■
Do Not Touch the Lens with Bare Hands
■
Allow a 30 Min. Warm Up before Focus Adjustment (
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) (
).
■
Install at a Sufficient Distance from Walls and Other Obstructions
■
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] (
) in the
[Install settings] menu.
Do not touch the lens with bare hands. Doing so may adversely
affect picture quality.
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 ft.) above, on both sides, and
behind the projector, as shown below.
