available in the internet at "www.ad.siemens.de" under the heading "Products & Solutions."

Click on "Service & Support" under "Services" and look for the article-ID "16532108" on the

"Product Support" page. The desired article about chemical resistance will be displayed.

Sources of light

Notice

Position the screen so that it is not subject to direct sunlight or other strong sources of light.

Faulty pixels in the display

At present, the manufacturing process of modern displays does not guarantee that all pixels

of the display will be perfect. A small number of faulty pixels in the display, is therefore

unavoidable. This does not present a functional problem as long as the faulty pixels are not

bunched in one location.

For additional information, refer to the technical data.

TFT-LC display

A permanent picture with bright images can lead to a burn-in effect on the LCD.

If a screen saver is activated, please observe the following:

• The liquid crystals in screen savers which actuate active black when the backlighting is

on, e.g. flying stars "starfield simulation," renew themselves. Pay attention to the length of

time the backlighting is activated.

• The following applies to screen savers which turn off the the backlighting tubes: Each

time the backlighting is turned on, its life is reduced by 50 minutes.

Consider the following carefully:

• Use of a screen saver

• Turn off the backlighting regularly

• Permanent display of the customer application
