Operating in a high altitude environment We recommend you activate High Altitude Mode when your environment is higher than 1500 meters (around 4920 feet) above sea level, or whenever the projector will be used for extended periods of time (>10 hours) without shutdown. To activate High Altitude Mode: 1. Press MENU and then press / until the Advanced Setup menu is highlighted. 2. Press to highlight High Altitude Mode. 3. Press / to select On. A confirmation message displays. 4. Highlight Yes and press 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.
