Operating in a high altitude environment

We recommend you use the High Altitude Mode when your environment is between 1500 m –3000 m above sea level, and temperature is between 0°C–35°C.

Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and temperature is between 0°C and 35°C. The projector will be over cooled, if you turn the mode on under such condition.

English

To activate the High Altitude Mode,

1.Press MENU/EXIT and then press / until the SYSTEM SETUP: Advanced menu is highlighted.

2.Press to highlight High Altitude Mode and press / to select On. A confirmation message displays.

3.Highlight Yes and press ENTER.

Operation under High Altitude Mode may cause a higher decibel operating noise level because of increased fan speed necessary to improve overall system cooling and performance.

If you use this projector under other extreme conditions excluding the above, it may display auto shut-down symptoms, which is designed to protect your projector from over-heating. In cases like this, you should switch to High Altitude mode to solve these symptoms. However, this is not to state that this projector can operate under any and all harsh or extreme conditions.

WARNING

We recommend you use the High Altitude Mode by selecting it whenever your environment is higher than 1500 m.

Do you want to turn High Altitude Mode on?

YesNo
