r
Be sure to ask a specialized technician or your dealer when installing the projector on
a ceiling.
The optional Ceiling Mount Bracket is required.
Model No.: ET-PKD120H (for High Ceilings), ET-PKD120S (for Low Ceilings), ET-PKD130B (Projector Mount
Bracket)
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 that images be projected continuously for at least
30 minutes before the focus is adjusted.
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.
The upper limit of the operating environment temperature differs depending on the altitude or the setting of the

purposes may damage the projector.
