CAUTION
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and temperature
is between 5°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" may cause a higher

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.
