 Preparation — Precautions for use

18 - ENGLISH

rDo not use the projector in a location that the ambient temperature exceeds 50 °C 

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.
The upper limit of the operating environment temperature differs depending on the altitude or the setting of the 
[PROJECTOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE].

Altitude of 0 m (0') or higher 
to lower than 1 400 m 
(4 593')

0 °C (32 °F) to 50 °C (122 °F)

0 °C (32 °F) to 45 °C (113 °F)

Altitude of 1 400 m (4 593') 
or higher to lower than 
2 700 m (8 858')

0 °C (32 °F) to 45 °C (113 °F)

Altitude of 2 700 m (8 858') 
or higher to lower than 
4 200 m (13 780')

The projector cannot be used.

When the Smoke Cut Filter is used, the operating environment temperature should be between 0 °C (32 °F) and 

40 °C (104 °F) regardless of the [OPERATING MODE] setting. It cannot be used at an altitude of 1 400 m (4 593') 
or higher above sea level.

rProjection in all 360° direction is possible.

360°

360°

360°

360° vertically

360° horizontally

360° tilted

(combination of vertical and horizontal)

 

f

Install the projector in a place or with a mount that can sufficiently tolerate the weight. The position of the 

projected image may shift if the strength is not sufficient.

 

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.

 

f

The adjustable feet can be removed if not needed in the installation. However, do not use the screw holes 

where the adjustable feet were removed to fix the projector to a mount.
Also, do not insert any screws other than the eyebolts for the installation work into the screw holes of the 

adjustable feet. Do not insert the removed adjustable feet into other M10 screw holes.

 

f

Do not fix the projector to a mount with the screw holes for eyebolts (4 locations on each side) on the top side, 
right and left sides, and back side.

 

f

When installing and using the projector in a method other than the floor installation using the adjustable feet, 

remove the adjustable feet (4 locations) and use the six screw holes to fix the projector to a mount (as shown in 

the figure).

 Preparation — Precautions for use

ENGLISH - 17

 

f Transport the projector with four 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 front side and back side handles and avoid excessive 
vibration and impacts. Failure to do so may cause a failure due to the damaged internal components.

 

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.

r

To ensure projector performance and security, ask a qualified technician or your dealer when installing the 

projector in a method other than the floor installation or when installing the projector in a high place.

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.

rDo not install the projector at an altitude of 4 200 m (13 780') or higher above sea level.
