Before Installation
■ Do Not Touch the Lens with Bare Hands
Do not touch the lens with bare hands. Any smudges or
fingerprints on the lens may affect image quality.
■ Allow a 30 Min. Warm Up before Focus Adjustment (P59), if Possible
Immediately after startup, the heat of the light source may prevent stable focus.
When adjusting focus, it is also helpful to use the test pattern (10) (P117, P197).
■ 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.
Similarly, do not install in narrow,
enclosed spaces with poor
ventilation. Install in a well-
ventilated location. Ensure a
minimum clearance of 50 cm (1.6')
above, on both sides, and behind
the projector, as shown below.
Also ensure a minimum clearance
of 2 cm (0.8") below the projector.
■ Be Careful of Condensation
If the temperature of the room rises suddenly, moisture in the air may condense on
the projector lens and mirror, causing the image to become blurred. Wait until the
condensation has evaporated for the image projected to return to normal.
■ At Altitudes above 2,300 m (7,545.8'), Adjust the Settings
Projector settings must be adjusted when using the projector at altitudes of 2,300 m
(7,545.8') or higher. Specifically, refer to instructions for [High altitude] (P112) in the
[Install settings] menu.
