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.
Baud Rate
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.
