5.1
Cleaning the Projector
• Unplug the power cord before cleaning the
projector.
• Avoid using benzene or thinner, as these can
damage the finish on the projector exterior.
• Do not use volatile agents, such as
insecticides, on the projector.
• Do not leave rubber or plastic objects in
contact with the projector for long periods as
they may damage the finish of the projector.
• Wipe off dirt gently with a soft flannel cloth.
• For hard-to-remove dirt, soak a cloth in a
neutral detergent diluted with water, wring the
cloth well and then wipe the projector.
• Strong cleaning detergents may discolor,
warp or damage the coating on the projector.
Make sure to test on a small, inconspicuous
area on the projector before using.
5.2
Cleaning the Lens
• Use a commercially available blower or lens
cleaning paper (for glasses and camera
lenses) for cleaning the lens. Do not use any
liquid cleaning agents, as they may wear the
coating film on the surface of the lens.
• The surface of the lens is easily damaged. Do
not scrape or hit the lens.
