Before Installation 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 Air intake vent 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. Warmed airflow Exhaust vent Ensure a minimum clearance of 50 cm (1.6') Air intake vent 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.
