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
Locations near the sea or areas affected by corrosive gas: Corrosion may damage internal components or cause the
projector to malfunction.
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 lamp, or
result in deformation of the outer case 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.
r
Ask a qualified technician or your dealer for the installation work such as installing to
a ceiling.
To ensure projector performance and safety, ask a qualified technician or your dealer when installing to a ceiling or in a high
place.
r
Focus adjustment
The 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 the images be projected continuously for at least 30 minutes before the focus
is adjusted.
r
When using the projector in the elevation of below 700 m (2 297'), make sure [High
land] is set to [Off].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
r
When using the projector in the elevation of above 700 m (2 297
'
) and below 1 400 m
(4 593
'
), make sure [High land] is set to [On 1].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
r
When using the projector in the elevation of above 1 400 m (4 593') and below 2 700 m
(8 858'), make sure [High land] is set to [On 2].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
r
Do not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
Failure to do so may shorten the life of the internal parts and result in malfunctions.
r
Do not tilt the projector or place it on its side.
Do not tilt the projector body more than approximately ±30 degrees vertically or ±15 degrees horizontally. Over tilting may
result in shortening the life of the components.
