Off The projector is in standby or sleep mode. You can unplug it or press the P Power button to turn it on. Cleaning and Replacing the Air Filter Clean the air filter and air 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 brush). 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. Cleaning the Projector Case Before you clean the case, first turn off the projector and unplug the power cord. ❏ To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth. ❏ To remove stubborn dirt or stains, wipe the case with a soft cloth moistened with a mild detergent. Caution: Do not use wax, alcohol, benzene, paint thinner, or other chemical detergents. These can damage the case. If dirt is difficult to remove or the filter is torn, replace it.
