Never run the projector with the filter removed. It is recommended that the air filter is cleaned regularly. (A recommended measure is about once for every 50 hours of use.)

Notes • Allowing dirt and dust to build up on the air filter will worsen the air circulation inside the projector, causing the internal temperature to rise, causing the projector to stop working or malfunction. • Insert the air filter cover all the way in. Leaving gaps will allow dust and dirt to get inside the projector. • If you wash the air filer with water, make sure to dry it completely before replacing it. • If the air filter is torn, consult with your dealer about replacing it with a new one. Continuing to use a ripped filter will allow dust and dirt to get inside the projector. 57 Maintenance
