Maintenance and cleaning

Maintain the cleanliness of all internal components during any service procedure. All of the projector
optics must remain free of contaminants to perform at the level specified. Even a small amount of dust
or a fingerprint may degrade the image or cause a noticeable reduction of brightness.
Always power down and disconnect/disengage all power sources to the projector before servicing or
cleaning the lens or before any of the projection head covers or doors are loosened and removed. If
the seal is broken while the intake fans are still operating, internal components are immediately
vulnerable to contamination from inbound particles.
Notice. If not avoided, the following could result in property damage.
• Avoid touching optical elements.
• Always wear clean, lint-free gloves when handling the product.
