Important!:
The battery charging function may stop if you are on a call or
viewing a streaming-video while charging your battery.
Note:
During charging, you must unplug the adapter before removing the
battery from the phone to avoid damage.
Low Battery Indicator
When the battery is weak and only a few minutes of talk time
remain, a warning tone sounds, the “Battery Low” message
repeats at regular intervals on the display, and the empty battery
icon ( ) blinks. The backlight turns off to conserve the
remaining battery power.
Note:
If your phone is in Silent Mode, the Low Battery Indicator defaults to
Vibration (see ”Sound Profile” on page 133). If you change the alert
from Vibration to Mute, you will see a flashing message that indicates
a low battery.
If the battery level becomes too low, the phone automatically
turns off. Recharge your battery.
