REPLACING THE

BATTERY PACK

If you follow the instructions in “Charg- ing the Battery Pack” on Page 7, the supplied battery pack should last for several years. When the battery pack loses its ability to fully charge, replace the battery pack with a new 3.6 volt, 300 mAh battery pack with a connec- tor that fits the connector pins in the battery compartment. You can order a replacement battery pack through your local RadioShack store.

Follow these steps to install the new battery pack, then charge it for at least 15 hours (see “Charging the Battery Pack” on Page 7).
