Description
It is recommended that you use High Altitude
Mode when your environment is between 1,500-
3,000 m above sea level, and a temperature
between 5°C-25°C.
NOTE: 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.
Reset the Settings to default.
