Removing and replacing handset battery pack
After years of use, all NiMH rechargeable batteries loose the ability to hold
a full charge and may need to be replaced. The handset uses 1 NiMH 650
mAh 3.6V (AAA) rechargeable battery pack. Only replace with an approved
ID-2820 battery pack available through AT&T. Contact the AT&T Customer
Service Center at 800-667-2118 to order.
WARNING: There is a risk of explosion if the battery pack is replaced with
an incorrect battery pack type. Dispose of the used battery pack according
to your local waste management guidelines.
To install a replacement handset battery pack:
1. Remove the battery door cover on the telephone handset.
2. Insert the battery pack as shown.
3. Slide the cover back on so that it clicks firmly into place.
NOTE: Before using the handset and to prolong battery life, place the
handset in the base handset cradle and charge for at least 15 hours.
