Air Filter and Vent Maintenance
The projector's air filter keeps the intake air clean, and its vents expel the exhaust. If dust collects on the
air filter or vents, clean them as described in this manual. Dust clogs may cause the projector to overheat
due to improper ventilation.
Be sure to clean the air filter and vents if you see a message telling you to do so. Also make sure nothing
