Operating in a high altitude environment

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–35°C.

To activate the High Altitude Mode:

1.

Press Menu/Exit and then press  /  until the SYSTEM SETUP: Advanced menu 
is highlighted.

2.

Press   to highlight High Altitude Mode and press 

/

 select On. A 

confirmation message displays.

3.

Highlight Yes and press Mode/Enter.

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.

Locking control keys

With the control keys on the projector locked, you can prevent your projector settings 

from being changed accidentally (by children, for example). When the Panel Key Lock is 
on, no control keys on the projector will operate except   Power.

menu, and select On by pressing
