Precautions for Installation
Installing the Projector
Please read the following properly when installing the projector.
Installation Environment
Please do not install or use this projector in the follow-
ing places as it is a precision device. This could cause
fire or a malfunction.
Where there is water, humidity or dust.
Where the projector may be subjected to oil, smoke or
cigarette smoke.
On a soft surface such as a carpet or cushion
Where the projector may be subjected to direct sunlight.
Where temperature is high or low.
Allowable operation temperature range : +5˚C to +35˚C
Allowable relative humidity range : 20% to 80%
(no condensa-
tion)
Allowable storage temperature range : –10˚C to +60˚C
•Any room in which there is smoke and grease.
Even where smoke and grease level is minimal, prolonged
exposure would affect the projector. The projector emits
heat and cools the optical components down by taking in
large amount of air. When the optical path is soiled by
grease/dirt, images become dark and color projection de-
teriorates, such often being the cause of damage. Re-
moving grease/dirt totally from the optical parts is not pos-
sible.
Precaution for Usage
This projector uses a light-source lamp which becomes
high in temperature when projecting.
Please DO NOT use it in the following ways as it may
result in fire or malfunction.
•Lay the projector on its side when projecting.
Project outside the specified angle.
Do not use the projector while it is set more than ±5˚
horizontally (left/right), or more than ±25˚ vertically (up/
down). This could cause color variation or shorten the
lamp life.
Block the exhaust vents.

Adjusting the Inclination of the Projector
The vertical angle and leveling of the projector can be adjusted with the adjustable feet at the bottom of the projector.
Do not use a cover which may enclose the projector
air-tight or block the exhaust vents. Allow sufficient
space around the projector. When the projector is en-
closed in a space of the following dimensions, use an
air conditioner so that internal and external tempera-
tures are the same.
Adjusting the vertical angle of the projector
While pushing the lever upward, raise the projec-
tor. The maximum extension is approximately
31mm. To retract the foot, push the lever and lower
the projector slowly; the projector is fixed at the
position where you release the lever.
Adjusting the level of the projector
Lift the projector, rotate the front adjustable foot,
and adjust the horizontal angle until the projector
is level.
