INTRODUCTION

Your new RadioShack PRO-70 50-Channel Portable

Scanner lets you in on all the action. This scanner gives

you direct access to over 22,000 exciting frequencies, in-

cluding police and fire departments, ambulance services,

and amateur radio services. You can select up to 50 chan-

nels to scan, and you can change your selection at any

time.

The secret to your scanner’s ability to scan so many fre-

quencies is its custom-designed microprocessor — a tiny,

built-in computer. Your scanner also has these special

features:

Ten Preprogrammed Search Bands — let you search

for transmissions within preset frequency ranges, so you

can find interesting frequencies more quickly.

Ten Preprogrammed Weather Frequencies — keep

you informed about current weather conditions.

Two-Second Automatic Scan Delay — delays scanning

for 2 seconds before moving to another channel, so you

can hear more replies.

50 Channels — let you store up to 50 of your favorite fre-

quencies for easy recall and scanning.

Monitor Memory — lets you temporarily save an active

frequency you locate during a direct search, until you de-

cide whether or not you want to save it into a channel.

Memory Backup — keeps the channel frequencies

stored in memory for about 1 hour during a power loss.

Channel Lockout — keeps channels you select from be-

ing scanned.

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.

Liquid Crystal Display — makes it easy to view and

change programming information.

Display Backlight — makes the scanner easy to read in

low light situations.

Three Power Options — let you power the scanner from

internal batteries (non-rechargeable batteries or a re-

chargeable scanner battery pack) or external AC or DC

power (using optional adapters).

We recommend you record your scanner’s serial number

here. This number is on the scanner’s back panel.

Your PRO-70 scanner contains the following prepro-

grammed frequencies (divided into search bands). See

“Using Band Search” on Page 25.

In addition, your scanner is preprogrammed with the fol-

lowing weather service frequencies:

This owner’s manual also includes the section “A General

Guide to Scanning,” which helps you target frequency

ranges in your service area so you can search for a wide

variety of broadcasts.

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

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 andthere might be state orlocallaws that also

affect legal scanner usage.

PREPARATION

POWER SOURCES

You can power your scanner from any of three sources:

• Internal batteries or a rechargeable scanner battery

pack (not supplied — see “Using Batteries”)

• Standard AC power (with an optional AC adapter —

see “Using Standard AC Power” on Page 11)

• Vehicle battery power (with an optional DC adapter

— see “Using Vehicle Battery Power” on Page 12)

Notes:

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

connects any internal batteries, but it does not dis-

connect a rechargeable battery pack. If you install a

rechargeable battery pack, you can operate the

scanner and recharge the battery pack at the same

time. See “Using Batteries” and “Charging a

Rechargeable Battery Pack” 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 49.

Using Batteries

You can power your scanner from sixAA batteries.For the

longest operation and best performance, we recommend

alkaline batteries, such as RadioShack Cat. No. 23-552.

You can also power the scanner from a rechargeable

scanner battery pack, such as Cat. No. 23-288.

Note: You can also use six rechargeable nickel-cadmium

batteries (such as Cat. No. 23-125) to power the scanner.

To charge or recharge nickel-cadmium batteries, howev-

er, you must remove them from the scanner and use an

external charger (such as Cat. No. 23-134).

20-310.fm Page 9 Wednesday, August 4, 1999 10:49 AM

Follow these steps to install batteries or a battery pack.

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 up and slide the battery holder or battery pack

out of the battery compartment.

3. If you are installing individual batteries, insert six bat-

teries in the battery holder as indicated by the polar-

ity symbols (+ and –) marked on the battery holder.
