High Altitude
Mode
We recommend you use the
High Altitude Mode
when your environment is
between 1500 m –3000 m above sea level, and ambient temperature is between
0°C–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 and 35°C. The projector will be over cooled, if you turn the mode on
under such a condition.
