    							7. 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.
    143   
    						
    							• 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 tilted to either side (20° or greater). Doing so may cause malfunction or reduce the service life.7. Maintenance
    144  
    						
    							Cleaning the Projector• Do not remove any covers or screws that are not mentioned in this manual. There are highvoltage components inside the machine that may cause electric shock. Contact your servicerepresentative if any of the machine's internal components require maintenance, adjustment, or
    repair.
    • Do not disassemble or modify the machine. Doing so may cause injury or malfunction.
    • Do not attempt to clean or replace parts for a machine that is installed in a high location on a wall or ceiling. Doing so may cause it to fall down, resulting in an injury.
    • Do not open the lamp cover of a machine that is installed on a wall or ceiling. Doing so may cause the lamp cover to fall down. If the lamp is broken, pieces of glass may fall and cause an
    injury.
    • Contact your sales or service representative to clean or replace parts for a machine that is installed on a wall or ceiling.• When performing maintenance on the machine, always disconnect the power cord from thewall outlet.
    Cleaning the Lens
    When cleaning the lens, make sure to do the following:
    • Use a commercially available blower or cloth for cleaning glass, cleaning paper, plastic lens cleaner, etc.
    • The lens surface scratches easily, so do not rub or tap it with a hard object.
    Cleaning the Projector
    When cleaning the projector, make sure to do the following: • Disconnect the power plug before cleaning.
    • Gently wipe any dirt from the projector using a soft cloth. Using a damp cloth may cause water to seep inside the projector and cause electric shock or malfunction.
    • 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.

    							Replacing the Lamp• Before replacing the lamp, turn off the power and wait at least one hour to allow the machine tocool completely. If it is not completely cool, you may burn or injure yourself due to the inside of
    the machine and lamp unit being hot. If you replace the lamp without unplugging the power cord
    from the power outlet, electric shock or explosion may occur.
    • Be careful when handling the used lamp so that it does not break. If it breaks, it may cause injury. • Do not attempt to clean or replace parts for a machine that is installed in a high location on a wall or ceiling. Doing so may cause it to fall down, resulting in an injury.
    • Do not open the lamp cover of a machine that is installed on a wall or ceiling. Doing so may cause the lamp cover to fall down. If the lamp is broken, pieces of glass may fall and cause aninjury.
    • Contact your sales or service representative to clean or replace parts for a machine that I installed on a wall or ceiling.• Be sure to always use a dedicated replacement lamp that is new when replacing the lamp. If youuse a lamp that is not dedicated, it may result in an explosion and injury.
    • 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 you are either 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.7. Maintenance
    146    
    						
    							• The lamp is a glass product. Do not touch the glass surface with bare hands, hit it forcefully, ordamage it. For details about what to do if a lamp has exploded, see page 143 "Operating
    Precautions".
    • This projector's lamp contains trace amounts of environmentally harmful inorganic mercury. Be careful not to break used lamps, and dispose of them in accordance with local regulations or
    contact your sales representative or service representative.
    When the lamp is due for replacement, the message "The lamp is reaching the end of its life. Please
    change it." is displayed. Change the lamp as instructed.
    When [Lamp Power] in [Energy Saving Settings] is specified as [Maximum], replace the lamp after approximately 3,500 hours. When the setting is [Low], replace it after approximately 5,000 hours.
    However, depending on the characteristics of the lamp and how the lamp is used, the image may
    become dim or the lamp may go out before the message is displayed. We recommend preparing a
    spare lamp, just in case.
    Do not repeatedly turn off the projector immediately after the lamp is lit, or turn on the projector
    immediately after turning it off. Doing so may damage the lamp or shorten its life.
    Furthermore, if the lamp is used for an extended period of time, the image may darken or the lamp may
    burn out. If this happens, replace the lamp with a new one.
    You need a Phillips screwdriver to replace the lamp.
    1. Slide the outer lamp cover to the right to remove it.
