							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 understanding
the 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 making
sure 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.
153   
						

							• 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.

							Cleaning the Projector
• Do not remove any covers or screws that are not mentioned in this manual. There are high
voltage components inside the machine that may cause electric shock. Contact your service
representative 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 the
wall outlet. Cleaning the Air Filter
• An error in which the lamp turns off by itself during operation may occur if the air filter and the
bottom air intake vent get clogged and the interior of the projector overheats due to inadequate
circulation of air. Clean the air filter and the bottom air intake vent also when "Temperature Error" is
displayed.
• If an air filter is damaged, replace it with a new one. Using a damaged air filter may cause the
projector to stop operating or malfunction. For details, contact your sales representative or service
representative.
The air filter prevents dust and dirt from entering the interior of the projector. If you will use the projector,
install the air filter.
If the message "Check the air filter for dirt." is displayed, check the air filter for dirt or dust, and use the
following procedure to clean off any dirt or dust.
1. Disconnect the power plug. Cleaning the Projector

							2.
Gently slide and pull out the bottom air intake vent cover to remove it, and then use a
vacuum cleaner to clean any dirt or dust from the intake vent. 3.
Install the bottom air intake vent cover by sliding it gently back into place.
Check that the bottom air intake vent cover is correctly installed. • The message is displayed only once at the following occasions:
•Every 500 hours
•
After the machine restarts when an error that the lamp turns off by itself during operation has
occurred
• The message is displayed for 30 seconds after the machine has been turned on. The message disappears when you perform any operation.
• Depending on the environment in which the projector is located, the filter may get clogged earlier than expected. When any dust or dirt has visibly collected on the air filter, clean it regardless of
whether the warning message is displayed or not. A buildup of dust on the air filter may cause poor
ventilation, causing the interior of the projector overheat and operations to stop or malfunction.
• If vacuuming the air filter does not remove the dust and dirt, wash it with water. After washing the air filter with water, make sure to dry it completely before reinstalling it back in
the projector.
Cleaning the Projection Window When cleaning the projection window, make sure to do the following:
• Use a commercially available blower or cloth for cleaning glass, cleaning paper, lens cleaner, etc.
•
