Operating in a high altitude environment
We recommend you use the
High Altitude Mode
when your environment is between
1500 m –3000 m above sea level, and 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 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 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.
