Display backlight and contrast settings
Backlight and contrast can be adjusted separately for the times when the phone is active and when the phone is
idle. Lowering backlight intensity lowers the energy consumption of the device. The backlight when idle can be
reduced to zero bars.
NOTE:
When the phone has been inactive for a specified number of seconds it will switch the
backlight to idle mode. This setting is available only on the phone's web user interface, not on
the phone itself.
