Cleaning the Projector
Clean the projector frequently to prevent dust from settling on the surface.
A dirty lens may ruin the quality of the projected image.
Wipe the projector’s main unit softly with a soft cloth.
If the projector is heavily soiled, soak the cloth in water with a small amount of detergent
in it, squeeze the cloth thoroughly, and then wipe the projector with it. After cleaning, wipe
the projector with a dry cloth.
When cleaning the projector, make sure to turn off the projector,
wait until the cooling fan stops, disconnect the power plug from the
AC outlet, and let the projector stand for at least 1 hour. Otherwise,
you may get burned because the main unit is very hot immediately
after the projector is turned off.
• Never use volatile cleaning liquid or benzine, as these may damage the finish of the pro-
jector.
• When using a chemical dust cloth, make sure to read the instructions thoroughly.
• When cleaning the projector’s lens, use a commonly available air blower or lens cleaning
paper. The lens surface is easily damaged, so do not use a hard cloth or tissues.
