9 CLEANING AND MAINTENANCE
The projector does 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.
