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 [OPERATING 

MODE] setting in the [PROJECTOR SETUP] menu → [OPERATION SETTING]   

 

Altitude of 0 m (0') or higher 

to lower than 1 400 m 

(4 593')

0 °C (32 °F) to 45 °C (113 °F)

0 °C (32 °F) to 40 °C (104 °F)

Altitude of 1 400 m (4 593') 

or higher to lower than 

2 700 m (8 858')

0 °C (32 °F) to 40 °C (104 °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 

35 °C (95 °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.

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

holes of the adjustable feet. Failure to do so may cause damage to the projector.

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

, 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.

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.

  - For continued safety, no modification of any circuit must be attempted.

  - Unplug the power cord from the power outlet before disassembling this projector.

  - Use correctly the supplied power cord and must ground it.

  - It is advisable to use an isolation transformer in the AC power line before the service.

  -  Be careful not to touch the rotation part (cooling fan, etc.) of this projector when you service with the upper case removed 

and the power supply turned ON.

  -  Observe the original lead dress during the service. If a short circuit is found, replace all the parts overheated or damaged 

by the short circuit.

  -  After the service, all the protective devices such as insulation barriers, insulation papers, shields, and isolation R-C combi-

nations must be properly installed.

  - After the service, check the leakage current to prevent the customer from getting an electric shock.

  1. Prepare the measuring circuit as shown in Fig.1.

    Be sure to use a voltmeter having the performance described in Table 1.

  2. Assemble the circuit as shown in Fig. 2. Plug the power cord in a power outlet.

  3. Connect M1 to T1 according to Fig. 2 and measure the voltage.

  4. Change the connection of M1 from T1 to T2 and measure the voltage again.

  5.  The voltmeter must read 0.375 V or lower in both of steps 3 and 4. This means that the current must be 0.75mA or  less.

  6.  If the reading is out of the above standard, the projector must be repaired and rechecked before returning to the customer 

because of a possibility of an electric shock.

set to [ECO], [LONG LIFE1], [LONG LIFE2], or [LONG LIFE3], the operating environment temperature should be between 0 °C (32 °F) and 40 °C 

(104 °F), regardless of the altitude. When the Smoke Cut Filter is used, the operating environment temperature should be between 0 °C (32 °F) and 

35 °C (95 °F).

When the [PROJECTOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE] is set to [ECO], [LONG LIFE1], [LONG LIFE2], or 

[LONG LIFE3], the projector cannot be used at an altitude of 2 700 m (8 858') or higher above sea level. When the Smoke Cut Filter is used, the 

projector cannot be used at an altitude of 1 400 m (4 593') or higher above sea level.

*5  When the [PROJECTOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE] is set to [NORMAL], and the operating environment 

temperature exceeds the following value, the light output may be reduced to protect the projector.

 

f

When using the projector at an altitude lower than 2 700 m (8 858') above sea level: 35 °C (95 °F)

 

f

When using the projector at an altitude between 2 700 m (8 858') and 4 200 m (13 780') above sea level: 25 °C (77 °F)

When the [PROJECTOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE] is set to [ECO], [LONG LIFE1], [LONG LIFE2], or 

[LONG LIFE3], and the operating environment temperature exceeds 35 °C (95 °F), the light output may be reduced to protect the projector.

 

f

The light output will decrease as much as the power supply voltage is decreased. It is recommended to use with AC 200 V or higher to 

prioritize luminance.
