These can damage the case. Do not spray cleaner directly on the projector. Cleaning and Replacing the Air Filter Clean the air filter and air intake vents on the bottom of the projector after every 100 hours of use. If not cleaned periodically, they can become clogged with dust, preventing proper ventilation. This can cause overheating and damage the projector. Follow these steps: 1. Turn off the projector, allow it to cool down, and unplug the power cord. 2. Turn the projector upside down. Use a small vacuum cleaner designed for computers and other office equipment. If you don't have one, use a very soft brush (such as an artist's paintbrush). Cleaning the Lens Clean the lens whenever you notice dirt or dust on the surface. ❏ Use a canister of compressed air to remove dust. ❏ To remove dirt or smears on the lens, use lens-cleaning paper. If necessary, moisten a soft cloth with lens cleaner and gently wipe the lens. Caution: Do not use glass cleaner to clean the lens and do not spray liquid of any kind directly on the lens. Spray the cleaner on a soft cloth and then gently wipe the lens with the cloth. If dirt is difficult to remove or the filter is torn, replace it.
