Installation

Installation Precautions
• Place the projector in a well-
ventilated environment.
- To prevent internal overheating, install the projector in a well­ventilated place. Do not place anything near the projector. That may block its air vents. If the air vents are blocked, the internal temperature of the projector will increase.
- Do not place the projector on a carpet or rug. If the projector’s inlet vent is on the bottom, be careful not to block the vent and always use the projector on a solid, level surface.
- Be sure to prevent foreign objects such as paper debris from entering the projector.
ENGLISH
- Leave an adequate open area (30 cm or more) around the projector.
• Do not place the projector in a hot,
cool, or humid environment.
• Do not place the projector in a place
where it will easily attract dust.

22
• The projector is manufactured using
high-precision technology. You may, however, see tiny black dots and/ or bright colored dots (red, blue or
ENGLISH
green) that continuously appear on the projector screen. This is a normal result of the manufacturing process and does not indicate a malfunction.
• 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.
• To install to the ceiling, attach the
ceiling-type bracket to the projector with M4 x 8 mm screws.
