High Altitude
Mode
We recommend you use the
High Altitude Mode
when your environment is
between 1,201 m to 3,000 m above sea level, and ambient temperature is
between 5°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 1,200
m and ambient temperature is between 0°C and 40°C. The projector will be
over cooled, if you turn the mode on under such a condition.
