Front & Rear IR Sensors
The two IR sensors located on the projector receive transmissions from the IR remote from up to 100 feet
away. It is important to keep the transmission path to these sensors unobstructed for uninterrupted
communications with the projector. The rear IR sensor is located at the back of the projector between the status
LEDs and the front IR sensor is located next to the projector's front nameplate.
Projection Lenses, Lens Mount and Other Features
The projector includes a motorized lens mount that allows automated lens control and adjustment: vertical and
horizontal offsets, zoom and focus. The lens mount can be fitted with any one of the available optional lenses –
see Section 7 Specifications.
• Zoom and Focus – There are two internal lens motors that allow for quick motorized adjustment of zoom
and focus. Adjust zoom to fit the displayed image on the screen and adjust focus to improve the clarity of the
image.
The projection lens is shipped separately from the projector.
NOTES: 1)
transporting the lens to avoid scratching and damaging the lens, which could affect your displayed image.
Motorized lenses should not be adjusted by hand without first setting them for manual operation,
3)
otherwise the zoom and focus motors may be damaged. (Set in Menu>Configuration>Lens
Settings>Manual Zoom/Focus).
• Lens Offset – The motorized lens mount allows vertical and horizontal offset of the displayed image.
• Shutter – Standard on all models, the shutter allows you to turn the screen absolutely black when in the
"Closed" state.
• Iris Contrast Aperture – Enables adjustment of light output and contrast ratio.
Ambient Lighting
The high brightness of this projector is well suited for locations where ambient lighting might be considered
less than ideal. A typical room with ceiling lights and windows rarely requires special attention. Contrast ratio
in your images will be reduced if stray light directly strikes the screen. For example, when a shaft of light from
a window or floodlight falls on the image. Images may appear washed out and less vibrant. Avoid or eliminate
stray light sources directed at the screen.
Ventilation
The projector vents and louvers provide ventilation, both for intake and exhaust. Never block or cover these
openings. Do not install the projector near a radiator or heat register, or within an enclosure. To ensure
adequate airflow around the projector, allow free air exchange to the projector with a minimum clearance of
25cm (10") on the left, right and rear sides of the projector from any walls or other obstructions.
obstruct the air exchange to the projector.
Other Considerations
Other considerations and tips to improve your installation:
• Keep the ambient temperature constant and below 40°C (104F). 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,
slide projectors, speakers, power amplifiers, elevators, etc.
