The Basics 4

The FCC wants you to know

This equipment has been tested and found to comply with the limits for a

Class B digital device, pursuant to Part 15 of the FCC Rules. These limits

are designed to provide reasonable protection against harmful interference

in a residential installation. This equipment generates, uses, and can

radiate radio frequency energy and, if not installed and used in accordance

with the instructions, may cause harmful interference to radio

communications.

However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause harmful interference to

radio or television reception, which can be determined by turning the

equipment off and on, the user is encouraged to try to correct the

interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Consult your local RadioShack store or an experienced radio/TV

technician for help.

• If you cannot eliminate the interference, the FCC requires that you stop

using your scanner.

Changes or modifications not expressly approved by RadioShack may

cause interference and void the user’s authority to operate the equipment.

You must use shielded interface cables with this equipment.

This device complies with Part 15 of the FCC Rules. Operation is subject to

the following two conditions: (1) this device may not cause harmful

interference, and (2) this device must accept any interference received,

including interference that may cause undesired operation.

5 The Basics

powering your scanner

You can power your scanner from any of three

sources:

• internal batteries (not supplied)

• standard AC power (using an optional

AC adapter)

• vehicle battery power (using an optional

DC adapter)

Before installing batteries, set the switch in the

battery compartment to match the type of batteries

you will use. Select RECHARGEABLE for all

non-alkaline battery types, including lithium, Ni-Cd

and Ni-MH.

Remove battery cover and set battery switch.

The Basics 6

Install 2 AA batteries, matching the polarity

symbols (+ -).

Replace the cover.

7 The Basics

Warning: Set ALKALINE/RECHARGEABLE to

RECHARGEABLE for use only with nickel cadmium

(Ni-Cd) or nickel metal hydride (Ni-MH) rechargeable

batteries. Never attempt to recharge non-

rechargeable batteries. Non-rechargeable batteries

can get hot or explode if you try to recharge them.

Cautions:

• Use only fresh batteries of the required size and

recommended type.

• Do not mix batteries of different capacities or

different chemistries.

• Always remove old or weak batteries. Batteries

can leak chemicals that destroy electronic

circuits.

When flashes and the scanner beeps every 15

seconds, replace both batteries.

Warning: Always dispose of old batteries promptly

and properly. Do not bury or burn them.

using rechargeable batteries

You can also use two rechargeable batteries to

power your scanner. Before you use Ni-Cd or Ni-MH

batteries, you must charge them.

The scanner has a built-in circuit that lets you

recharge Ni-Cd or Ni-MH batteries while they are in

the scanner. To charge the batteries, set ALKALINE/

The Basics 8

RECHARGEABLE inside the battery compartment to

RECHARGEABLE, install the batteries in the scanner,

and connect an external AC or DC adapter to the

scanner's DC 6V jack (see “using AC power” on

Page 10 or “using vehicle battery power” on

Page 11).

Warning: Do not connect either the AC or DC

adapter to the scanner if non-rechargeable batteries

(such as alkaline batteries) are installed in the scan-

ner and ALKALINE/RECHARGEABLE is set to

RECHARGEABLE, or if you are unsure of the

switch's position. Non-rechargeable batteries will

get hot and can even explode if you try to recharge

them.

Before you use Ni-Cd or Ni-MH batteries for the first

time, charge them for 14 hours to bring them to a

full charge.

Discharged batteries take about 14 hours to fully

recharge.

Notes:

• Ni-Cd batteries last longer and deliver more

power if you occasionally let them fully

discharge. To do this, simply use the scanner

until it beeps every 15 seconds and flashes.

• To prevent damage to Ni-Cd batteries, never

charge them in an area where the temperature is

above 113°F (40°C) or below 40°F (4°C).

9 The Basics

• If you connect an external power source to the

scanner with ALKALINE/RECHARGEABLE set to

ALKALINE, CHArg appears but the scanner

does NOT charge the batteries. This is because

the scanner's microprocessor unit does not

recognize the switch position when you

incorrectly connect an external power source.

Make sure that you use the correct batteries and

set ALKALINE/RECHARGEABLE to the correct

position when you connect an external power

source.

Important: The EPA certified RBRC

Battery Recycling Seal on the

rechargeable battery indicates

RadioShack is voluntarily

participating in an industry program

to collect and recycle these batteries

a the end of their useful life, when taken out of

service in the United States or Canada. The RBRC

program provides a convenient alternative to

placing used rechargeable batteries 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 rechargeable

battery recycling and disposal bans/restrictions in

your area. RadioShack's involvement in this

program is part of the company's commitment to

preserving our environment and conserving our

natural resources.

The Basics 10

using AC power

You can power the scanner using a 6V, 300 mA AC

adapter and a size B Adaptaplug™ adapter (neither

supplied). Both are available at your local

RadioShack store.

Cautions:

• You must use a Class 2 power source that

supplies 6V DC and delivers at least 300 mA.

Its center tip must be set to positive and its plug

must fit the scanner's DC 6V jack. 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, disconnect the adapter from AC power

before you disconnect it from the scanner.

Follow these steps to use the scanner on AC power.

 Make sure the power is turned off.

 Insert the Adaptaplug into the AC adapter's

cord so it reads TIP +. Then, insert the

Adaptaplug into the scanner's DC 6V jack.

 Plug the AC adapter into a standard AC outlet.
