Operation 49

High Altitude Mode

It is a mode for operation in areas like high altitude or high temperature. Activate

the function when your environment is between 1500m – 3000m above sea level

and ambient temperature is between 0°C–30°C.

Do not use the High Altitude Mode if your altitude is between 0 m and 1500

m and temperature is between 0°C and 30°C. The projector will be over

cooled, if you turn the mode on under such a condition.

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.

security for the projector. See "Utilizing the password function" on page 35 for

When you select Off, the LED indicators are off after you turn on the projector

and the splash screen displays. However, if the projector is not working properly,

the LED indicators light or flash to remind you that a problem may occur. See also

"Indicators" on page 62 for more details.

The following settings will still remain: ISF, Reset Lamp Timer,

Power On Lock, High Altitude Mode, Password.

ISF

The ISF calibration menu is password protected and only accessible by authorized

ISF calibrators. The ISF (Imaging Science Foundation) has developed carefully

crafted, industry-recognized standards for optimal video performance and has

implemented a training program for technicians and installers to use these

standards to obtain optimal picture quality from BenQ video display devices.

Accordingly, we recommend that setup and calibration be performed by an ISF

certified installation technician.
