The Vision 70 provides up to 40% of vertical lens shift above and up to 50% of vertical
lens shift below the screen center. For example, with a 96 x 54-inch (16:9) screen, you can
shift the image up to 21.60 inches (0.55 meters) above or 27.00 inches (0.69 meters) below
the screen center.
Folded Optics
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 3-4. 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.
