Installation
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.
| Note | 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. | ||||

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.
