IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS!

This manual contains important safety and operation instructions for 

your battery charger. Before using your charger, read all instructions 

and cautionary markings on the charger, the batteries to be charged, 

and the product that uses the batteries.

Warnings:

• Charge only Ni-Cd or Ni-MH batteries with this charger. Other 

types of batteries might burst, causing personal injury.

• Do not try to charge batteries other than those listed in this 

manual, or use procedures other than those described in this 

manual.

• Unplug the AC/DC adapter from AC outlet before attempting 

any maintenance or cleaning.

• Do not disassemble the charger; 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.

• Do not use an attachment not recommended or sold by 

RadioShack as this could result in a risk of fire, electric shock, 

or injury.

Cautions:

• Do not expose the charger to rain or excessive moisture.

• Do not operate the charger if it has been dropped or damaged. 

Take it to a qualified service technician for repair.

• Do not use an extension cord. Its use could result in fire or 

electric shock.

• Never use the charger and the AC/DC adapter as a DC power 

source for any electrical equipment.

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. 

• 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 charger. 

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 interfer-

ence received, including interference that may cause undesired op-

eration.

Your charger is ETL listed to UL standards and meets all applicable

FCC requirements.

OPERATION

Power the charger using the supplied 12V, 700mA AC adapter.

Cautions:

You must use a Class 2 power source that supplies

12V DC and delivers at least 700 mA. Its center tip

must be set to positive and its plug must fit the

charger's 

DC 12V 700MA 

jack. The supplied adapter meets these

specifications. Using an adapter that does not meet these spec-

ifications could damage the charger or the adapter.
