

that also affect legal scanner usage.

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”)

• standard AC power (with an optional AC adapter —

see “Using AC Power” on Page 14)

• vehicle power (with an optional DC adapter — see

“Using Vehicle Power” on Page 15)

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 sup-

plied rechargeable battery holder.

• 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 Batteries” on

Page 13.

• If the scanner stops working properly after connect-

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

izing the Scanner” on Page 75.

Using Batteries

You can power the PRO-92 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.
