 Ensure that the intake vents do not recycle hot air from the exhaust vent.
 When operating the projector in an enclosed space, ensure that the surrounding air temperature
within the enclosure does not exceed operation temperature while the projector is running, and the
air intake and exhaust vents are unobstructed.
 All enclosures should pass a certified thermal evaluation to ensure that the projector does not
recycle exhaust air, as this may cause the device to shutdown even if the enclosure temperature is
with the acceptable operation temperature range.
