standard (see Section 6.1 "Picture adjustment"). Normally auto adjust will

work.

4.4 Adjusting the brightness and contrast

The brightness and contrast must be adjusted for the respective graphics card

(different output levels) in the system on site.

Note on adjustment

− Use the SMPTE test pattern.

− Adjust the brightness so that image sections with 5% and 0% blackness still

visibly contrast from one another.

− Adjust the contrast so that image sections with 95% and 100% whiteness

still visibly contrast from one another. To adapt the luminosity to the ambient

lighting, adjust the backlight brightness (note: 500 cd/m² factory setting is

then modified).

4.5 Screen saver

A screen saver function should be used in order to reduce "image sticking"

which can occur in TFT displays. It is high risk to display a static graphic

over half an hour. Image sticking is the effect where a faint image of the

previous screen contents can still be seen after the display contents have

changed. By using a screen saver with permanently changing screen contents,

unnecessary effects of the same image are avoided.

If the keyboard is locked, contact the servicing department in order to unlock

it. The guarantee is cancelled if you unlock it yourself!
