31 Using the projector
Eng
lish 5. Real: This setting displays the image in a one-to-one pixel mapping
without alteration or resize in the centre of the projection. This is most
suitable for use with PC and RGBHD source inputs.
The black portions are inactive areas and the white portions are active areas.
OSD menus can be displayed on those unused black areas.
Using Panamorph lenses (optional)
Panamorph lenses allow you to convert 16:9 projectors to the full 2.35:1 aspect ratio of most of major motion
pictures, showing the best movies without letterbox bars at top and bottom of images while increasing resolution
by 33% and brightness by 20%.
You may need a 2.35:1 screen to display the 2.35:1 images.
For more information, please go to www.panamorph.com or contact the place you purchase the projector.
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.
