BenQ ALR
Screen
Enabling this feature will optimize the picture mode for BenQ ALR screens.
Please ensure that you have installed the ALR screen before turning on this
feature.
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.
12V Trigger
There is a 12V trigger that works independently according to your needs for
installation scenarios.
• On: If this is selected, the projector will send electronic signal out when it is
turned on.
• Off: If this is selected, the projector will not send electronic signal out when
it is turned on.
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.
