Cautions for ensuring the projector's performance
• Do not install in places subject to vibrations or shocks.
If installed in places where the vibrations from power sources and the like are conveyed, or in
vehicles or on vessels, etc. the projector could be affected by vibrations or shocks that may dam-
age internal parts and lead to malfunction.
Install in a place not subject to vibrations or shocks.
• Do not install near high voltage power lines or power sources.
The projector may be affected by interference if it is installed near a high voltage power line or
a power source.
• Do not install or store in such places as those described below. Doing so could lead to malfunc-
tion.
- Places where strong magnetic fields are generated
- Places where corrosive gases are generated
• If intense light like laser beams enters from the lens, it could lead to malfunction.
• Consult your dealer before using in places where much cigarette smoke or dust is present.
• Select [HIGH] in [FAN MODE] if you continue to use the projector for consecutive days.
• When the same still image is projected for a long period of time with a computer, etc. the pattern
of the image may remain on the screen after the projection is stopped, but it will disappear after
a while. This happens due to the properties of liquid crystal panels, and is not a malfunction. We
recommend using a screensaver on the computer side.
• When using the projector at altitudes of about 5500 feet/1700 meters or higher, be sure to set
the [FAN MODE] to [HIGH ALTITUDE]. If not, the inside of the projector may get hot, leading to
malfunction.
• When the projector is used at high altitudes (places where the atmospheric pressure is low), it
may be necessary to replace the optical parts sooner than usual.
• About moving the projector
- Remove the lens unit once, and be sure to attach the lens cap so as not to scratch the lens. Also,
attach a dust protective cap to the projector.
- Do not subject the projector to vibrations or strong shocks.
The projector could be damaged otherwise.
• Do not use the tilt feet for purposes other than adjusting the projector's tilt.
Improper handling, such as carrying the projector by the tilt feet or using it leaned against a wall,
could lead to malfunction.
• Do not touch the surface of the projection lens with bare hands.
Fingerprints or dirt on the surface of the projection lens will be enlarged and projected on the
screen. Do not touch the surface of the projection lens.
• Do not unplug the power cord from the projector or the power outlet while projecting. Doing so
could cause deterioration of the projector's AC IN terminal or power plug contact. To interrupt
the AC power supply while images are being projected, use a power strip switch, a breaker, etc.
• About handling of the remote control
- The remote control will not work if the projector's remote signal sensor or the remote control's
signal transmitter is exposed to strong light or if there are obstacles between them that obstruct
the signals.
- Operate the remote control from within 20 meters from the projector, pointing it at the projec-
tor's remote signal sensor.
- Do not drop the remote control or handle it improperly.
