to the heated air from the air exhaust port or the hot or cooled air. Make sure that the exhaust from the projector or other
equipment, or the air from the air conditioner does not blow toward the front of the projector.
fPlaces with sharp temperature uctuations such as near lights (studio lamps): Doing so may shorten the life of the lamp, or
result in deformation of the outer case due to heat, which may cause malfunctions.
The operating environment temperature of the projector should be between 5 °C (41 °F) and 40 °C (104 °F) when using it
at elevations lower than 1 400 m (4 593') above sea level, and between 5 °C (41 °F) and 35 °C (95 °F) when using it at high
altitudes (between 1 400 m (4 593') and 2 700 m (8 858') above sea level).
fNear high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
rBe sure to ask a specialized technician when installing the product to a ceiling.

rCautions when setting the projectors
fDo not stack the projectors.
fDo not use the projector supporting it by the top.
fDo not block the ventilation ports (intake and exhaust) of the projector.
fAvoid heating and cooling air from the air conditioning system directly blow to the ventilation ports (intake and exhaust) of
the projector.
fDo not install the projector in a conned space.
When placing the projector in a conned space, a ventilation and/or air conditioning system is required. Exhaust heat may
accumulate when the ventilation is not enough, triggering the protection circuit of the projector.

Cautions on use
rTo get a good picture quality
fDraw curtains or blinds over windows and turn off any lights near the screen to prevent outside light or light from indoor
lamps from shining onto the screen.
fDepending on where the projector is used, heated air from an exhaust port or warm or cold air from an air conditioner can
cause a shimmering effect on screen.
Avoid use in locations where exhaust or streams of air from projector, other devices and air conditioners ow between the
projector and the screen.
fThe lens of projector is affected by the heat from the luminous source. Because of this, the focusing may not be stable right
after the power is turned on. Focusing is stabled after projecting image for 30 minutes and longer.
rDo not touch the surface of the projector lens with your bare hand.
If the surface of the lens becomes dirty from ngerprints or anything else, this will be magnied and projected onto the screen.
rLCD Panel
The display unit of this projector comprises three LCD panels. Although an LCD panel is a product of high-precision
technology, some of the pixels on the projected image may be missing or constantly lit. Please note that this is not a
malfunction.
Displaying a still image for a longer time may result in an after-image on the LCD panels. If this happens, display the all white
screen in the Test pattern for an hour or more.
rOptical components
Operating the projector in an environment with high temperature or heavy exposure to dust or tobacco smoke will reduce the
service life of the optical components, such as the LCD panel and polarizing plate, and may necessitate their replacement
within less than one year of use. For details, consult your dealer.
rLamp
The luminous source of the projector is a mercury lamp with high internal pressure.
A high pressure mercury lamp has following characteristics.
fThe brightness of the lamp will decrease by duration of usage.
fThe lamp may burst with sound or shorten life by shock or chipping.
fThe life of the lamp varies greatly depending on individual specicities and usage conditions. In particular, continuous use
over 6 hours and frequent on/off switching of the power greatly deteriorate the lamp and affect the lamp life.
fIn rare cases, the lamp burst shortly after the projection.
fThe risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit
consistently. (“When to replace the lamp unit” (x page 88), "Replacing the lamp unit" (xpage 89))
fIf the lamp bursts, gas contained inside of the lamp is released in a form of smoke.
fIt is recommended to store replacement lamps for contingency.
rComputer and external device connections
fWhen connecting a computer or an external device, read this manual carefully regarding the use of power cords and
shielded cables as well.
