PREFACE
There are special components used in this equipment which are important for safety. These parts are marked by 7 in the schematic dia-
gram, circuit board diagrams, exploded views and replacement parts list. It is essential that these critical parts should be replaced with
manufacturer's specified parts to prevent shock, fire, or other hazards. Do not modify the original design without permission of manufacturer.
Caution:
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environ-
ment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruc-
tion manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the interference at his own expense.
FCC Warning:
To assure continued compliance, follow the attached installation instructions. This includes using the provided power cord and shielded inter-
face cables when connecting to computer or peripheral devices. Also, any unauthorized changes or modifications to this equipment could void
the user's authority to operate this device.
Precautions for use
Cautions when transporting
f Transport the projector with four 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 front side and back side handles and avoid excessive
vibration and impacts. 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
rDo not set up the projector outdoors.
The projector is designed for indoor use only.
rDo 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.
rAsk a qualified technician or your dealer to do installation work such as mounting the
projector on the ceiling, including installation work that uses eyebolts.
To ensure projector performance and security, ask a qualified technician or your dealer when installing the
projector in a method other than the floor installation or when installing the projector in a high place.
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.
