Adjusting the Brightness of the Display
The brightness of the displays is regulated automatically by
the ECOS, depending on the ambient brightness. You can
set a minimum degree of brightness manually, which is
always observed when the brightness is regulated.
1. If necessary, open the main menu (Esc) and press the
F4 button (1) (Figure 3-49) once. The Settings submenu
opens (Figure 3-50).
2. Press the F3 button (1) once (Figure 3-50).
A red bar will appear below the percent display.
3. Set the required minimum degree of brightness with the
adjustment knob (2).
The brightness of the display changes during the setting
procedure and you can view the set value (0 to 100%)
on the display. The degree of brightness which you set
here is the minimum value for the automatic regulation.
NOTE: There is no automatic regulation if you set 100%.
The displays are always displayed with maximum
brightness.
You can cancel the input at any time by pressing the Esc
button. The settings are then reset.
4. To accept the entered minimum brightness, press the
Enter button.
The red bar below the display goes out. The brightness is
automatically regulated between the newly set value and
100%.
