REPLACING THE

BATTERY PACK

If you follow the instructions in “Con- necting and Charging the Battery Pack” on Page 10, the battery pack should last about one year. If the bat- tery pack does not hold a charge for more than 2 hours after an overnight charge, replace the battery with a new 3.6-volt, 600 mAH battery with a con- nector that fits the socket in the battery compartment. You can order a re- placement battery pack through your local RadioShack store.

Install the new battery pack as de- scribed below, then charge it for about

14hours (see “Connecting and Charg- ing the Battery Pack” on Page 10).

Note: To avoid losing phone numbers stored in memory, try to install and be- gin charging the new battery pack with- in 3 minutes.

1.Loosen the screw on the battery compartment cover on the bottom of the handset, and slide off the cover in the direction of the arrow.

2.Lift the battery pack out of the compartment, then gently pull on the battery connector to discon- nect it.

3.Insert the new battery pack’s con- nector into the socket in the com- partment and place the battery pack into the compartment.

4.Replace the cover, then reinsert and tighten the screw.

Cautions:

•You must use a replacement bat- tery pack of the same size and type.

•Do not dispose of the battery pack in a fire because it might explode.

•Do not open or mutilate the battery pack.

•Be careful not to short the battery pack by touching the connector’s pins with conducting materials, such as rings, bracelets, and keys. The battery pack or conduc- tor might overheat and burn.

If you have trouble replacing the bat- tery pack, take the phone to your local RadioShack store for assistance.

Important: This product contains a re- chargeable nickel-cadmium battery pack. At the end of the battery pack’s useful life, it must be recycled or dis- posed of properly. Contact your local, county, or state hazardous waste man- agement authorities for information on recycling or disposal programs in your area. Some options that might be available are: municipal curb-side col- lection, drop-off boxes at retailers such as your local RadioShack store, recy- cling collection centers, and mail-back programs.
