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 perform- ance.

•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.

•Utilize optical offset prior to tilting or aiming projector at screen.

•Keep optics, lens and port glass clean for best performance and image quality.

	Note	• Allow at least 50 cm clearance around the exhaust vent.
	Note	• Ensure that the intake vents do not recycle hot air from the exhaust vent.
