3. When charging is finished, unplug the adapter from the 

power outlet and disconnect it from the phone by 
pressing the buttons on both sides of the connector (1) 
and pulling the connector out (2). 

Note: You must unplug the adapter before you remove the battery from the 
phone during charging; otherwise, the phone could be damaged.

When the battery is weak and only a few minutes of talk 
time remain, a warning tone sounds and the “Warning 
Low Battery” message repeats at regular intervals on the 
display. When this happens, your phone turns off the 
backlight to conserve the remaining battery power. 

When the battery level becomes too low, the phone 
automatically turns off.
