Any unauthorized changes or modifications to this equipment will void the users authority to operate.
Cautions when transporting
When transporting the projector, move the lens position to the home position and attach the lens cushion.
  If lens optional model, move the lens position to the home position, remove the projection lens, and then attach
  the lens hole cover.
Unpacking and carrying should be done by at least two persons.
When transporting the projector, hold it securely by its bottom and avoid excessive vibration and impacts.
  They may damage the internal components and result in malfunctions.
Do not transport the projector with the adjustable feet extended.
  Doing so may damage the adjustable feet.
Do not set up the projector in the following locations.
The projector is designed for indoor use only.
Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal
  components or 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. 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 outer case due to heat, which may cause malfunctions.
The operating environment temperature of the projector should be between 0 °C (32 °F) and 45 °C (113 °F).
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 lens surface causes damage
  to the DLP chips.
Note at the time of installation
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.
  It is recommended that images be projected continuously for at least 30 minutes before the focus is adjusted.
Be sure to set [HIGH ALTITUDE MODE] to [OVER 2700m] when using the projector at elevations between
  2 700 m (8 858') and 4 200 m (13 780') above sea level.
  Make sure to set [HIGH ALTITUDE MODE] to [UNDER 2700m] when using the projector at elevations lower
  than 2 700 m (8 858') above sea level.
  Do not install the projector at elevations of 4 200 m (13 780') or higher above sea level.
・Set [COOLING CONDITION] according to the projection direction, but set it to [AUTO] most commonly.
  Using the projector with [COOLING CONDITION] set incorrectly may shorten the life of the light source.
  Check the setting from [COOLING CONDITION] on the [STATUS] screen.
 There are special parts used in Panasonic DLP Projectors which are important for safety. These parts are shaded on the schematic

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own
