Maintenance and Cleaning
Cleaning the Projector Cabinet
Cleaning the Projection Lens
Unplug the AC power cord before cleaning.
Gently wipe the projection lens with a cleaning cloth that
contains a small amount of non-abrasive camera lens cleaner,
or use a lens cleaning paper or commercially available air
blower to clean the lens.
Avoid using an excessive amount of cleaner. Abrasive
cleaners, solvents, or other harsh chemicals might scratch
the surface of the lens.
