Precautions for use
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 cause the projector to fall off, shorten
the life of the parts 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 main
unit of the projector.
f
Places with sharp temperature fluctuations near lights (such as studio lamps): Doing so may result in
deformation of the projector due to heat, which may cause malfunctions.
The operating environment temperature of the projector should be between 0 °C (32 °F) and 40 °C (104 °F)
when using it at elevations lower than 1 000 m (3 281') above sea level, and between 0 °C (32 °F) and 35 °C
(95 °F) when using it at elevations between 1 000 m (3 281') and 2 700 m (8 858') above sea level.
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 lens surface causes damage
to the DLP chip.
r
Do 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.
r
Ensure that track system is installed per manufacturer’s instructions and in
accordance with the National Electrical Code and local building codes.
Inadequate installation may result in fire, electric shocks or falling of the projector.
r
Mount the projector to the track system which is installed in the horizontal ceiling or
beam and can withstand the weight of the projector (
x
page 147).
Mounting the projector to the following track system will result in fire, electric shocks, or falling of the projector.
f
Track system that is installed in the wall surface
f
Track system that is installed in the sloping ceiling or beam
f
Track system that cannot withstand the load
f
Track system that is installed on the floor
Cannot be installed
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 images be projected continuously for at least 30 minutes
before the focus is adjusted.
r
Cautions when setting up the projector
f
Do not block the ventilation ports (intake and exhaust) of the projector.
