22 - ENGLISH
r
Ask a qualified technician or your dealer for the installation work such as installing to
a ceiling, etc.
To ensure projector performance and safety, ask a qualified technician or your dealer when installing to a ceiling or
in a high place.
r
Ask 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.
r
The 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/LAN> terminal using a piece of metal foil or a metal pipe which is grounded at both ends.
r
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.
It is recommended to perform the focus adjustment after 30 minutes have elapsed with the focus test pattern
displayed. For details of the test pattern, refer to “[TEST PATTERN] menu” (

page 157).
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 45 °C
(113 °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.

Projection in all 360° direction is possible.
