Before maintenance

f When switching off the projector, make sure to follow the procedures in “Switching off the projector”
(x page 68).
Maintenance
Outer case
Wipe off dirt and dust with a soft, dry cloth.
f If the dirt is persistent, soak the cloth with water and wring it thoroughly before wiping. Dry off the projector with
a dry cloth.
f Do not use benzene, thinner, or rubbing alcohol, other solvents, or household cleaners. Doing so may
deteriorate the outer case.
f When using chemically treated dust cloths, follow the instructions written on its packaging.
Lens front surface
Wipe off dirt and dust from the front surface of the lens with a soft clean cloth.
f Do not use a cloth that is uffy, dusty, or soaked with oil/water.
f Since the lens is fragile, do not use excessive force when wiping the lens.
Attention
f The lens is made of glass. Impacts or excessive force when wiping may scratch its surface. Handle with care.
Note
f Dust may accumulate around the air intake port depending on the environment or usage conditions such as when using the projector in a
dusty place. If the projector is used in such environment, the circulation of ventilation, cooling, and heat exhaust may weaken, causing the
luminance to dimmer.
