Clean
the projection window periodically, or whenever you notice dust or
smudges on the surface.
Warning:
Before cleaning the projection window, turn off the projector and
unplug the power cord.
To remove dust or smudges, gently wipe the
projection window with clean and dry
lens-cleaning paper.
Caution:
Do not wipe the projection window right
after you turn off the projector or you may damage it.
If the projection window
is dusty, blow off the dust and then wipe the projection
window.
Warning: Do
not use any flammable gas sprays such as air dusters to blow off
dust. The high heat generated by the projector may cause a
fire.
Caution:
Do not use canned air, or the gases may
leave a flammable residue. Do not use glass cleaner or any harsh
materials to clean the projection window and do not subject the
projection window to any impacts or you may damage it.
