Precautions for use
Cautions 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
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 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.
f Near lights (studio lamps, etc.) and other locations with severe temperature uctuations (when using at a place lower than
1 400 m (4 593') above sea level: operating temperature of 0 °C (32 °F) to 45 °C (113 °F), when using at a place of 1 400 m
(4 593') to 2 700 m (8 858') above sea level: operating temperature of 0 °C (32 °F) to 40 °C (104 °F)): The outer case may
be deformed by heat, which may result in malfunctions.
f Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
f Place 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 to
a ceiling.
The optional ceiling mount bracket is required.
Model No.: ET-PKR100H (for high ceilings), ET-PKR100S (for low ceilings), ET-PKR100P (for portrait)
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.
rThe projector may not work properly due to strong radio wave from the broadcast
station or the radio.
If there is any facility or equipment, which outputs strong radio wave, near the installation location, install the projector at a
location sufciently far from the source of the radio wave. Or, wrap the LAN cable connected to the <DIGITAL LINK/LAN>
terminal by using a piece of metal foil or a metal pipe, of which is grounded at both ends.
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') and 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 high altitudes of 2 700 m (8 858') or higher above sea
level.
Doing so may shorten the life of the components and result in malfunctions.
