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 an 'after-
image' or 'ghost image' on the front of the screen. This is a well-known phenomenon that is
caused by the shortcomings inherent in the LCD technology. In most cases the after-image
will disappear gradually over a period of time after the power has been switched off. Be
aware that the after-image symptom cannot be repaired and is not covered under warranty.
