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.
Disclaimer
• ViewSonic® does not recommend the use of any ammonia or alcohol-based
cleaners on the display screen or case. Some chemical cleaners have been
reported to damage the screen and/or case of the device.
• ViewSonic® will not be liable for damage resulting from use of any ammonia or
alcohol-based cleaners.
NOTE: If condensation appears between the glass and the panel, keep the
display turned on until the moisture disappears.
