We recommend you use the High Altitude Mode
High Altitude Mode
High Altitude Mode
High Altitude Mode when your environment is between 1500 m 
–3000 m above sea level, and ambient 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 ambient 
temperature is between 0°C and 35°C. The projector will be over cooled, if you turn the mode 
on under such a condition.

Operation under "High Altitude Mode
High Altitude Mode
High Altitude Mode
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.
