Precautions for use
Cautions when transporting
f
If you purchased the projector with the standard zoom lens, remove the lens cushion before use, and store it for the future
use. When transporting the projector, move the lens position to the home position and attach the lens cushion.
If you purchased the projector with the lens sold separately, remove the lens hole cover before use, and store it for the future
use. When transporting the projector, move the lens position to the home position, remove the projection lens, and then
attach the lens hole cover.
For the steps to move the lens to the home position, refer to “Moving the lens to the home position” (

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
r
After attachment of the projection lens, be sure to attach the Lens Mount Cover.
Otherwise dust will accumulate inside and may cause malfunctions.
r
Do not set up the projector outdoors.
The projector is designed for indoor use only.
r
Do 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 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 projector.
f
Places with sharp temperature fluctuations 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 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.
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.
r
Be 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-PKD120H (for high ceilings), ET-PKD120S (for low ceilings), ET-PKD120B (Projector Mount Bracket)
r
Ask a qualified 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.
