9. Maintenance • Soak the tissue paper that you used in water, and then throw it away as burnable trash. • When you carry the projector by hand, hold it with both hands and keep it in a horizontal position. If you hold the projector with one hand, its covers may come off or you may drop it. • If moving the projector under conditions including vibration and shock, use both the packing case and included carrying bag. Transporting the projector using the carrying bag only may damage it due to shock or vibration. Further, transporting the projector in a damaged packing case may damage the projector, so use a packing case that is strong enough to protect the projector from shock or vibration. • Do not apply volatile substances such as insecticide to the projector. Also, do not bring the projector into long-term contact with rubber or vinyl products. Doing so may cause discoloration or the paint to peel. • The projector is not intended for long-term continuous operation. Further, do not use the projector before removing it completely from the packing case. If a malfunction occurs when using the projector under these conditions, a fee is charged for repair even if the warranty is still in effect. • Do not use locations that may be hot, such as near a heater. Doing so may cause the projector to malfunction or reduce the service life. • Avoid locations that may become smoky. Particulates may adhere to the optical parts, reducing the service life and causing the image to darken. • Using the projector close to a television or radio may adversely affect the images and sound. • Do not expose the projector to salt air or corrosive gas. Also, do not place the projector in a laboratory or other location where a chemical reaction might occur. Doing so may cause the projector to malfunction. • Moving the projector from a low-temperature location to a high-temperature location may cause water droplets to form on the projector lens and parts due to condensation. Continued use under such conditions may cause malfunction, so do not use the projector until the water droplets have evaporated. • The air is thin at high elevations, so the cooling efficiency of the projector is reduced. Select [On] in [High Altitude Mode] before using. • Do not use the projector in an extremely inclined position (±20° or greater). Doing so may cause malfunction or reduce the service life. • Clean the air filter and the bottom air intake at a regular interval. If the filter becomes clogged, it may cause the inside of the projector to overheat and reduce the service life of the optical parts. • If the air filter is damaged, replace it with a new one. Using a damaged air filter may allow dust or dirt to get inside the projector and cause the projector to stop working or malfunction. 154
