The Vision 85 provides up to 50% of vertical lens shift in either direction. For example,
with a 96 x 54-inch (16:9) screen, you can shift the image up to 27.00 inches (0.69
meters)
above or below the screen center.
Folded OpticsIn 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.

Other ConsiderationsOther 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.
