This chapter tells you how to set up the projector and connect it to a

want to place it on a table in front of 
the screen, as shown. 
This lets you stand in the front of the room, face the audience, and 
remain close enough to the equipment to be able to control it. Try to 
leave as much space as possible between the projector and...

Also keep these considerations in mind: 
■Place the projector on a sturdy, level surface.

under the projector. Do not set the projector on top of loose 
papers that could block the vents under the projector. 
■Make sure the projector is within 6 feet (2 m) of a grounded 
electrical outlet or extension cord. 
Try to place the projector directly in front of the center of the screen, 
facing it toward the screen...
