   excessive vibration or shock. 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
 After attaching the projection lens, be sure to attach the Lens Mount Cover.
Not doing so may cause failure due to accumulating dust internally.
 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.
 Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal 
components or malfunction.
 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 malfunction.
 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 from the 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.
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.
Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
Places where there is high-power laser equipment: Directing a laser beam onto the projection lens surface 
causes damage to the DLP chips.
