Backlight Switch-Off

DOK-SUPPL*-BTV16/40***-PR02-EN-P
The backlight as background lighting of the display has a limited lifetime
(see section "Wear Parts" on page 4-8).
To extend the service life of the LCD backlight, the flat screen display
features a backlight switch-off. This function "darkens" the display, if no
operation of the operator terminal has occurred for a certain period of
time. The length of the time interval can be specified in the BIOS settings
and in the Windows Control Panel.
How to activate the backlight switch-off:
• Select in the BIOS setup program menu item "Power Management
Setup" and then submenu item "OnBoard LCD Backlight Timer OFF"
and choose as time interval between "28 sec and 14 min".
• Install a screen saver in the operating system, that will switch the
display to a "black signal" (blank screen, i.e. no objects visible on the
screen). Thereby, select the time interval, after which the screen saver
might be activated. The selected time is added to the "Backlight Timer
OFF" time set in the BIOS.
Note: Ensure that the set interval for the screen saver activation is
shorter than the time for the activation of the backlight switch-
off. If this is not the case, problems to reactivate the display
might occur.
If the display is "darkened" and does not react to a keyboard
input or mouse movement, generally, the backlight can be
reactivated by pressing the key combination "CTRL" + "Tab".
