Folded Optics In rear-projection 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.

Other Considerations Other considerations and tips that can help improve your installation:
• Keep the ambient temperature constant and below 35°C (95°F). Keep the projector 
away from heating and/or air conditioning vents. Changes in temperature may cause 
drifts in the projector circuitry, which may affect performance.
• Keep the projector away from devices that radiate electromagnetic energy such as 
motors and transformers. Common sources of these include slide projectors, 
speakers, power amplifiers and elevators.
1. With no lens shift, the lens center and screen center are aligned 
with each other.
2. Vertical shift limits are percentages of the screen height. 
3. Vertical lens shift figures are for ceiling mount 
configurations. For floor installations (where the projector is 
upright), reverse the up/down vertical lens shift percentages.
