Installation Precautions
y
Place the projector in a well-ventilated
environment.
- To prevent internal heat build-up,
install the projector in a well-
ventilated place.
Do not place anything near the
projector as this may block its air
vents. If the air vents are blocked,
the internal temperature will
increase.
- Do not place the projector on a
carpet or rug. If the vent is on the
bottom, use the projector on a solid
level surface and ensure the vent is
not blocked.
- Be sure to prevent foreign objects
such as paper debris from entering
the projector.
- Leave enough distance (30 cm [11.8
inches] or more) around the projector.
y
Do not place the projector in a hot,
cool, or humid environment.
y
Do not place the projector in a place
where it will easily attract dust.
- This may result in fire.
y
Never open any cover on the
projector. There is a high risk of
electric shock.
y
The projector is manufactured using
high-precision technology. You may,
however, see tiny black dots and/
or bright colored dots (red, blue or
green) that continuously appear on
the projector screen. This is a normal
result of the manufacturing process
and does not indicate a malfunction.
y
The remote control may not work
in an environment where a lamp
equipped with electronic ballasts or
a three-wavelength fluorescent lamp
is installed. Replace the lamp with an
international standard lamp for the
remote control to work normally.
