IMPORTANT: Always activate a screen saver program during your application . If a still image in
high contrast remains on the screen for an extended period of time, it may leave a so called "after-

gradually over a period of time after switching off the power. Be aware that the after-image symptom
can not be repaired and is not covered under warranty.
