6. Cleaning a Soiled Projector Main Unit.
(1). Wipe with a lint-free, soft, dry cloth. When very dirty, wipe with a cloth that has been moistened with
a diluted neutral detergent, then finish with a dry cloth. If a chemically-treated cloth is going to be used,
please follow any written warnings.
(2). Do not wipe with thinner, benzene, or other solvents. Doing so could cause them to undergo
qualitative changes or the coatings may peel, etc.
(3).When removing the dust of the outflow and intake holes, use the brush attachment on a vacuum
cleaner to clean out thedust. Avoid using the vacuum directly without attaching the adapter as well as
the use of a nozzle adapter.
(4).Do not scratch or otherwise hit the projector body with your nails or other hard object, since this will
cause scratches.
7. Dust of the Intake and Outflow Holes
Dust that collects in the intake and outflow holes will obstruct the ventilation and cause the internal
temperature to rise which could cause damage. Clean this area carefully. As a guideline, clean at least
every 100 hours of usage.
a.
Turn off the power and check that the indicator of the POWER/STANDBY has changed so that it is lit
in orange, and then disconnect the power cable.
b.
Vacuum from the outside with an electric vacuum cleaner. Use a brush-tipped adapter with the
vacuum cleaner. Note that use of a vacuum without an adapter, or use of an adapter without a brush
should be avoided.
8. Cleaning the Inside of the Projector
Cleaning of the inside of the projector is required about once a year. Failure to clean over a
long period while dust has collected inside the projector could cause a fire or breakdown. Do
not clean the inside of the projector by yourself. Please be sure to contact your dealer.
