Positioning your projector

Choosing a location

Your room layout or personal preference will dictate which installation location you select.
Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location
and distance between the projector and the rest of your equipment.
Your projector is designed to be installed in the following installation locations:
1. Front Table
Select this location with the projector placed near the
floor in front of the screen. This is the most common way
to position the projector for quick setup and portability.
