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
IMPORTANT SAFETY NOTICE
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.
Intended use of the product
The purpose of the projector is to project a video signal from imaging equipment or a computer on a screen or other surface
as a still image or moving image.
Cautions when transporting
When transporting the projector, move the lens position to the home position and attach the lens protection material when
transporting. Lens optional model, move the lens position to the home position, remove the projection lens, and attach the
lens hole cover when transporting.
Lens home position moving procedure.
1) Press the [DEFAULT] button on the remote control while
displaying the lens shift adjustment screen.
2) Press [q] [w] to select [OK], and press the [ENTER] button.
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.
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.
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 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 compo-
nents 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 dam-
age to the DLP chips.
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
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”.
