equipment. Do not operate the projector on a sofa, rug, or other soft surface, or set it on top of loose
papers. Do not cover the projector with a blanket, curtain, or tablecloth. If you are setting up the
projector near a wall, leave at least 7.9 inches (20 cm) of space between the wall and the projector. Do
not install the projector in an airtight location.
• Do not operate the projector in badly ventilated or narrow places, such as in a closet, AV rack, or book
case.
• Do not operate the projector in a closed-in cabinet or airtight location unless proper ventilation is
provided. If the location is not sufficiently ventilated, hot exhaust from the projector will accumulate
and could trigger the projector's built-in protection circuits, and the projector may malfunction.
• For projectors with air intake vents at the bottom, do not place anything under the projector, such as
cloth or paper. If these are pulled to the air intake vent during projection, the internal temperature
could rise and cause a fire.
• Never allow objects of any kind to enter any openings in the projector. Do not leave objects, especially
flammable objects, near the projector. Do not place any containers of liquid or chemicals on top of the
unit. Never spill liquid of any kind into the projector. Fire or electric shock may result.
• Do not insert or drop metal, flammable, or foreign objects into the projector's vents or openings nor
leave them nearby. Doing so may result in fire, electric shock, or burns.
• If you are using two or more projectors side-by-side, leave at least 43.3 inches (110 cm) of space
between the projectors to allow for proper ventilation.
• You may need to clean the air filter and vent. A clogged air filter or vent can block ventilation needed
to cool the projector. Do not use canned air, or the gases may leave a residue.
• Do not use or store the projector in locations where it will be subject to dust or dirt. Otherwise, the
quality of the projected image may decline, or the air filter may become clogged, resulting in a
malfunction or fire.
• Follow the maintenance schedule for this projector. If the interior of the projector has not been cleaned
for a long time, dust may build up, which could cause the internal temperature of the projector to rise,
resulting in malfunctions, early deterioration of optical parts, and even fire or electric shock. Replace
your air filter periodically and contact your dealer to clean the interior of the projector, as needed.
• Do not store the projector outdoors for an extended length of time.
• Except as specifically explained in this manual, do not attempt to service this product yourself. Refer
all servicing to qualified personnel. Opening or removing covers may expose you to dangerous
voltages and other hazards.
• Never open any covers on the projector except as specifically explained in this manual. Never attempt
to disassemble or modify the projector (including consumables). Refer all repairs to qualified service
