Accessory Interface connector and the other end into a 
standard AC wall outlet.

interface connector jack on the phone.
Warning!: If your handset has a touch screen display, please note that a 
touch screen responds best to a light touch from the pad of your 
finger. Using excessive force or a metallic object when pressing on 
the touch screen may damage the tempered glass surface and 
void the warranty. For more information, refer to “Standard 
Limited Warranty”  on page 184.
Note: Failure to unplug the wall charger before you remove the battery, can cause damage to the phone.
Low Batter y Indicator
When the battery is weak and only a few minutes of talk time 
remain, the battery icon ( ) blinks and the device sounds a 
warning tone at regular intervals. In this condition, your phone 
conserves its remaining battery power, not by turning off the 
backlight, but by entering the dimming mode. For a quick check 
of your battery level, glance at the battery charge indicator 
located in the upper-right corner of your device’s display. Solid 
color ( ) indicates a full charge.
