For US
Any unauthorized changes or modifications to this equipment will void the users authority to operate.
Do not set up the projector in the following locations.
Do not set up the projector outdoors. The projector is designed for indoor use only.
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.
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.
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.
Cautions when setting up the projector
Mount the projector to the track system which is installed in the horizontal ceiling or beam and can withstand the weight of the projector.
Do not install the projector in a confined space, and do not block the ventilation ports (intake and exhaust) of the projector.
Prevent hot and cool air from the air conditioning system to blow directly to the ventilation ports (intake and exhaust) of the projector.
Make sure to set [HIGH ALTITUDE MODE] to [HIGH1] when using the projector at elevations between 1 000 m (3 281') and 
2 000 m (6 562') above sea level, and set [HIGH ALTITUDE MODE] to [HIGH2] when using the projector at elevations between 
2 000 m (6 562') and 2 700 m (8 858').
Do not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
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.
 There are special parts used in Panasonic DLP Projectors which are important for safety. These parts are shaded on the schematic
 diagram. It is essential that these critical parts should be replaced with manufacturer’s specified parts to prevent shock, fire, or other
 hazards. Do not modify the original design without permission of Panasonic System Communications Company of North America.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following measures:
    ・Reorient or relocate the receiving antenna.
    ・Increase the separation between the equipment and receiver.
    ・Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
    ・Consult the dealer or an experienced radio/TV technician for help.
