The mode is for operation in areas like high altitude or high temperature
environments. Activate the function when your environment is between 1500 m
–3000 m above sea level and ambient temperature is between 0°C–30°C.
Do not use this function if your altitude is between 0 m and 1500 m and
ambient temperature is between 0°C and 35°C. If you turn on the mode
under such a condition, the projector will be over cooled.
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.
