Cleaning the projection window
The projection window is the surface through which the
LCD image is projected. To ensure that the projector main-
tains a clear, sharp image, you should clean the projection
window from time to time.
To clean the surface of the projection window:
1 Use a can of compressed air to blow dust off the LCD panel
inside the projector. Point the can into the opening in the
top center of the right side of the projector (see the illustra-
tion below).

2 Take a piece of lens tissue and form it into a loose swab.
Wet it with a solution of approximately ten percent Iso-
propyl alcohol and water, and gently wipe it over the sur-
face of the projection window.
3 Take another clean piece of lens tissue and repeat the
process, wiping it over the projection window in the oppo-
site direction.
4 Repeat if necessary.
Caution: Do not use lens cleaning fluid to clean the projec-
tion window. It may damage the surface.
