							9. Maintenance
This chapter explains the operating precautions and maintenance for the projector.
Operating Precautions
• The machine's light uses a mercury vapor lamp that becomes high pressure when it is turned on. The lamp has the following characteristics, so be sure to handle it with care after understandingthe contents. If the lamp explodes and either you are injured from broken pieces of glass, think
you have gotten glass particles or mercury vapour in your eyes, or have inhaled glass particles
or mercury vapour, contact a doctor immediately.
• Deterioration or shock can cause the lamp's life span to end or the lamp to explode. If the lamp explodes, it may make a big noise.
• The time that it takes for the lamp to reach its life span or explode depends on each individual lamp and its operating conditions. It is possible that it might explode the first
time it is used.
• If you use the lamp past its replacement period, the possibility of explosion increases.
• If the lamp explodes, broken glass pieces may be scattered around the inside of the machine and ejected from the vent or other opening.
• If the lamp explodes, a very small amount of mercury vapor in the lamp tube and broken glass pieces may be ejected from the vents or other opening.
Pay attention to the following points when using the projector:
• What to do if a lamp has exploded • If the lamp explodes, remove the power cord from the projector, leave the room while makingsure it is thoroughly ventilated.
• If the lamp explodes and you think that you have gotten glass particles or mercury vapor in your eyes or have inhaled either, contact a doctor immediately.
• Clean up the area around the projector completely while being careful not to get injured from any broken glass pieces.
• Throw away any food that was near the projector. • Ask your service representative to replace the lamp and inspect the projector.
• What to do if a battery has leaked • If leakage from a battery adheres to your skin, rinse it with water immediately, and thencontact a doctor.
• Wipe off the leakage with tissue paper while being careful not to touch it.
147   
						

							• 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 regularly. 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.9. Maintenance
