Lens and main unit cleaning
WARNING
Request cleaning and maintenance of a ceiling-mounted unit from your
projector dealership.
Attempting to clean the unit or replace the lamp in a high
location by yourself may cause you to fall, possibly resulting in injury.
•
Lens cleaning
Clean the lens with a commercially available blower
and/or lens cleaner.
The lens is easily scratched, so do not rub it with hard
objects, or strike it.
Main unit cleaning
Always unplug the power cord before cleaning the main unit.
Wipe dirt off the main unit gently using a soft cloth.
Do not wipe the main unit with a damp cloth.
Doing so may allow water to get inside, resulting in
possible electric shock or unit failure.
Do not use benzene, thinner or other similar
chemical solutions as they may deform or discolor
the unit or damage the paint surface.
Do not use a chemically saturated cloth.
