Vertical Lens Shift: The PD7170 provides up to 65% of vertical lens shift up or
down. For example, with a 100 x 56 inch (1.78:1) screen, you can shift the image
up to 36.40 inches (0.92 meters) above or below the screen center.
Horizontal Lens Shift: The PD7170 provides up to 30% of horizontal lens shift left or
right. For example, with a 100 x 56 inch (1.78:1) screen, you can shift the image
up to 30.00 inches (0.76 meters) left or right of 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 3-6. 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 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 are for ceiling mount
configurations. For floor installations (where the projector
is upright), reverse the up/down vertical lens shift
percentages.
