Precautions for use
Cautions when transporting
f
Transport the projector with two 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 impact. Failure
to do so may cause a failure due to the damaged internal components.
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
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” (
x
page 180).
r
Do not install the projector at an altitude of 4 200 m (13 780') or higher above sea level.
