Cleaning and Replacing the Air Filter
An air filter is installed in the air intake vent on the bottom of the main body to protect the
internal lens and mirror from dust. Should the air filter become clogged with dust, the pro-
jector may be damaged since it will block the air flow into the projector and raises the
internal temperature of the projector. The following screen is displayed when turning on
the projector if the air filter needs to be cleaned. Clean the air filter if such is the case.
■Cleaning the Air Filter
• Turn the projector upside down, remove the cover by pushing the latch, remove the air
filter, and clean it with a vacuum cleaner.
• When cleaning dust off the rear exhaust vent and bottom air intake vent, bring the vac-
uum cleaner nozzle close to them directly.
• If the above screen is displayed when turning on the projector after cleaning the air fil-
ter, select [Yes].
