M-Series User Manual2-9020-100009-01 Rev.1 (07/08) FRONT SCREEN / INVERTED MOUNT (CEILING) INSTALLATION REAR SCREEN / FLOOR MOUNT INSTALLATION REAR SCREEN / INVERTED MOUNT (CEILING) INSTALLATION REAR SCREEN / FLOOR MOUNT WITH MIRROR FRONT SCREEN INSTALLATIONS In front screen installations, the projector and audience are positioned in front of the screen, which can be flat or curved. Flat screens offer a gain of about 1.0 with a viewing angle just less than 180°. This type of screen reflects incident light equally in all directions so the audience can see the display from various angles. Curved screens have a gain greater than 1.0 with a viewing angle much less than 180°. This type of screen does not reflect incident light equally in all directions; instead it is concentrated in a viewing cone. The audience sitting within the viewing cone area will see a brighter image than those sitting just outside the area. AdvantagesConsiderations • Does not take up audience space. • Projector is unobtrusive. • Projector cannot be accidentally moved.• Installation is more permanent. • It is more difficult to access the projector. AdvantagesConsiderations • Projector is completely hidden. • Projector is easily accessed. • Usually good ambient light rejection.• Requires separate room or enclosure. • Installation cost is usually higher. AdvantagesConsiderations • Projector is completely hidden. • Usually good ambient light rejection.• Requires separate room. • Installation cost is usually higher. • More difficult to access projector. AdvantagesConsiderations • Projector is completely hidden • Usually good ambient light rejection. • Requires less space behind screen than other rear screen installations.• Requires separate room or enclosure. • Installation cost is usually higher. • More involved to perform setup.
Section 2: Installation and Setup M-Series User Manual2-10020-100009-01 Rev.1 (07/08) REAR SCREEN INSTALLATIONS There are two basic types of rear screens: diffused and optical. A diffused screen has a surface which spreads the light striking it. Purely diffused screens have a gain of less than 1.0. The advantage of the diffused screen is its wide viewing angle, similar to that of a flat screen for front screen projection. This type of screen is suitable when a wide viewing angle is required but there is low ambient room lightening. Optical screens take light from the projector and redirect it to increase the light intensity at the front of the screen. This reduces it in other areas. A viewing cone, similar to that of a curved front screen installation is created. This type of screen is better suited for brightly lit rooms where the audience is situated within the viewing cone. SCREEN SIZE Choose a screen size appropriate for your lens and application. If the projector will be used to display text information, the image size must allow the audience to recognize all text clearly. The eye sees a letter clearly if eye-to-text distance is less than 150 times the height of the letter. Small text located too far from the eye will be illegible at a distance no matter how sharply and clearly it is displayed. To fill a screen with an image, the aspect ratio of the screen should be equal to the aspect ratio of the image (expressed as the ratio of its width to its height). Standard video from a VCR has a 4:3 or 1.33:1 aspect ratio. For example, to display a VCR output with a 4:3 aspect ratio onto a 10-foot (3m) high screen, the width of the screen must be at least 13.3 feet (4m). 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.

M-Series User Manual2-11020-100009-01 Rev.1 (07/08) 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. NOTE: Do not 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 heat- ing 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 trans- formers, slide projectors, speakers, power amplifiers, elevators, etc. • Use a screen size appropriate for the venue but not larger than required. Installing a large screen in a small room is similar to watching television at a close range; too large a screen can overpower a room and interfere with the overall effect. As a rule, be no closer than 1.5 times the width of the screen. 2.2.3Projector Position and Mounting THROW DISTANCE Throw distance is the distance measured from your projector’s front feet to the screen. This calculation determines if there is enough room to install your projector with a desired screen size and if the image will be of the right size for your screen. To estimate the throw distance take the horizontal width of the screen and multiply it by the lens throw ratio. The result determines approximately the distance the projector should be positioned from the screen to project a focused image large enough to fill the screen. For example, using a 0.73:1 lens, throw distance would roughly be 0.73 x screen width. IMPORTANT: Use the lens and screen size to calculate the precise throw distance using the tables provided in the Dealer Section of the Christie Website, PN 020-100221-XX. Due to lens manufactur- ing tolerances for lens focal length, actual throw distance can vary ±5% between lenses with the same nominal throw ratio. FIGURE 2-8 - THROW DISTANCE
Section 2: Installation and Setup M-Series User Manual2-12020-100009-01 Rev.1 (07/08) VERTICAL AND HORIZONTAL POSITION The correct vertical and horizontal position of the projector in relation to the screen depends on the lens type and the screen size. Ideally, the projector should be positioned perpendicular to the screen. This way, the image will appear rectangular instead of keystoned (trapezoidal). The vertical position of the image can be offset (that is moved above or below the optical axis) by adjusting the motorized lens mount. The amount of vertical offset available depends on the type of lens installed in the projector and can be limited if horizontal offset has been applied. Vertical offset can be expressed as the percent of half the image height or the number of pixels of shift from lens center. Refer to Figure 2-9 - Vertical Offset Examples for illustrated examples of vertical offset. Ta b l e 2 . 1 and Ta b l e 2 . 2 specify the vertical offset of each type of lens.

