9 CLEANING AND MAINTENANCE
The Projector and DigiOptic™ Image Processor do not require
internal cleaning. There are no user serviceable parts inside
the projector. Please refer all service requirements to qualified
personnel.
Cleaning the projector’s cover:
Use a soft slightly damp cloth. Do not use abrasive cleaners,
solvents or other harsh chemicals, as this will damage the finish
of the cover. Avoid direct cleaning of the rear panel’s screen-
printing.
Cleaning the lens:
The lens may be cleaned with a very soft, non-abrasive small
brush, in order to remove dust particles. Alternatively, use a
soft dry cleaning cloth (of the type used for camera lens
cleaning) to remove fingerprints and grease marks.
