Cleaning the lens
To clean the lens, complete the following procedure:
1.
Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
Note:
Avoid using an excessive amount of cleaner, and do not apply the
cleaner directly to the lens. Abrasive cleaners, solvents or other harsh
chemicals might scratch the lens.
2. Lightly wipe the cleaning cloth over the lens in a circular motion. If you do not
intend to use the projector immediately, replace the lens cap.
Replacing the projection lamp
Use only a replacement lamp with the same type and rating as the original lamp.

Note: Turn off the projector, unplug the power cord, and allow the projector to
cool for at least 1 hour before attempting to replace the lamp.
