Backlight Function
The backlight provides the background illumination for the LCD display. As
its service life is limited, only 50% of its original brightness will remain after
approx. 15,000 operating hours.
Refer to section 8.2.2 for information about replacing the backlight unit.
To extend the service life of both display and backlight tube, the flat screen
display features a timer (”sleep”) function for the backlight .
This function “darkens” the display when no keyboard or mouse action has
occurred on the CPS21 for a defined period of time. The length of the defined
interval can be selected in the PC BIOS and in the Windows Control Panel.
Pressing a key or moving the mouse again activates the backlight, making
the display visible once more.
Enabling the ”Backlight Off” function
D
In the BIOS setup program, go to the ”Power Management Setup” menu
option. Select the ”OnBoard LCD Backlight Timer OFF” submenu, and
select a time interval between 28 seconds and 14 minutes.
D
Install a screen saver such as ”Blank Screen” that will switch the display
to a ”black signal” in the operating system. Select the ”Wait” period after
which the screen saver will be activated. The interval selected here is ad-
ded to the ”Backlight Timer OFF” interval that was selected in the BIOS.
