Display settings (P820)

The backlight on the display of the phone 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 devices. 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.