M-Series User Manual2-17020-100009-01 Rev.1 (07/08) 2.2.4Mounting There are several methods for mounting the projector. In typical front and rear screen installations the projector can be mounted to a secure and level surface, such as a table or cart. Carts are useful when the projector has to be moved often. Lock the wheels on a cart, when it is in position, to prevent accidental movement during a presentation. CEILING MOUNT The projector can be inverted and suspended from the ceiling using a specially designed ceiling mount fixture 118-100108-XX. This mounting is recommended for those that want the projector out of plain view or have limited amount of space for the projector. For more information, contact your dealer. SPECIAL MOUNTING The projector can also be rotated (front-to-back) up to 360 degrees and fixed in a rotated position without affecting performance. However, the side-to-side tilt limit of the projector must not exceed +/- 15 degrees, to ensure optimal performance of the projector. 2.2.5Adjusting Projector Height/Tilt ADJUSTING HEIGHT You can modify the height of the projector to remedy a slightly uneven mounting surface by adjusting the three feet threaded into the bottom chassis. Turn each foot clock-wise or counter-clockwise until the projector is level on all sides. The front feet are adjusted by turning the collar, see Figure 2-11 - Front Foot. The front feet do not rotate when adjusted. The rear foot is adjusted by turning the entire foot, see Figure 2-12 - Rear Foot. Use only the CHRISTIE approved ceiling mount kit designed for your projector. Refer to the installation instructions and safety guidelines provided in the kit.

Section 2: Installation and Setup M-Series User Manual2-18020-100009-01 Rev.1 (07/08) ADJUSTING TILT 1. Before adjusting tilt, ensure the projector is centered. NOTE: Check with site personnel for the degree of screen tilt, or measure this incline with a protractor at the screen. 2. Then tilt the projector to closely match the screen tilt angle by extending or retracting the projector’s 3 adjustable feet. NOTE: 1) For an ideal installation, the lens surface should be centered and parallel to the screen - this orientation helps to ensure optimized lens performance with minimal offset. Choose a sturdy mounting surface that allows for this. If this position is not possible (such as when the projector is significantly higher than the center of the screen), it is better to rely on offset rather than extra tilt. 2.2.6Basic Optical Alignment Only perform image alignment once the projector is fully assembled and powered up in its final location. Basic image alignment ensures the image reflected from the DMDs is parallel to and well- centered with the lens and screen. This initial optical alignment is the foundation for optimizing images on the screen and must be completed before final boresight adjustments. Before beginning ensure the projector is properly positioned relative to the screen. BASIC OPTICAL ALIGNMENT PROCEDURE 1.Display a test pattern: Appropriate for analyzing image focus and geometry, such as the “framing” test pattern showing the cross-hair centered across the image. Press the (Test) key on the remote keypad or use the built-in keypad and press the soft key that displays Test on the LCD display. 2.Course focus: Do a quick preliminary focus and (if available) zoom adjustment with the primary lens. Do not worry about consistency across the image at this point, just center focus. It is good practice to have zoom adjustment color and focus adjustment color in the center of its range. 3.Center the image in the lens: Holding a piece of paper at the lens surface, adjust offsets as necessary until the image is centered within the lens perimeter. A full white field works best for this. 4.If necessary, center the image on the screen: If the projector is mounted off center to the screen axis, then offset the lens as much as required. Aim the projector over slightly towards the center of the screen, but use caution when doing so, as too much tilt will cause excessive keystone distortion. Lens offset will not. 5.Re-check side-to-side leveling: With the framing pattern on screen, double-check projector leveling so the top edge of the image is parallel to the top edge of the screen. 6.Throw Distance: Ensure the projector is positioned in the throw distance range for the particular lens. FOLDED OPTICS In rear screen applications where space behind the projector is limited, a mirror may be used to fold the optical path. The position of the projector and mirror must be accurately set - if considering this type of installation call your dealer for assistance. Te s t
