ALC (optional)
Ambient Light Compensation (ALC) is an optional system that
automatically adapts the display contrast and brightness level to the
ambient light in the room. The system has to be adjusted by setting
the contrast and brightness in the darkest ambient light conditions the
user works, and then repeating this in the brightest conditions.
To adjust the ALC system, proceed as follows:
1. Dim the light in the room to create the darkest ambient light
condition the user normally works in.
2. Enter the Minimum illuminance menu.
3. Select Measure ambient light. The display now stores the
ambient light level that corresponds to the darkest condition.
4. Select Contrast and set the display contrast to the desired level.
5. Select Brightness and set the display brightness to the desired
level.
6. Exit the Minimum illuminance menu.
7. Increase the light in the room to create the brightest ambient light
condition the user normally works in.
8. Enter the Maximum illuminance menu.
9. Select Measure ambient light. The display now stores the
ambient light level that corresponds to the brightest condition.
10. Select Contrast and set the display contrast to the desired level.
11. Select Brightness and set the display brightness to the desired
level.
12. Exit the Maximum illuminance menu.
