Precautions for use
Intended use of the product
The product is intended to project still/moving image signals from video equipment and computers onto a screen.
Cautions when transporting
f
When transporting the projector, hold it securely by its bottom and avoid excessive vibration and impacts. Doing
so may damage the internal parts and result in malfunctions.
f
Do not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.
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 exhaust vent or the hot or cooled air from an air conditioner. 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 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.
f
Places where there is high-power laser equipment: Directing a laser beam onto the projection lens surface
causes damage to the DLP chips.
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 below 1 400 m (4 593') above sea level, make sure [High
Altitude] is set to [Off].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
r
When setting [Light Power] to [Normal] and using the projector between 1 400 m (4
593') and 2 100 m (6 890') above sea level, make sure [High Altitude] is set to [High 1].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
r
When setting [Light Power] to [Normal] and using the projector between 2 100 m (6
890') and 2 700 m (8 858') above sea level, make sure [High Altitude] is set to [High 2].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
r
When setting [Light Power] to [Eco] or [Quiet] and using the projector between 1 400
m (4 593') and 4 200 m (13 780') above sea level, make sure [High Altitude] is set to
[High].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
