Cautions when installing
■ Always attach the projection lens cover after attaching the projection lens.
If the cover is not attached, dust will accumulate inside and may cause malfunctions.
■ 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.
▶
z
Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to
internal parts or malfunction.
▶
z
Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may fluctuate in rare
cases due to the hot air from the air exhaust port or the heated 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.
▶
z
Near lights (studio lamps, etc.) and other locations of great temperature fluctuation (“Operating
environment” (
page 121)): Doing so may shorten the life of the lamp or result in deformation of the outer
case and malfunctions.
▶
z
Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
▶
z
Place where there is high-power laser equipment: Directing a laser beam onto the lens surface causes
damage to the DLP chips.
■ Be sure to ask a specialized technician or your dealer when installing the
product to a ceiling.
If the product is to be installed hanging from the ceiling, purchase an optional Ceiling Mount Attachment.
Model No.: ET-PKD56H (for high ceilings), ET-PKD55S (for low ceilings)
■ Lens focus
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. Wait at least 30 minutes with the image projected
before adjusting the lens focus.
■ Make sure to set [HIGH ALTITUDE MODE] to [ON] when using the projector
at elevations of 1 400 m (4 593 ft) or higher and lower than 2 700 m (8 858 ft)
above sea level.
Doing so may shorten the life of the internal parts and result in malfunctions.
■ Make sure to set [HIGH ALTITUDE MODE] to [OFF] when using the projector
at elevations lower than 1 400 m (4 593 ft) above sea level.
Doing so may shorten the life of the internal parts and result in malfunctions.
■ Do not install the projector at elevations of 2 700 m (8 858 ft) or higher above
sea level.
Doing so may shorten the life of the internal parts and result in malfunctions.
■ Do not use the projector tilted to the right or left.
Using the projector at a vertical angle that exceeds 15° may reduce product life or result in malfunction.
■ When installing and using the projector at an angle that exceeds 30°
vertically, set [COOLING CONDITION] (
page 67).
Failure to observe this will result in malfunctions or shorten the life of the lamp or other components.
