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.

This projector supports CEC (Consumer Electronics Control) function for synchronized 

power on/off operation via HDMI connection. That is, if a device that also supports CEC 

function is connected to the HDMI input of the projector, when the projector’s power is 

turned off, the power of the connected device will also be turned off automatically. When 

the power of the connected device is turned on, the projector’s power will be turned on 

automatically.

To turn on the CEC function:

1.

Press MENU/EXIT on the projector or Menu on the remote control to open the On-
Screen Display (OSD) menu.
