Focus adjustment
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.
When using the Zoom Lens (Model No.: ET-D3LEW200) or the Fixed-focus Lens (Model No.: ET-D3LEU100), it is
recommended to perform the focus adjustment after at least an hour has elapsed with an image displayed.
When using a projection lens other than the Zoom Lens (Model No.: ET-D3LEW200) or the Fixed-focus Lens
(Model No.: ET-D3LEU100), it is recommended to perform the focus adjustment after at least 30 minutes have
elapsed with the focus test pattern displayed. For details of the test pattern, refer to “[TEST PATTERN] menu”

r
Do not install the projector at an altitude of 4 200 m (13 780') or higher above sea level.
r
Do not use the projector in a location that the ambient temperature exceeds 50 °C
(122 °F).
Using the projector in a location that the altitude is too high or the ambient temperature is too high may reduce the
life of the components or result in malfunctions.
Upper limit of the operating environment temperature varies depending on the altitude above sea level.
When using the projector at an altitude between 0 m (0') and 1 400 m (4 593') above sea level: 0 °C (32 °F) to
50 °C (122 °F)
When using the projector at an altitude between 1 400 m (4 593') and 4 200 m (13 780') above sea level: 0 °C
(32 °F) to 45 °C (113 °F)

Cautions when setting up the projector
f
Install the projector in a place or with a mount that can sufficiently tolerate the weight. The position of the
projected image may shift if the strength is not sufficient.
f
Use the adjustable feet only for the floor standing installation and for adjusting the angle. Using them for other
purposes may damage the projector.
f
The adjustable feet can be removed if not needed in the installation. However, do not use the screw holes
where the adjustable feet were removed to fix the projector to a mount.
Also, do not attach any screws not instructed in the operating instructions of the optional accessories into the
screw holes where the adjustable feet are removed. Doing so may damage the projector.
f
When using the projector in any method other than the floor installation using the adjustable feet or ceiling
mounting installation using the Ceiling Mount Bracket, remove the four adjustable feet and use the six screw
holes (as shown in the figure) to fix the projector to a mount.
