Precautions for use
Cautions when transporting
f The projection lens (optional) is susceptible to effects due to vibration or impact. Make sure to remove the lens when
transporting.
f 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.
f Do not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.
Cautions when installing
rAfter removing the projection lens (optional), attach the dust sponge included with the
projector.
Otherwise dust will accumulate inside and may cause malfunctions.
rDo not set up the projector outdoors.
The projector is designed for indoor use only.
rDo 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 Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may uctuate 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.
f Places with sharp temperature uctuations such as near lights (studio lamps): Doing so may shorten the life of the lamp, 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) when using it at
elevations lower than 1 400 m (4 593') above sea level, and between 0 °C (32 °F) and 40 °C (104 °F) when using it at high
altitudes (1 400 m (4 593') or higher – lower than 2 700 m (8 858') above sea level).
If you use the Smoke cut lter, the operating environment temperature should be between 0 °C (32 °F) and 35 °C (95 °F).
However, it cannot be used at high altitudes.
If you use the Replacement lamp unit (for portrait mode), the operating environment temperature should be between 0 °C
(32 °F) and 40 °C (104 °F) when using the projector at elevations lower than 1 400 m (4 593') above sea level, and between
0 °C (32 °F) and 35 °C (95 °F) when using the projector at high altitudes. If you use the Smoke cut lter together, the
operating environment temperature should be between 0 °C (32 °F) and 30 °C (86 °F).
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
chips.
rBe sure to ask a specialized technician or your dealer when installing the projector on
a ceiling.
The optional Ceiling Mount Bracket for Projectors is required.
Model No.: ET-PKD310H (for High Ceilings), ET-PKD310S (for Low Ceilings)
rLens 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.
rMake sure to set [HIGH ALTITUDE MODE] to [ON] when using the projector at
elevations between 1 400 m (4 593') or higher and lower than 2 700 m (8 858') above
sea level.
Failure to do so may shorten the life of the components and result in malfunctions.
rMake sure to set [HIGH ALTITUDE MODE] to [OFF] when using the projector at
elevations lower than 1 400 m (4 593') above sea level.
Failure to do so may shorten the life of the components and result in malfunctions.
rDo 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.
