Battery Function
The telephone displays a battery charge indicator icon in the idle screen to indicate the battery
charge level. The gauge shows four levels: 100%, 66%, 33%, and Low Battery.
Removing the battery causes the phone to shut down immediately and loose any pending work
(partially entered phone book entries or outgoing messages, for example).
Note: All batteries can cause property damage and/or bodily injury such as burns if a
conductive material such as jewelry, keys, or beaded chains touches exposed terminals. The
conductive material may complete an electrical circuit (short circuit) and become quite hot.
Exercise care in handling any charged battery, particularly when placing it inside a pocket,
purse, or other container with metal objects.
If the battery is removed while receiving a message, the message is lost.
To ensure proper memory retention, turn the phone OFF before removing the battery.
Immediately replace the old battery with a fresh battery.
Operation
For detailed operating instructions, refer to the appropriate User Guide listed in the Related
