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.

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.
