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 wave, near the installation location, install the projector at a
location sufficiently far from the source of the radio wave. Or, wrap the LAN cable connected to the <DIGITAL LINK/LAN>
terminal by using a piece of metal foil or a metal pipe, of 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. Wait at least 30 minutes with the image projected before adjusting the lens focus.
rMake sure to set [HIGH ALTITUDE MODE] to [ON] when using the projector at
elevations between 1 400 m (4 593') or higher and lower than 2 700 m (8 858') above
sea level.
Failure to do so may shorten the life of the components and result in malfunctions.
rMake sure to set [HIGH ALTITUDE MODE] to [OFF] when using the projector at
elevations lower than 1 400 m (4 593') above sea level.
Failure to do so may shorten the life of the components and result in malfunctions.
rDo not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
Doing so may shorten the life of the components and result in malfunctions.
rDo not use the projector tilted to the right or left.
Using the projector at a vertical angle that exceeds 15° may reduce product life or result in malfunction.
rWhen using the Replacement lamp unit (for portrait mode), install the projector with
the terminals surface facing down.
Do not use the projector tilted to the right and left, front and back. Using the projector at an angle that exceeds 15° in either
direction may reduce the life of the components or result in malfunctions.
rCautions when setting up the projector
f When installing the projector at the section other than the floor by using the adjustable feet, use six screw holes for ceiling
mount for fixing the projector (as shown in the figure).
(Screw diameter: M6, tapping depth inside the set: 12 mm (15/32"), torque: 4±0.5 N·m)
f Make a clearance of at least 20 mm (25/32") between the projector bottom and the setting surface by inserting spacers
(metallic) between them.
f Use the adjustable feet only for the floor standing installation and for adjusting the angle. Using them for other purposes may
damage the projector.
f Do not stack projectors on top of each other.
f Do not use the projector supporting it by the top.
f Do not use the projector tilted at an angle that exceeds ±15° from the horizontal plane.
f Do not block the ventilation ports (intake and exhaust) of the projector.
