FEATURES

Your RadioShack Notebook Computer Universal 30W Power

Adapter powers notebook computers and other electronic de-

vices by converting a nominal 12-volt input voltage to a regu-

lated output voltage of from 6 to 21 volts at up to 30 watts of

continuous power.

Caution: This power adapter is intended for mobile use in

automobiles, trucks, boats, on commercial aircraft, or with

12V DC portable power sources and is safe for outdoor use.

Care should be taken not to expose the adapter to rain,

snow, or water as moisture could damage internal compo-

nents.

The compact, lightweight power adapter fits inside most com-

puter carrying cases, and can recharge your computer’s in-

ternal battery. The adapter comes with a deluxe, padded

vinyl case. It is reverse-voltage, over-current, over-tempera-

ture, and short-circuit protected.

Your power adapter’s features include:

User-Adjustable Voltage Settings — you select the specific

output voltage (in one-volt increments) by setting a switch.

The power adapter can be set to deliver any voltage from 6 to

21V DC at up to 30 watts maximum.

273-1825rc.fm Page 3 Tuesday, June 1, 1999 2:05 PM

Interchangeable Adaptaplug®Connectors — three Ra-

dioShack Adaptaplug adapters are included with your power

adapter for connecting it to most notebook computers. Addi-

tional Adaptaplugs are available from RadioShack.

Power Indicators — the power adapter has two indicators.

One is located on the cigarette-lighter plug and lights when

input power is available. The other is located on the power

adapter and stays lit when conditions are normal and turns off

if there is a fault in the circuit.

Cigarette-Lighter Fuse Holder — a glass fuse is located in-

side the cigarette-lighter input connector to protect the adapt-

er and the automobile in the unlikely event of a short circuit.

Regulated Output Voltage — keeps the voltage stable with-

in an input range between 11 and 16 volts. This permits the

power adapter to be attached to a device even when high in-

put “surge” voltages might be present, such as when its bat-

tery is charging. The adapter also ensures that the proper

voltage is always delivered to sensitive electronic compo-

nents.

273-1825rc.fm Page 4 Tuesday, June 1, 1999 2:05 PM

Low Input Voltage Shutdown — a special circuit shuts

down the adapter when the input voltage falls below 10V DC.

This safeguards batteries used to power the adapter that are

susceptible to damage when operated below such voltages.

Input Coil Cord — a special polyurethane material with

“memory” capability enables the cord to stretch up to 5 feet

and return to its original compact size of about 12 inches to

prevent tangling.

SAFETY INSTRUCTIONS

This manual contains important safety and operating instruc-

tions for your power adapter. Before you use the power

adapter, read all the instructions and cautionary markings in

this manual, on the power adapter, and on the product that

you will connect to the power adapter.

Warning: To reduce the risk of injury:

• Do not disassemble the power adapter; take it to your

local RadioShack store when service or repair is

required. Improper reassembly may result in the risk of

fire.

• Do not use an attachment not recommended or sold by

RadioShack or this could result in a risk of fire, injury to

persons, or damage to personal property.

• Never push any object into the air ventilation slots and

openings in the power adapter. It could short out parts

resulting in a fire.

Caution: To reduce the risk of damage:

• Do not expose the power adapter to rain or excessive

moisture.

• Do not operate the power adapter if it has been dam-

aged in any way. Take it to your local RadioShack store

for repair.

273-1825rc.fm Page 7 Tuesday, June 1, 1999 2:05 PM

• Slots and openings on the top and bottom of the power

adapter are for ventilation. To ensure reliable operation,

and to protect the adapter from overheating, be sure

these openings are not blocked or covered.

• Unplug the power adapter from the DC power source

before attempting to adjust voltage, change tips, or clean

it. Do not use liquid aerosol cleaners. Use a damp cloth

for cleaning, then wipe it dry immediately.

• Do not operate the power adapter with damaged input or

output cords or plugs.

• Make sure the cords are not located where they will be

stepped on, tripped over, or otherwise subjected to dam-

age or stress.

• Disconnect the plugs from the socket by pulling directly

on the plugs rather than the cord.

• If your power adapter does not operate normally, in par-

ticular if unusual sounds or smells come from it, immedi-

ately unplug it and contact your local RadioShack store.

PREPARATION

ADJUSTING OUTPUT VOLTAGE

Warning: Your power adapter provides direct current (DC)

voltage. Do not use it with devices that are not specifically

identified as requiring DC voltage. Do not use it with devices

that require AC voltage. Damage to the device could result.

Caution: Make the proper voltage setting before you connect

the power adapter to an input power source.

Follow these steps to adjust the output voltage.

1. Determine the required output voltage setting of the

power adapter by one of the following four methods:

• Refer to “Compatible Notebook Computers” on Page

22 for voltage, tip color, and polarity settings.

• Note the voltage indication marked next to the input

jack on the device to be powered. Example:

Vin =

18V

18V DC

• Review the power or ID plate on the device to be pow-

ered. Look for the word

“INPUT”

followed by a number

and

V DC

. Example:

INPUT: 18V DC

273-1825rc.fm Page 9 Tuesday, June 1, 1999 2:05 PM

• Review the power or ID plate on the AC power

adapter usually used to power the device. Look for the

word

“OUTPUT”

followed by a number and

V DC.

Example:

OUTPUT: 18V DC

If the power adapter or computer indicates a “voltage

range,” use the voltage that is closest to the mid-range.

Example:

OUTPUT: 10–16V DC

; set the power supply to

13V DC.

Note: The specific notation “V DC” might not

be indicated. Instead, the international sym-

bol shown to the right might be used.

In rare cases when the voltage setting is between whole

numbers, such as 15.5V DC, use the lower setting first

(15V DC). If the device does not seem to operate prop-

erly, readjust it to the higher value (16V DC).

2. Remove the protective label covering

the voltage selector. Then, using the

tool provided, or a small flat-blade

screwdriver, turn the adjustment dial

to align its arrow with the required

setting on the label.
