Maintenance
General Precautions
•
Make sure the device is turned off and the power cable is unplugged from the
power outlet.
•
Never spray or pour any liquid directly onto the screen or case.
•
Handle the device with care, as a darker-colored device, if scuffed, may show
marks more clearly than a lighter-colored device.
•
Do not use the system continuously for long periods of time.
Cleaning the Screen
•
Wipe the screen with a clean, soft, lint-free cloth. This removes dust and other
particles.
•
If the screen is still not clean, apply a small amount of non-ammonia, non-
alcohol based glass cleaner onto a clean, soft, lint-free cloth; then wipe the
screen.
Cleaning the Case
•
Use a soft, dry cloth.
•
If the case is still not clean, apply a small amount of non-ammonia, non-alcohol
based, mild non-abrasive detergent onto a clean, soft, lint-free cloth, then wipe
the surface.

ViewSonic® does not recommend the use of any ammonia or alcohol-based
cleaners on the display screen or case. Some chemical cleaners have been
