Notes:

 

 

 

 

 

 

 

 

1. With no vertical or horizontal lens shift, the lens center and screen center are aligned with each

 

other.

 

 

 

 

 

 

 

 

2. Vertical shift limits are percentages of the screen height. Horizontal shift limits are percentages of

 

the screen width.

 

 

 

 

 

 

 

3. Vertical lens shift figures apply to ceiling mount configurations. For floor installations

 

(where the projector is upright), reverse the up/down vertical offset percentages.

 

 

 

 

 

 

 

 

 

 

 

In rear screen applications where space behind the projector is limited, a mirror may be

used to fold the optical path, as shown in Figure 3-5.The position of the projector and

 

mirror must be accurately set. If you are considering this type of installation, contact your dealer for assistance.
