Maintenance
Periodic maintenance will keep your DP9100 in top working condition.
CLEANING THE LENS AND MIRROR
To clean the projection lens and mirror:
1 Take a piece of lens tissue and form it into a loose swab. Wet it with lens
cleaning fluid or denatured alcohol, and gently wipe it over the surface of
the lens or mirror.
2 Take another clean piece of lens tissue and repeat the process, wiping it
over the lens or mirror in the opposite direction.
Repeat this process until no smudges or particles can be seen. DO NOT
LOOK DIRECTLY INTO THE LENS WHEN THE LAMP IS ON!
Caution: Do not use acetone to clean the lens. It may remove paint from
areas around the lens or mirror and leave a residue on the glass.
CLEANING THE PROJECTION WINDOW
The projection window is the surface through which the LCD image is
projected. To maintain 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 of the LCD panel inside the
projector. Point the can into the opening in the top center of the right
side of the projector (see Figure 5-1).
