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.
Select a baud rate that is identical with your computer's so that you can connect
the projector with a suitable RS-232 cable and update or download the projector's
firmware. This function is intended for qualified service personnel.
