This chapter explains the operating precautions and maintenance for the projector.

Operating Precautions

Pay attention to the following points when using the projector:

•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 in good condition.

•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, remove the projector from the packing case before using. 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. If this happens, move the projector away from the television or radio.

•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.

•Do not use benzene or paint thinners. Doing so may cause the projector to warp, discolor, or the paint to peel. Further, do not use cleaning cloths that contain chemicals.
