cloth that contains a small amount of non-

blower to clean the lens.

Abrasive cleaners, solvents, or other harsh
chemicals might scratch the surface of the
lens.
Unplug the AC power cord before cleaning.

and finish with a soft dry cleaning cloth.
Avoid using an excessive amount of cleaner.

chemicals might scratch the surface of the

When the projector is not in use, put the

protect it from dust and scratches.
When moving this projector or while not using
it over an extended period of time, attach the
lens cap.

to secure it in place.
To pass the other end of the string into the
hole on the bottom of the projector and
pull at it.
Do not use any flammable solvents or air
sprays on the projector and in its vicinity.
The explosion or fire hazard may occur
even after the AC power cord is unplugged
because the temperature inside the projector
is extremely high due to the lamps. In
addition, there is a risk that the internal parts
may be damaged not only by the flammable
air spray but also by the cold air.
