Attention
f To ensure projector performance and security, installation of the Ceiling Mount Bracket must be carried out by your dealer or a qualied
technician.
Projected image and throw distance
Install the projector referring to the projected image size, projection distance, etc.
When the Zoom Lens (Model No.: ET-D3LEW200), the Fixed-focus Lens (Model No.: ET-D3LEU100,
ET-D75LE95), or the Fisheye Lens (Model No.: ET-D3LEF70) is used, the projection relation between the screen
and the projector differs from that of other lenses.
For details, refer to “ET-D3LEU100, ET-D3LEW200” (x page 45), “ET-D75LE95” (x page 46), or
“ET-D3LEF70” (x page 47).
Attention
f Before setting up, read “Precautions for use” (x page 21).
f When the Fixed-focus Lens (Model No.: ET-D75LE95) is used, install the projector so that its back plane is parallel to the screen, making
the projected image rectangular.
The vertical keystone distortion in moderate range can be corrected with the [POSITION] menu → [GEOMETRY] → [KEYSTONE] →
[VERTICAL KEYSTONE] (x page 120) even after the projector is installed. For the range that can be corrected, refer to “[GEOMETRY]
projection range” (x page 49).
f Do not use the projector and the high-powered laser equipment in the same room. The DLP chips can be damaged if a laser beam hits the
projection lens surface.
