Key Functions
● Power Button lets you turn the device on or off, or turn the screen backlight on or off. This
button can be configured to end a call.
● LED Indicator shows your device’s battery status. It also flashes for incoming calls or
pending notifications.
● Proximity Sensor/Light Sensor automatically deactivates the touchscreen when you hold
the device near your face. This prevents you from unintentionally activating device functions
during a call. It also automatically turns off the backlight and brightens the display when you
are in sunlight or a bright room, and dims the display in darker places.
● Volume Button allows you to adjust the ringtone and media volumes when you are not on a
call, or the voice volume during a call.
