Cleaning and Maintenance
Cleaning the Screen
Do not use substances such as glass cleaners, solvents, and thinners.
The screen of your RPTV has been specially treated. Wipe the surface
gently using only a cleaning cloth or a soft, lint-free cloth.
If the surface is particular dirty, use a soft cloth and water to clean the screen.
Squirt a little water on the cloth (never directly on the screen), then wipe the
screen with the cloth.
Warning The screen of your RPTV is made of specially coated plastic
and can be scratched or damaged by abrasive or
ammonia-based window cleaners. Scratches on the bezel or
screen are not covered by your warranty.
Do not scratch or hit the surface of the screen with your fingers or any hard
objects.
Cleaning the Exterior
Your Micro Chip Display Projection TV is cooled by air circulated through the
vents on the case, so keep the vents free of dust. With your Micro Chip
Display Projection TV turned off and unplugged, brush the dust away from
the vents with a damp cloth. Be careful not to drip any water into the vents.
Do not attempt to clean dust from the inside of your Micro Chip Display
Projection TV.
Do not use abrasive or solvent cleaners because they can damage the finish
on components.
Do not allow any excessive water or moisture to come into contact with the
surface of your Micro Chip Display Projection TV. If water or moisture gets
inside your Micro Chip Display Projection TV, operating problems and
electrical and shock hazards may result.
Do not scratch or hit the cabinet with your fingers or any hard objects.
Do not place articles made from rubber or PVC near the cabinet for any
extended periods of time.
