Precautions for use
Cautions when transporting
f Before using the projector, remove the dust sponge from the mounting portion of the projection lens and store it
for the future use. When transporting the projector, remove the projection lens before attaching the dust sponge.
Otherwise dust will accumulate inside and may cause malfunctions.
f Transport the projector with 2 or more people. Failure to do so may drop the projector, which may result in
damage or deformation of the projector, or injury.
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 attaching the projection lens, be sure to attach the lens mount cover.
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 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 malfunctions.
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 should be between 0 °C (32 °F)
and 40 °C (104 °F) when using it at high altitudes (between 1 400 m (4 593') and 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 it at elevations lower than 1 400 m (4 593') above sea
level, and should be between 0 °C (32 °F) and 35 °C (95 °F) when using it at high altitudes (between 1 400 m
(4 593') and 2 700 m (8 858') above sea level). If you use the Replacement lamp unit (for portrait mode)
together with the smoke cut lter, the operating environment temperature should be between 0 °C (32 °F) and
30 °C (86 °F). (Only for PT-DZ21K2, PT-DS20K2, PT-DW17K2)
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 projection 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 is required.
Model No.: ET-PKD520H (for high ceilings), ET-PKD520S (for low ceilings), ET-PKD520B (Projector Mount
Bracket)
rAsk a qualied technician or your dealer to install the cable wiring for DIGITAL LINK
connection.
Image and sound may be disrupted if cable transmission characteristics cannot be obtained due to inadequate
installation.
