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.


Do not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.

Cautions when installing


Do not set up the projector outdoors.

The projector is designed for indoor use only.


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 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 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 exhaust vent or the hot or cooled air from the air conditioner. 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.


Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.


Ask a qualified technician or your dealer for the installation work such as installing to a ceiling.

To ensure projector performance and safety, ask a qualified technician or your dealer when installing to a ceiling or in a high place.


Chapter 1   Preparation — Precautions for use 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.


The 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 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.


Focus 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.


Do not install the projector at an altitude of 2 700 m (8 858') or higher above sea level.


Do not use the projector in a location that the ambient temperature exceeds 45 °C

(113 °F).

Using the projector in a location that the altitude is too high or the ambient temperature is too high may reduce the life of the components or result in malfunctions.


Projection in all 360° direction is possible.

360° 360° 360°

360° vertically 360° horizontally 360° tilted

(combination of vertical and horizontal) r

Cautions when setting up the projector

f Use the adjustable feet only for the floor standing installation and for adjusting the angle. Using them for other purposes may damage the projector.


When installing the projector with a method other than the floor installation using the adjustable feet or the ceiling installation using the ceiling mount bracket, use the four screw holes for ceiling mount (as shown in the figure) to fix the projector.

In such case, make sure that there is no clearance between the screw holes for ceiling mount on the projector bottom and the setting surface by inserting spacers (metallic) between them.

f Use a torque screwdriver or Allen torque wrench to tighten the fixing screws to their specified tightening torques.

Do not use electric screwdrivers or impact screwdrivers.

(Screw diameter: M6, tapping depth inside the projector: 12 mm (15/32"), screw tightening torque: 4 ± 0.5 N·m)
