Installation and Maintenance Installation
■ Do Not Use in the Following Environments
• Do not install the projector in a location that is damp, or where there is a lot of
dust, oily smoke or tobacco smoke. Optical parts such as the lens and mirror may
be stained, resulting in poor picture quality.
• Do not install the projector near high-voltage electrical power lines or an electrical
power source. The projector may not operate correctly.
• Do not use the projector on a soft surface such as carpet or sponge mat, etc.
Heat may accumulate inside the projector, causing a malfunction.
• Do not use the projector in a location that is subject to very high temperatures,
very low temperatures, or high levels of humidity. Doing so may cause a
malfunction. The temperature and humidity ranges for operation and the
temperature range for storage are shown below.
■ Do Not Touch the Lens with Bare Hands
Do not touch the lens with bare hands. Doing so may adversely affect picture
quality.
■ Allow a 30 Min. Warm Up before Focus Adjustment (P59), if Possible
The focus position may not stabilize immediately after startup, due to lamp heat.
When adjusting focus, it is also helpful to use the test pattern (10) (P291).
■ Install at a Sufficient Distance from Walls and Other Obstructions

If the air intake or exhaust vent
is blocked, heat will accumulate
inside the projector, possibly
resulting in a shortened
projector lifetime or a
malfunction. Do not install in a
closet, on a bookshelf, or in
other narrow spaces with poor
ventilation. Install in a well-
ventilated location. (Ensure a
minimum clearance of 50 cm (1.6 ft.) above, on both sides, and
behind the projector.)
