FEATURES

Your RadioShack 12-Volt • 10-Amp Regulated Power Supply is de­signed to power equipment that requires 12V DC au tomotive pow­er. The power supply converts standard 120V AC household power
to 13.8V DC power and can supply up to 10 amps of continuous
power.

Your vehicle’s 12-volt electrical system provides 13. 8 Volts

Note:

when the engine is running.
If you are an electronic h obbyist or t echnician, y ou will appr eciate

the many uses for the power supply at your workbench or in your
house. For example, use your CB mobile transceiver as a base
station, check the operation of autosound syst ems before you in­stall them in your vehicle, or even power marine equipment such
as pumps.

Your power supply’s features include:

This manual contains im portant safety and operating instructions

for this power supply. Before you use the power supply, read all the
instructions and cautionary markings in this manual, on the power
supply, and on the produ ct that you will connec t to the powe r sup­ply.

Warnin

can result in fire or electric shock.

ing an improper extension cord could result in a risk of fire and
electric shock. If an extension cord must be used, make sure:

a. The pins on the extension cord’s plug are of the same num-

ber, size, and shape as those of the plug on the power sup­ply.

b. The extension cord i s properly wired and in goo d electrical

condition.

c. The extension cord’s wire size is at least 18 AWG.

• Do not disassemble the power supply; take it to a qualified ser­vice technician when service or repair is required. Improper re­assembly may result in a risk of electric shock or fire.

22-506.fm Page 5 Friday, August 6, 1999 12:55 PM

• Do not use an attachment not recommended or sold by Ra-

dioShack or this could result in a risk of fire, electric shock , or
injury to persons.

• Never push any object into the slot in the power supply. It could

touch dangerous voltage points or short out pa rts resulting in a
fire or electrical shock.

Caution

: To reduce the risk of damage:

• Do not expose the power supply to rain or excessive moisture.

• Do not operate the power supply if it has been dropped or

damaged in any way. Take it to a qualified service technician
for repair.

• Slots an d openings on the back and bottom of the po wer sup-

ply’s cabinet are for ventilation. To ensure the power supply’s
reliable operation and to protect it from overheating, be sure
these openings are not blocked or covered.

• The power supply should be operated only from a standard AC

outlet that provides 120V AC/60 Hz, as indicated on the label.
If you are not sure of t he ty pe of powe r s upplied t o y our h ome ,
consult your local power company.

• For added safety, the power supply’s polarized plug (one blade

wider than the other) fits only into a polarized outlet. If your AC
outlet is not designed for the polarized plug, have an electrician
install the correct outlet, or use an adapter to ground the power
supply safely. Do not defeat the safety purpose of the plug.

• To protect the power sup ply during a lightning storm or wh en it

is left unattended and unused for long periods of time, unplug it
from the AC outlet. This will prevent damage to the power sup­ply from lightning and power surges.

• Unplug the po wer s upply f rom the o utl et before a ttem pting any

maintenance or cleaning. Do not use liquid or aerosol cleaners.
Use a damp cloth for cleaning and then wipe it dry immediately .

• Do not operate the power supply with a dam aged cord or plug
— replace them immediately. To reduce the risk of dama ge to
the electric plug and cord:

a. Make sure the cord is not located where it will be stepped

on, tripped over, or otherwise subjected to damage or stress.

b. Disconnect the power supply by pulling the cord’s plug

rather than the cord.

• If your power supply does not operate normally, in particular if
any unusual sounds or smells com e from it, immediately un­plug it and contact your local RadioShack store.
