image. Anamorphic is most suitable for images which are already in a 16:9 aspect, like high definition
TV, as it displays them without aspect alteration.
6. Letter Box: Scales a picture to fit the projector’s native resolution in
its horizontal width and resize the picture’s height to the 3/4 of the
projection width. This may produce a picture greater in height than
can be displayed, so part of the picture is lost (not displayed) along the
top and bottom edges of the projection. This is suitable for the display
of movies which are presented in letter box format (with black bars
on the top and bottom).

Operating in a high altitude environment
We recommend that 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/EXIT and then press / until the System Setup : Advanced menu is highlighted.
2. Press to highlight High Altitude Mode.
3. Press / to select On. A confirmation message displays.
4. 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.
