rechargeable battery. To charge the battery, follow
these steps:
1. Connect the cable from the power supply to the
outlet in the phone.
2. Connect the power supply to an AC wall outlet as

If the phone is turned off, the screen displays the
message, “Battery Charging.” When the battery
is charged, “Charging Complete” displays.
If the phone is turned on, the battery indicator
bar blinks and displays the current power level.
When the battery is charged, the indicator bar
stops blinking.
3. When the battery is fully charged, disconnect the
charger from the phone, and unplug the power
cord from the AC wall outlet.
