Low Battery Alert

When the battery pack is very low, the phone is programmed to eliminate functions in order to save power. When LOW BATTERY appears in the display and the phone is in standby, none of the keys will operate. If you are on a call, complete your conversation as quickly as possible, and return the handset to the charging cradle.

The battery pack needs to be charged when the empty battery icon appears.

Low Battery

Talk and Standby Times

With average use, your handset battery provides approximately 5 hours of talk time and approximately 7 days of standby time. When your handsets are not being used and are left off of their charging cradles, the battery will gradually discharge. You can achieve optimum battery life and performance by returning the handset to the charging cradle after each use. If the handset is left off of the charging cradle, the actual talk time duration will be reduced respective to the amount of time the handset is off of the charging cradle.
