User Maintenance
Periodically clean the projector exterior, lens, intake vents, and exhaust vents on a regular basis.
z Always make sure that the projector has cooled sufficiently before cleaning it. If the
projector is turned on, perform the following steps before cleaning it.
1. Turn off the projector.
2. Check to make sure that the POWER/STANDBY indicator has changed to amber.
3. Unplug the power cord from the power outlet, and allow the projector to cool down for
about 60 minutes.
Cleaning the Projector Exterior
Wipe the exterior of the projector with a soft cloth that has been moistened in a weak solution
of water and a mild neutral detergent. Be sure to wring all excess moisture from the cloth
before wiping.
Never use benzene, alcohol, thinner, or any other volatile agent for cleaning.
Cleaning the Lens
Carefully wipe the lens with a commercially available lens cloth or optical lens paper, like those
for eyeglasses or camera lenses. When cleaning the lens, be very careful to avoid scratching it.
Cleaning Intake and Exhaust Vents
Dust and dirt tend to collect around the intake vents located on the back and both sides of the
projector. Because of this, you should use a vacuum cleaner to clean away accumulated dust
and dirt periodically as shown below.
z Continued use of the projector after dust has accumulated around the intake vents can
cause overheating of internal components and lead to malfunction.
z Certain operating conditions also can cause dirt and dust to accumulate around the
projector’s exhaust vents on the front. If this happens, use the same procedure as that
described above to clean the exhaust vents.
