What are the different ways I can position my projector?

The projector can be installed in four configurations: Front Table (on floor in front of screen), Front Ceiling (suspended upside-down from ceiling in front of screen), Rear Table (on floor behind screen with special rear projection screen), and Rear Ceiling (suspended from ceiling behind screen). A projector mount is required for any ceiling installation, and a special rear projection screen is needed for rear projections. (Page 5)
