Section 2: Installation and Setup
Lamp Door
The lamp doors are located at the side of the projector, which provides easy access to the lamp module for
replacement. The lamp doors are fitted with safety interlocks which switch the lamp off when the door is
opened. The lamp doors are provided with clear windows to indicate when the lamps are on.
Front and Rear IR Sensors
The two IR sensors 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. The front IR sensor is located
next to the 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.
• 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.
NOTES: 1) The projection lens is shipped separately from the projector. 2) Use the lens cap when
transporting the lens to avoid scratching and damaging the lens, which could affect your displayed image. 3)
Motorized lenses should not be adjusted by hand without first setting them for manual operation, 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: Allows the screen to become absolute black, when in the "closed" state.
• Dynamic Iris Contrast Aperture: Enables adjustment of light output and contrast ratio.
NOTE: Dynamic Iris is only applicable on 200W and 350W models.
