Cautions when transporting

・

When transporting the projector, hold it securely by its bottom and avoid excessive vibration and impacts. 
They may damage the internal components and result in malfunctions.

・

Do not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.

■

 

Do not set up the projector in the following locations

・

The projector is designed for indoor use only.

・

Places where vibration and impacts occur such as in a car or vehicle : Doing so may cause damage to internal
components or malfunction.

・

Near the exhaust of an air conditioner : Depending on the conditions of use, the screen may fluctuate in rare cases
due to the hot air from the air exhaust port or the heated 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.

・

Places with sharp temperature fluctuations such as near lights (studio lamps) : Doing so may result in deformation
of the projector body 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 (1 400 m (4 593') – 2 700 m (8 858') above sea level).

・

Near high-voltage power lines or near motors : Doing so may interfere with the operation of the projector.

・

Place where there is high-power laser equipment : Directing a laser beam onto the lens surface causes 
damage to the DLP chips.

Note at the time of installation

・

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. Wait at least 30 minutes with the image projected before adjusting
the focus.

・

Make sure to set [HIGH ALTITUDE MODE] to [ON] when using the projector at elevations between 1 400 m (4 593')
and 2 700 m (8 858') above sea level.
Make sure to set [HIGH ALTITUDE MODE] to [OFF] when using the projector at elevations lower than 1 400 m
(4 593') above sea level.

・

Do not install the projector at elevations of 2 700 m (8 858') or higher above sea level.

・

When installing and using the projector at an angle that exceeds 30° vertically, set [COOLING CONDITION].

・

Do not use the projector with the connecting terminal side up.

・

For the portrait setting, set the projector directly facing the screen.
If the projector is vertically installed in the portrait setting, the keystone correction for the vertical tilt is not available.
In this case, the keystone correction works for the horizontal tilt.
