High Altitude Mode
It is a mode for operation in areas like high altitude or high temperature. 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 the High Altitude Mode if your altitude is between 0 m and 1500
m and temperature is between 0°C and 30°C. The projector will be over
cooled, if you turn the mode on under such a condition.
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.

certified installation technician.
