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.
