(Indicated on the projector
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 commer-
cial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the instruction 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.
To assure continued compliance, follow the attached installation instructions. This includes using the provided power cord and shield-
ed interface cables when connecting to computer or peripheral devices. Also, any unauthorized changes or modifications to this equip-
ment could void the user’s authority to operate this device.
Notes on repairing
In case of fuse opening inside the projector, Do not turn the projector on just replacing the fuse with new one because there
might be a possibility to have smoking or firing hazard. Turn it on after solving the main cause of fuse opening.
After repairing, confirm that the projector operates correctly.
Pay attention to handle the projector as customer's personal settings have been remaining inside the projector.
Cautions when transporting
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.
Hold the bottom of the projector and do not hold the projection lens or the opening around the projection lens when trans-
porting. Failure to do so may cause damage. Also, handle the projector in a way not to apply excessive vibration or shock.
Failure to do so may cause a failure due to the damaged internal components.
Do not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.
Cautions when installing
Do not set up the projector outdoors.
The projector is designed for indoor use only.
Do not use under the following locations.
Places where vibration and impacts occur such as in a car or vehicle: Doing so may damage the internal parts and result in
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 malfunction.
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 equip-
ment, or the air from the air conditioner does not blow toward the front of the projector.
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 outer case due to heat, which may cause malfunction. Follow the operating environ-
ment of the projector.
Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
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
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.
About lead free solder (PbF)
This projector is using the P.C.Board which applies lead free solder.
Use lead free solder in servicing from the standpoint of antipollution for the global environment.
• Lead free solder: Sn-Ag-Cu (tin, silver and copper) has a higher melting point (approx. 217°C) than standard solder Typically
the melting point is 30~40 °C higher. When servicing, use a high temperature soldering iron with temperature limitation func-
tion and set it to 370 ± 10 °C.
• Be precautious about lead free solder. Sn-Ag-Cu (tin, silver and copper) will tend to splash when heated too high (approx.
600°C or higher).
• Use lead free solder for the P.C.Board (specified on it as “PbF”) which uses lead free solder. (When you unavoidably use lead
solder, use lead solder after removing lead free solder. Or be sure to heat the lead free solder until it melts completely, before
applying lead solder.)
• After solder to double layered P.C Boards, check the component side for excess solder which may flow onto the opposite side.
About the identification of the lead free solder P.C.Board.
For the P.C.Board which applies lead free solder, the symbol as shown in the figure below is printed or stamped on the surface
or the back of P.C.Board.
There are special components used in this equipment which are important for safety. These parts are marked by 7 in the
schematic diagram, 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.
IMPORTANT SAFETY NOTICE
Projection in all 360° direction is possible.
(Combination of vertical and horizontal)
Cautions when setting up the projector
Use the adjustable feet only for the floor standing installation and for adjusting the angle. Using them for other purposes
may damage the projector.
Do not stack projectors on top of each other.
Do not use the projector supporting it by the top.
Do not block the ventilation ports (intake and exhaust) of the projector.
Prevent hot and cool air from the air conditioning system to blow directly to the ventilation ports (intake and exhaust) of the
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.
The high clarity projection lens is thermally affected by the light from the light source, making the focus unstable in the pe-
riod just after switching on the power. When the [PROJECTOR SETUP] menu → [LENS] → [ACTIVE FOCUS OPTIMIZER]
is set to [OFF], it is recommended to perform the focus adjustment after 30 minutes or more have elapsed with the focus
test pattern displayed.
For details of [ACTIVE FOCUS OPTIMIZER], refer to the [PROJECTOR SETUP] menu → [LENS] → [ACTIVE FOCUS OP-
For details of the test pattern, refer to “[TEST PATTERN] menu”.
Do not install the projector at an altitude of 2 700 m (8 858') or higher above sea level.
Do not use the projector in a location that the ambient temperature exceed 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.
