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 (P46),
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) (P105, P152).
■ 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. 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] (P147) in the
[Install settings] menu.
