FEATURES

Your new RadioShack PRO-90 300-Channel Trunk-

Tracker Scanner is the first of a new generation of scan-

ners designed to track MotorolaType I and Type II

(such as Smartnet, and Privacy Plus) and hybrid an-

alog trunking systems, which are extensively used in

many 800 MHz communication systems.

Trunking communications systems let a large group of 2-

way radio users (or even different groups of 2-way radio

users) efficientlyuse a large range offrequencies. Instead

of selecting a specific frequency for a transmission, the 2-

way radio user simply selects a talk group. The trunking

system automatically transmits the call on the first avail-

able frequency, and also sends a code that uniquely iden-

tifies that 2-way radio user’s transmission on a different

frequency called a data channel.

Since the trunking system might send individual 2-way ra-

dio user’s calls and response transmissions on different

frequencies, it is difficult to listen to trunked communica-

tions using a regular scanner. The PRO-90 lets you select

and monitor the data channel frequency sent with a 2-way

radio user’s transmission, so you can hear the call and re-

sponse for that 2-way radio user and 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 31,000 excit-

ing frequencies, including police and fire departments,

ambulance services, and amateur radio services, and you

can change your selection at any time.

Your scanner also has these special features:

Triple-Conversion Circuitry — virtually eliminates any

interference from IF (intermediate frequency) images, so

you hear only the selected frequency.

Ten Channel-Storage Banks — let you store 30 chan-

nels in each bank to group channels so you can more

easily identify calls.

Five Scan Lists — let you store up to 50 IDs in each

tracking bank (up to a total of 500).

Two-Second Scan Delay — delays scanning for about

2 seconds before moving to another channel, so you can

hear more replies that are made on the same channel.

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.

Priority Channels — lets you program one channel in

each bank (10 in all) and then have the scanner check it

every 2 seconds so you don't miss transmissions on

those channels.

Five Service-Search Banks — lets you search preset

frequencies in separate police, fire/emergency, aircraft,

marine, and weather banks, to make it easy to locate

specific types of calls.

HyperSearch and HyperScan — lets you set the

scanner to search at up to 300 steps per second and

scan at up to 100 frequencies per second in frequency

bands with 5 kHz steps, to help you quickly find interest-

ing broadcasts. 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 searches. This lets

the scanner avoid non-voice signals, making a search

faster.

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

prevent accidental changes to the scanner's program-

ming.

Manual Access — lets you directly access any channel.

Liquid-Crystal Display — makes it easy to view and

change programming information.

Display Backlight — makes the scanner easy to read in

low-light situations.

20-520.fm Page 3 Wednesday, August 4, 1999 3:06 PM

Flexible Antenna with BNC Connector — provides ex-

cellent reception and is designed to help prevent anten-

na breakage. Or, you can connect an external antenna.

Memory Backup — keeps the frequencies stored in

memory for an extended time.

Three Power Options — let you power the scanner us-

ing the built-in rechargeable battery pack, external AC

power using the supplied AC adapter/charger, or DC

power using an optional DC cigarette-lighter power ca-

ble.

Key Confirmation Tones — the scanner sounds a tone

when you perform an operation correctly, and an error

tone if you make an error.

Battery Low Alert — warns you when battery power

gets low.

Battery Save — saves battery power when the scanner

does not detect any transmissions for more than 1

minute when a channel is manually selected.

Your 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 interference 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 differ-

ent electrical circuit 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 including police and fire departments, ambulance

services, government agencies, private companies, am-

ateur radio services, military operations, pager services,

and wireline (telephone and telegraph) serviceproviders.

It islegal to listen to almost every transmission yourscan-

ner can receive. However, there are some transmissions

you should never intentionally listen to. These include:

• Telephone conversations (either cellular, cordless,

or other private means of telephone signal transmis-

sion)

• Pager transmissions

• Any scrambled or encrypted transmissions

According to the Electronic Communications Privacy Act

(ECPA), you are subject to fines and possible imprison-

ment for intentionally listening to, using, or divulging the

contents of such a transmission unless you have the

consent of a party to the conversation (unless such ac-

tivity is otherwise illegal). We encourage responsible, le-

gal scanner use.

