Cautions when transporting
f
When transporting the projector, move the lens position to the home position and attach the lens cushion.
If lens optional model, move the lens position to the home position, remove the projection lens, and then attach
the lens hole cover.

Do not set up the projector in the following locations.
f
The projector is designed for indoor use only.
f
Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal
components or malfunction.
components or malfunction.
f
Location close to sea or where corrosive gas may occur: The projector may fall due to corrosion.
Also, it may shorten the life of the components and result in malfunctions.
Also, it may shorten the life of the components and result in malfunctions.
f
Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may fluctuate in rare cases
due to the heated air from the air exhaust port or the hot or cooled air. Make sure that the exhaust from the projector
or other equipment, or the air from the air conditioner does not blow toward the front of the projector.
due to the heated air from the air exhaust port or the hot or cooled air. Make sure that the exhaust from the projector
or other equipment, or the air from the air conditioner does not blow toward the front of the projector.
f
Places with sharp temperature fluctuations such as near lights (studio lamps): Doing so may shorten the life
of the lamp, or result in deformation of the outer case due to heat, which may cause malfunctions.
The operating environment temperature of the projector should be between 0 °C (32 °F) and 45 °C (113 °F) when
using it at elevations lower than 1 400 m (4 593') above sea level, and between 0 °C (32 °F) and 40 °C (104 °F) when
using it at high altitudes (between 1 400 m (4 593') and 2 700 m (8 858') above sea level).

f
Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
f
Places where there is high-power laser equipment: Directing a laser beam onto the lens surface causes damage
to the DLP chips.

f
Do not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
■
Note at the time of installation
f
The high clarity projection lens is thermally affected by the light from the light source, making the focus unstable in
the period just after switching on the power. It is recommended that images be projected continuously for at least
30 minutes before the focus is adjusted.

f
Do not use the projector tilted to the right or left.
Using the projector at a vertical angle that exceeds ±15° may reduce product life or result in malfunction.
