Do’s and Don’ts
Do:
• Operate the projector in a well-ventilated room to avoid a
buildup of ozone from the projector’s high-performance lamp.

• Use a dampened soft cloth to clean the display housing.
• Disconnect the power plug from AC outlet if the projector is not
being used for a long period of time.To disconnect the cord, pull
it out by the plug. Do not pull on the cord.
• Use lint-free gloves or finger cots when changing the lamp.
Never touch a lamp with your bare hands. The invisible residue
from the natural oil on your hands may shorten the lamp life.
Don’t:
• Place the projector on an unstable cart, stand, or table. If the
projector falls, it may be seriously damaged.
• Operate the projector near paper, cloth, or other combustible
material, or in proximity to inflammable substances, such as
paint thinner. Never operate the projector if covered with
combustible materials. The projector gets hot and combustible
and inflammable materials may catch fire.
• Use abrasive cleaners, waxes or solvents to clean the
projector.
• Use under the following conditions:
— In extremely hot, cold or humid environment.

— Near any appliance generating a strong magnetic field.
— In direct sunlight.
— Near any heat source, such as radiators, heat registers,
stoves, or other products (including amplifiers) that produce
heat.
— In a smoky area. Smoke residue may cause buildup on
critical parts, including the lens.

the coverings of the internal components may damage them
and void your warranty.
