supply. Before using the projector, check that the power supply to which the
projector is to be connected meets these requirements.
• Usea poweroutlet astheprojector’spowersupply.Donot connect the
projector directly to electrical light wiring. Doing so is dangerous.
• Wheninstallingtheprojectoratanangle,theseparatelysoldoptioncover

• 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.

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.

Important Information
xix
- Do not let water or other liquids get on the remote control. Should the remote control get wet,
wipe it off immediately.
- Avoid using in hot and humid places as far as possible.
- When planning not to use the remote control for long periods of time, remove both batteries.
• Takemeasurestopreventexternallightfromshiningonthescreen.
Make sure only the light from the projector shines on the screen. The less external light on the
screen, the higher the contrast and the more beautiful the images.
• Aboutscreens
Images will not be clear if there is dirt, scratches, discoloration, etc. on your screen. Handle the
screen with care, protecting it from volatile substances, scratches and dirt.
