Operation under "High Altitude Mode
High Altitude ModeHigh 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.
