Precautions for use
Cautions when transporting
f
Before using the projector, remove the dust sponge from the mounting portion of the projection lens and store it
for the future use. When transporting the projector, remove the projection lens before attaching the dust sponge.
Otherwise dust will accumulate inside and may cause malfunctions.
f
Transport the projector with 2 or more people. Failure to do so may drop the projector, which may result in
damage or deformation of the projector, or injury.
f
When transporting the projector, hold it securely by its bottom and avoid excessive vibration and impacts. They
may damage the internal components and result in malfunctions.
f
Do not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.
Cautions when installing
r
Do not set up the projector outdoors.
The projector is designed for indoor use only.
r
Do not set up the projector in the following locations.
f
Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal
components or malfunction.
f
Location close to sea or where corrosive gas may occur: The projector may fall due to corrosion. Also, failure to
do so may shorten the life of the components and result in malfunctions.
f
Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may fluctuate in rare
cases due to the heated air from the air exhaust port or the hot or cooled air. Make sure that the exhaust
from the projector or other equipment, or the air from the air conditioner does not blow toward the front of the
projector.
f
Places with sharp temperature fluctuations such as near lights (studio lamps): Doing so may shorten the life of
the light source, or result in deformation of the projector due to heat, which may cause malfunctions.
Follow the operating environment temperature of the projector.
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.
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-PKD520H (for High Ceilings), ET-PKD520S (for Low Ceilings), ET-PKD520B (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.