PREPARATION

POWER SOURCES

You can power your scanner from any of three sources:

• Built-in rechargeable battery pack

• Standard AC power using the supplied AC adapter/

charger

• Vehicle battery power using an optional DC ciga-

rette-lighter power cable

Using the Rechargeable Battery Pack

You must charge your scanner’s built-in rechargeable

battery pack before you can use it to power the scanner.

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

charge the rechargeable battery pack while it is in the

scanner.

To charge the battery pack, simply connect the supplied

AC adapter/charger or an optional DC cigarette-lighter

power cable to the scanner’s EXT. PWR jack. See “Using

Standard AC Power” on Page 9 or “Using Vehicle Bat-

tery Power” on Page 10.

It takes about 14–16 hours to recharge a battery pack

that is fully discharged. (You can operate the scanner

while recharging the battery pack, but charging takes

longer).

Notes:

• The scanner automatically stops charging the bat-

tery pack when it is fully charged, even if the sup-

plied AC adapter/charger or a DC cigarette-lighter

power cable is still connected to the scanner.

• A rechargeable battery pack lasts longer and deliv-

ers more power if you occasionally let it fully dis-

charge. To do this, simply use the scanner until the

low battery indicator appears. Then fully charge the

battery pack.

If the battery pack doesn’t power the scanner even after

you charge it, you must replace it. You can order a re-

placement battery pack from your local RadioShack

store.

20-520.fm Page 8 Wednesday, August 4, 1999 3:06 PM

1. Press down on the battery compartment cover and

slide the cover in the direction of the arrow to

remove it.

2. Disconnect the battery pack’s connector from the

scanner’s connector. Then remove the battery pack

from the battery compartment.

3. Attach the new battery pack's connector to the bat-

tery socket inside the battery compartment. Then

put the battery pack into the compartment.

4. Replace the cover.

When the scanner’s battery gets low, blinks and

the scanner beeps about every 15 seconds.

Important: At the end of a rechargeable battery pack's

useful life, it must be recycled or disposed of properly.

Contact your local, county, or state hazardous waste

management authorities for information on recycling or

disposal programs in your area. Some options that might

be available are: municipal curb-side collection, drop-off

boxes at retailers such as your local RadioShack store,

recycling collection centers, and mailback programs.

Using Standard AC Power

To power the scanner from AC power, use the supplied

AC adapter/charger. Plug the adapter/charger's barrel

plug into the scanner's EXT. PWR jack. Then plug the AC

adapter/charger's power module into a standard AC out-

let.

20-520.fm Page 9 Wednesday, August 4, 1999 3:06 PM

Warning: Do not use the AC adapter/charger's polarized

plug with an extension cord, receptacle, or other outlet

unless the blades can be fully inserted to prevent blade

exposure.

Caution: Use only the supplied AC adapter/charger. It is

specifically designed for this scanner.

Using Vehicle Battery Power

To power the scanner from your vehicle's cigarette-light-

er socket, you need a DC cigarette-lighter power cable,

such as Cat. No. 270-031.

Cautions:

• The DC cigarette-lighter power cable must be capa-

ble of delivering 12 volts, its center tip must be set to

positive, and its barrel plug must correctly fit the

scanner's EXT. PWR jack. The recommended power

cable meets these specifications. Using a power

cable that does not meet these specifications could

damage the scanner or the power cable.

• To protect your vehicle's electrical system, always

plug the power cable into the scanner before you

plug it into your vehicle's cigarette-lighter socket.

Always unplug the power cable from the vehicle's

cigarette-lighter socket before you unplug it from the

scanner.

• Insert the DC cigarette-lighter power cable's barrel

plug into the EXT. PWR jack, then plug the power

EXT. PWR Jack

cable's other end into your vehicle's cigarette-lighter

socket.
