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 projection lens surface
causes damage to the DLP chips.
rAsk a qualified technician or your dealer for the installation work such as installing to
a ceiling, etc.
To ensure projector performance and security, ask a qualified technician or your dealer when installing the
projector in a method other than the floor installation or when installing the projector in a high place.
rAsk a qualified technician or your dealer to install the cable wiring for DIGITAL LINK
connection.
Image and sound may be disrupted if cable transmission characteristics cannot be obtained due to inadequate
installation.
rThe projector may not work properly due to strong radio wave from the broadcast
station or the radio.
If there is any facility or equipment which outputs strong radio waves near the installation location, install the
projector at a location sufficiently far from the source of the radio waves. Or, wrap the LAN cable connected to the
<DIGITAL LINK> terminal using a piece of metal foil or a metal pipe which is grounded at both ends.
rFocus 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-D3LEW200C) or the Fixed-focus Lens (Model No.: ET-D3LEU100C),
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-D3LEW200C) or the Fixed-focus Lens
(Model No.: ET-D3LEU100C), 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"
(x page 204).
rDo not install the projector at an altitude of 4 200 m (13 780') or higher above sea
level. (Altitude of 4 200 m (13 780') above sea level is the maximum height that the
performance of this projector is guaranteed.)
rDo not use the projector in a location where the ambient temperature exceeds 45 °C
(113 °F).
Using the projector in a location where 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
45 °C (113 °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 40 °C (104 °F)
Do not use the projector in a location where the ambient temperature exceeds 40 °C (104 °F) regardless of the
altitude when the optional Wireless Module (Model No.: AJ-WM50MC) is attached to the projector.
