Level III Service Manual General Operation
Battery Function
Battery Charge Indicator
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.
Battery Removal
Removing the battery causes the device to immediately shut down and any pending
work (partially entered phone book entries or outgoing messages, for example) is
lost.
Operation
For detailed operating instructions, refer to the appropriate User Guide listed in
the Related Publications section toward the end of this manual.
E
All batteries can cause property damage and/or bodily injury such as burns if a
conductive material such as jewelry, keys, or beaded chains touch 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.
G
If the battery is removed while receiving a message, the message will be lost.
➧
To ensure proper memory retention, turn the phone OFF before removing the
battery. Immediately replace the old battery with a fresh battery.
