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/LAN> 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. It is recommended that images be projected continuously for at least
30 minutes before the focus is adjusted.
rDo not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
Doing so may shorten the life of the components and result in malfunctions.
rDo not use the projector tilted to the right or left.
Using the projector at a vertical angle that exceeds ±15° may reduce product life or result in malfunction.
rCautions when setting up the projector
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 When installing the projector in a location other than on the floor using the adjustable feet or the ceiling mount,
use the five screw holes for ceiling mount for fixing the projector (as shown in the figure).
(Screw diameter: M6, tapping depth inside the projector: 12 mm (15/32"), torque: 4 ± 0.5 N·m)
Make sure that there is no clearance between the screw holes for ceiling mount on the projector bottom and the
setting surface by inserting spacers (metallic) between them.
f Do not stack projectors on top of each other.
f Do not use the projector supporting it by the top.
f Do not use the projector tilted at an angle that exceeds ±15° from the horizontal plane.
f Do not block the ventilation ports (intake and exhaust) of the projector.
