8.1.1 Automatic Brightness Adaption
Note:
The application of Automatic brightness adaptation allows the user to
configure the respective display brightness.
The display brightness can be changed manually, or alternatively automatically by enabling the
Automatic brightness adaptation, which controls the brightness automatically depending on the ambient
light level. Once the automatic brightness control is enabled, the brightness can no longer be modified
by using the front keys.
We distinguish between two different control modes with the automatic control:
Day mode / Night mode
Separate display brightness levels can be programmed for either of both modes.
Note:
The threshold for Day-/Night mode has to be determined individually by the
user for each device.
The day mode is enabled as soon as the ambient brightness is high enough. The display brightness
should be set to a slightly higher level than at night.
The night mode is enabled if the ambient brightness level is low. The display brightness can be set to a
lower level in this mode.
The operating mode of the automatic control can seamlessly be changed between day and night mode
by using a slide control.
The closer the slider is to the day mode position, the darker the ambient light must be before the display
brightness is changed to night mode. And vice versa: the closer the slider is put to the night mode
position, the brighter the ambient light must be before the display brightness is increased to the value
set up for the day mode.
In order to save the changes, you'll have to push either Save or OK.
