Your RadioShack 13.8 VDC 15-Amp Regulated

Power Supply is designed to power equipment

that requires 12V DC automotive power. The power

supply converts standard 120V AC household

power to 13.8V DC power and can supply up to 15

amps of continuous power.

Press POWER to turn on the power supply. If POWER

does not light:

• Check your connections and conﬁrm the AC

outlet has power.

• If the outlet has power, turn off the power

supply and reduce the load (use a device that

requires 13.8V DC or less). Press POWER.

Your power supply’s overload protection circuit

automatically shuts down the power supply when

it becomes overloaded. It resets when you turn off

the power supply.

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.

• Connect the equipment into an outlet on a circuit different from that

to which the receiver is connected.

• 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 power supply. Changes or modiﬁcations not expressly

approved by RadioShack may cause interference and void the user’s

authority to operate the 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.

Read Instructions — Safety and operating instructions should be read prior to

use.

Retain Instructions — The safety and operating instructions should be retained

for future reference.

Heed Warnings — Follow all warnings on the appliance and in the instructions.

Cleaning — Unplug this appliance from the wall outlet before cleaning. Use a

damp cloth for cleaning. Do not use liquid or aerosol cleaners.

Water and Moisture — Do not use this appliance near water (for example, near

a bathtub, washbowl, kitchen sink, or laundry tub; in a wet basement; or near a

swimming pool).

Mounting Accessories — Do not place appliance on an unstable cart, stand,

tripod, bracket, or table. The appliance may fall, causing injury to a child or

adult, and damage the appliance. Use only with a cart, stand, tripod, bracket,

or table recommended by the manufacturer or sold with the appliance. Follow

the manufacturer’s mounting instructions, and use a recommended mounting

accessory.

Ventilation — Slots and openings in the cabinet provide ventilation, ensure

reliable operation, and protect from overheating. Do not block or cover these

openings, and do not place the appliance on a bed, sofa, rug, or other similar

surface. Do not place the appliance in a built-in installation such as a bookcase

or rack unless it provides proper ventilation as speciﬁed by the manufacturer.

Heat — The appliance should be situated away from heat sources such as

radiators, heat registers, stoves, or other appliances that produce heat.

Power Sources — Use this appliance with the power source indicated on its

marking label. If you are not sure of your home’s power type, consult your

appliance dealer or local power company.

Grounding or Polarization — This appliance is equipped with a three-wire

grounding-type plug, a plug having a third (grounding) pin. This plug will only ﬁt

into a grounding-type power outlet. This is a safety feature. If you are unable to

insert the plug into the outlet, contact your electrician to replace your obsolete

outlet. Do not defeat the safety purpose of the grounding-type plug.

Power-Cord Protection — Route power-supply cords so they are not likely to

be walked on or pinched by items placed on or against them, paying particular

attention to cords at plugs, convenience receptacles, and the point where they

exit from the appliance.

Cleaning — The appliance should be cleaned only as recommended by the

manufacturer. Clean by wiping with a cloth slightly dampened with water. Avoid

getting water inside the appliance.

Power Lines — An outside antenna system should not be located in the vicinity

of overhead power lines or other electric light or power circuits, or where it can

fall into such power lines or circuits. When installing an outside antenna system,

extreme care should be taken to keep from touching power lines or circuits, as

contact with them might be fatal.

Nonuse Periods — The appliance’s power cord should be unplugged from the

outlet when it is to be left unused for a long period of time.

Overloading — Do not overload wall outlets, extension cords, or integral

convenience receptacles. This can result in ﬁre or electric shock.

Objects and Liquids — Never spill liquids or push objects of any kind into this

appliance through openings, as they may touch dangerous voltage points or

short out parts that could result in a ﬁre or electric shock.

Carts and Stands — If the appliance is used with a cart or stand, the cart or

stand should be a type recommended by the manufacturer. An appliance and

cart combination should be moved with care. Quick stops, excessive force, and

uneven surfaces cause the appliance and cart combination to overturn.

Damage Requiring Service — Refer servicing to qualiﬁed service personnel

under these conditions:

* When the power-supply cord or plug is damaged.

* Liquid was spilled or objects fell in the appliance.

* If the appliance has been exposed to rain or water.

* If the appliance does not operate normally by following the operating

instructions. Adjust only those controls that are covered by the operating

instructions, as an improper adjustment of other controls may result in

damage and will often require extensive work by a qualiﬁed technician to

restore the appliance to normal operation.

* If the appliance has been dropped or damaged.

* When there a distinct change in performance.

Servicing — Do not attempt to service this appliance yourself, as opening or

removing covers may expose you to dangerous voltage or other hazards. Refer

all servicing to qualiﬁed service personnel.

Replacement Parts — When replacement parts are needed, use only parts

speciﬁed by the manufacturer or parts with the same characteristics as the

original part. Substitutions may result in ﬁre or electric shock.

Safety Check — Upon completion of service or repairs, ask the service

technician to perform safety checks to determine if the appliance is in operating

condition.

Lightning — For added protection during a lightning storm, or when the

appliance is unused for long periods of time, unplug it from the wall outlet. This

prevents damage due to lightning and power surges.

Attachments — Do not use attachments not recommended by the product

manufacturer as they may cause hazards.

Wall or Ceiling Mounting — The product should be mounted to a wall or ceiling

only as recommended by the manufacturer.
