Maintenance

Other care

Inside of the projector
To ensure the safe use of your projector, have it cleaned and inspected by your
dealer every year.
Caring for the lens
If the lens is flawed, soiled or fogged, it could cause deterioration of display
quality. Take care of the lens, being cautious of handling.
1.
Turn the projector off, and unplug the power cord. Allow the projector to cool
sufficiently.
2.
After making sure that the projector is cool adequately, lightly wipe the lens
with a commercially available lens-cleaning wipe. Do not touch the lens
directly with your hand.
• Use commercially available lens tissue to clean the lens (used to clean cameras,
eyeglasses, etc.).
• If the lens is heavily soiled, wipe it with a cloth moistened with little water.
• Never use polishing agents, detergents, chemicals, or solvents such as benzine
or thinner.
• Excepting for lens, use a soft cloth to clean. When excessively soiled, dilute a
neutral detergent in water, wet and wring out the soft cloth.
