• Ensure that the air intake vents do not recycle hot air from the exhaust vent.
• When operating in an enclosed space, make sure that the surrounding air temperature does
not exceed the projector's operating temperature and that the air intake and exhaust vents are
unobstructed.
All enclosures should pass a certied thermal evaluation to ensure that the projector does not
recycle exhaust air. Recycling exhaust air may cause the projector to shutdown even if the ambient
temperature is within the acceptable operating temperature range.

Note:
• For more visualized instructions, please go to BenQ calculator website http://projectorcalculator.benq.com/.
• Ceiling installation must be done by a qualied professional. Contact your dealer for more information. It is not
recommended you install the projector yourself.
• Only use the projector on a solid, level surface. Serious injury and damage can occur if the projector is dropped.
• Do not use the projector in an environment where extreme temperature occurs. The projector must be used
at temperatures between 41 degrees Fahrenheit (5 degrees Celsius) and 104 degrees Fahrenheit (40 degrees
Celsius).
• Screen damage will occur if the projector is exposed to moisture, dust or smoke.
• Do not cover the vents on the projector. Proper ventilation is required to dissipate heat. Damage to the
projector will occur if the vents are covered.
