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:

1Use 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).

Blowing air into the projector

2Take 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.

3Take another clean piece of lens tissue and repeat the process, wiping it over the projection window in the oppo- site direction.

4Repeat if necessary.

Caution: Do not use lens cleaning fluid to clean the projec- tion window. It may damage the surface.
