To clean the projector lens
■
To minimize the risk of damaging or scratching the lens surface, blow dust
particles off the lens with clean, dry, deionized air.
If this method does not work, use the following method:
■
Wipe the lens in a single direction with a clean, dry cloth. Do not wipe back and
forth across the lens.
If the cloth is dirty or smears the lens, wash the cloth. If the cloth is still dirty after
washing it or the fabric is damaged, replace it.
