Preface
Lighting
Proper lighting and comfortable display viewing angle can reduce eye strain and muscle fatigue in your neck and
shoulders.
• Position the display to avoid glare or reflections from overhead lighting or outside sources of light.
• Keep the display screen clean and set the brightness and contrast to levels that allow you to see the screen clearly.
• Position the display directly in front of you at a comfortable viewing distance.
• Adjust the display-viewing angle to find the best position.
LCD Screen Care
To prevent image persistence on LCD monitors (caused by the continuous display of graphics on the screen for
an extended period of time) take the following precautions:
• Set the Windows Power Plans to turn the screen off after a few minutes of screen idle time.
• Use a rotating, moving or blank screen saver (this prevents an image from being displayed too long).
• Rotate desktop background images every few days.
• Turn the monitor off when the system is not in use.

Carrying the Computer
We strongly recommend using both hands to move the computer (one hand gripping the handle area and the other grip-
ping the computer) to avoid accidentally dropping it. Be careful that objects such as belt buckles etc. do not scratch the
screen while it is being carried.
