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.
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 – 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. 
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 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.

Section 2: Installation and Setup
• 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.
2.2.2 Projector 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 manufacturing 
tolerances for lens focal length, actual throw distance can vary 
±5% between lenses with the 
same nominal throw ratio.
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 Table 2.1 for the 
vertical offset of each type of lens.

The horizontal position of the image can also be offset; that is moved to the left or right of optical center, by 
adjusting the motorized lens mount. The amount of horizontal offset available depends on the lens installed 
and if the image has already been vertically offset. Horizontal offset can be expressed as the percent of half the 
image width or the number of pixels of shift to one side of lens center. Refer to Table 2.2 for the horizontal 
offset of each lens type.

Section 2: Installation and Setup
2.2.3 Mounting
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.
 Only use Christie approved mounts designed for your projector. Refer to the
installation instructions and safety guidelines provided with the mount.
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.
2.2.4 Adjusting 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 2-10 Front Foot. The front feet do not rotate when 
adjusted. The rear foot is adjusted by turning the entire foot, see Figure 2-11 Rear Foot.

Mirage M Series User Manual2-11020-100575-02  Rev. 1   (11-2010)
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. 
2.2.5 Basic 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 T
EST 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.

2.2.6 Advanced Optical Alignment
Boresight Alignment Procedure
1. Display the Boresight Test Pattern by pressing the T
EST key on the remote keypad or use the built-in 
keypad and press the soft key that displays Test on the LCD display, then U
P ARROW KEY to cycle to 
Boresight, then Enter, see Figure 2-12 Boresight Pattern.
2. Focus the image on cross-hair pattern I. Evaluate the focus on cross-hair image II and III. If all 3 images 
are in focus, no further action is required. If boresight is required see step 3.
3. If boresight is required, refer to Figure 2-13 Cross-Hair Pattern to understand how the adjustment screws 
on the lens mount affect the corresponding cross-hairs on the test pattern. 
NOTE: The capscrew, (Figure 2-
14) may be under a plastic cap, remove and retain before adjusting.
4. Use a 5mm Allen™ key to loosen the 3 locking setscrews on the lens mount, see Figure 2-14 Screw 
Locations, below. 
NOTE: The setscrews must be backed out several turns, so that they do not contact the 
inner lens mount plate.
FIGURE 2-12 BORESIGHT PATTERN 
						

							Section 2: Installation and Setup
Mirage M Series User Manual2-13020-100575-02  Rev. 1   (11-2010)
5. Fine tune the focus of cross-hair pattern I by adjusting the appropriate capscrew, see Figure 2-14 Screw 
Locations. Adjust until the cross-hair image is in focus with minimal flare.
6. Adjust cross-hair pattern II, by adjusting the appropriate capscrew, see Figure 2-14 Screw Locations. 
Adjust until the cross-hair image is in focus with minimal flare.
7. Adjust cross-hair pattern III, by adjusting the appropriate capscrew, see Figure 2-14 Screw Locations. 
Adjust until the cross-hair image is in focus with minimal flare.
8. Repeat step 5, 6, and 7 as required until all 3 cross-hair patterns are in equal sharp focus. If the boresight is 
acceptable, see step 11. If the boresight does not appear to be converging to an acceptable level of image 
quality or if the lens will not focus over the correct range of throw distances, then the boresight requires 
coarse adjustment, see step 9.
9. The original factory boresight can be recovered approximately by positioning the 3 setscrews, see Figure 
2-14 Screw Locations. Position the setscrews flush with the front face of the lens mount plate and in 
contact with the inner lens mount plate, see below Figure 2-15 Position Setscrew Flush. This may require 
adjusting both setscrews and capscrews.
10. If further action is required. Repeat #2.
11. Lock the setscrews, and re-check the boresight quality. Tighten the setscrew enough to ensure they will not 
shift.

2.2.8 Connecting Communications
Remote Keypads
To control the projector, direct the projector’s IR remote towards the display screen or the projector’s IR sensors. 
Alternatively, connect a wired (tethered) version of the remote to the XLR connector labeled as 
WIRED KEYPAD on the 
projector’s input panel. 
NOTE: The response to a wired keypad must also be enabled in the Communications menu—
see Section 4 Web User Interface for more information.
As an alternative to the projector’s keypad or remote, you may wish to communicate with the projector using a PC or 
other controller. Such a device sends commands and receives feedback via serial links (RS-232 and RS-422RS-422), or 
Ethernet communications to the projector, refer to the Serial Command document provided in the Dealer Section of the 
Christie Website, PN 020-100224-XX.
1.)     Serial Port Connections
RS-232 and RS-422, serial ports available on the projector: You can connect a device with a serial interface, such as a 
computer to either of these connectors (not both) and control the projector remotely by entering specific serial 
communication commands, see Section 3 Operation,COMMUNICATIONS - Submenu and the Serial Command 
document provided in the Dealer Section of the Christie Website, PN 020-100224-XX. 
2.)     Connecting RS-232
Two nine-pin D-sub connectors, labeled RS-232 IN and RS-232 OUT on the input panel, are dedicated to 
serial communication, see Figure 2-17 Connecting RS-232. Using the appropriate serial communication 
cables, connect the controlling source, such as a personal computer to the RS-232 IN connector. Set the 
projector baud rate to match that of the computer. See Section 3 Operation for details on changing the 
projector’s baud rate.
3.)     Connecting RS-422
To control the projector with a computer or other controlling device with RS-422 capability, connect a RS-422 
serial communication cable between the controlling device and the RS-422 port on the projector, see Figure 2-
18 Connecting RS-422. RS-422 is better suited than RS-232 for serial communication over distances greater 
than 50 feet.
Use the RS-422 port only if your device had RS-422 capability - always consult the 
literature provided with your equipment before connecting

Connecting Multiple Projectors
RS-232 NETWORK: To connect multiple projectors in a network with serial communication:
1. Connect the controlling source to the RS-232 IN connector of the first projector in the network.
2. Using another serial communication cable, connect one end to the RS-232 OUT connector and the other 
end to the RS-232 IN connector of the next projector. 
3. Continue this pattern of connection with all projectors in the network. 
NOTE: The last projector in the 
network will only have a connection to the RS-232 IN connector, see Figure 2-19 RS-232 Network.
