Eco Mode This setting reduces system noise and power consumption by 30%. If Eco Mode is selected, the light output will be reduced.
High Altitude
Mode
We recommend you use the High Altitude Mode when your environment is between 1500 m - 2000 m above sea level, and
ambient temperature is between 0 ˚ C to 30 ˚ C.
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.
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and ambient temperature is between 0 ˚ C to 35 ˚ C. The projector
will be over cooled, if you turn the mode on under such a condition.
