 Preparation — Precautions for use

18 - ENGLISH

 

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.

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 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 light source, or result in deformation of the projector due to heat, which may cause malfunctions.
Follow the operating environment temperature of the projector.

 

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 

The optional Ceiling Mount Bracket is required.
Model No.: ET-PKD520H (for High Ceilings), ET-PKD520S (for Low Ceilings), ET-PKD520B (Projector Mount 
Bracket)

r

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 

If there is any facility or equipment which outputs strong radio waves near the installation location, install the 

projector at a location sufficiently far from the source of the radio waves. Or, wrap the LAN cable connected to the 

<DIGITAL LINK/LAN> terminal using a piece of metal foil or a metal pipe which is grounded at both ends.

rFocus adjustment

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. It is recommended that images be projected continuously for at least 
30 minutes before the focus is adjusted.

There are special components used in this equipment which are important for safety. These parts are marked by 7 in the schematic 

diagram, circuit board diagrams, exploded views and replacement parts list. It is essential that these critical parts should be replaced 

with manufacturer’s specified parts to prevent shock, fire, or other hazards. Do not modify the original design without permission of 

manufacturer.
