ᕡ Handling and Care of Mirror Surface
If the projector is not to be used for an extended period of time, close the mirror cover.
This will protect the projector against dropping an object or gathering dust.
Consult with your dealer when using the projector exposed to smoke or dust.
Long-term exposure to sulfide can corrode the mirror surface.
If the mirror surface is soiled with fingers prints or dust, wipe them
off with the supplied cleaning cloth.
When removing sandy dust, use a blower to blow off dust or brush
it off softly and wipe the mirror surface with the supplied cleaning
cloth.
Cleaning the mirror face
Keep finger prints off the mirror surface. Do not scratch the
mirror surface with a hard or pointed object.
Leaving a defect in the mirror surface might cause an unwanted
shadow and poor picture quality.

• Do not blow your breath against the mirror surface, which can accidentally put your saliva on the mirror
surface.
Leaving foreign grease stains, oil-smudged finger prints or salt on the mirror surface can cause damage to
the reflective coating on the mirror surface.
Use only the supplied cleaning cloth to clean the mirror surface. Failure to do so can mar the mirror
surface.
• Do not force the cleaning cloth against the mirror surface or apply excessively strong pressure against it.
Do not scratch it with your nails while wiping off.
• Never use strong detergents or solvents such as thinner or benzene. Doing so can corrode the reflective
coating on the mirror surface.
If heavily soiled and wiping with the cleaning cloth will not work, use absolute alcohol. After the mirror
surface is dried, wipe it with the cleaning cloth again.
• If the supplied cleaning cloth is soiled, wash it. It is recommended you wash it every after two to three uses.
Do not allow long-term close contact with rubber or vinyl products because this could cause the reflective
coating of the mirror surface to deteriorate.
• Do not spray volatile substances such as insect repellent on the mirror surface.
