Nortel Networks 822p User Manual

Before connecting the projector, you 
need to decide where to place it. If 
you’re setting up the projector yourself 
and it isn’t already installed in the 
room you’re using, you’ll probably 
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 the screen to 
get a good-size image. 

Place the projector somewhere between 3 and 30 feet from the screen. 
Use the figure below to help you determine exactly how far. Image size 
increases with distance, but can vary depending on how you’ve 
adjusted the optical zoom and other settings.

Also keep these considerations in mind: 

■

Place the projector on a sturdy, level surface.

■

Make sure there is plenty of space for ventilation around and 
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 meters) of a grounded 
electrical outlet or extension cord.
