Display settings
Backlight and contrast on the display of the phone and on the displays of any connected expansion
modules 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 vertical 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. The phone setting is applied to all D3 extension
modules connected to the phone, as well.
