CP2000-M Motorized Auxiliary Lens Mount (M-MALM) Installation Instruction Sheet The main purpose of the M-MALM is to provide unattended auxiliary lens insertion into the light path to change the aspect ratio of the projected image from flat 1.85:1 to scope 2.39:1. The following instructions outline how to install and optimize the M-MALM for the CP2000-M/MR projectors. This attachment is typically used for scope displays in side-masking theaters. Once installed and adjusted the M-MALM can move the 1.25x anamorphic lens (38-809054-xx) or the 1.26x wide converter lens (108-281101-xx) using various projector controls, through the CDP or web user interface, or as part of an automation (requires 3rd-party automation controller). Allow approximately 30 minutes for installation and setup. NOTE: Refer to 3rd party documentation for instructions on how to use the M-MALM with a 3D system.
SAFETY PRECAUTIONS DANGER
ELECTRICAL SHOCK HAZARD! Always turn off, disconnect, and disengage all power sources to the projector before servicing. Failure to comply results in death or serious injury. Only Christie accredited service technicians are permitted to open any enclosure on the projector and only if the AC power has been fully disconnected. Failure to comply could result in minor or moderate injury.
KITS REQUIRED • CP2000-M Motorized Auxiliary Lens Mount (M-MALM): 119-101101-xx • Optional Wide Converter Lens (WLS): 108-281101-xx Or: • Optional Anamorphic Lens: 38-809054-xx NOTE: Anamorphic or wide converter lenses are purchased separately.
TOOLS REQUIRED • 5mm Allen™ key

INSTRUCTIONS NOTES: 1) When using the M-MALM the primary lens can only use 30% horizontal offset and 50% vertical offset. 2) A minimum 1.6:1 lens throw distance is required.
MOUNTING M-MALM 1. Install the 4 mounting posts into the bottom of the projector. 2. Line the mounting points of the M-MALM frame up with the points on the bottom of the projector. Tighten the 4 mounting bolts to secure the frame to the projector (Figure 1-1). 3. Plug the M-MALM assembly into the serial connection on the PCM interface panel (Figure 1-1).

M-MALM Z-ADJUSTMENT 1. Use a 5mm Allen™ key to loosen the 4 bolts underneath the front of the M-MALM frame (Figure 1-2). 2. Slide the plate back and forth to make adjustments to the Z-axis. NOTE: The out position of the MMALM assembly is on the right-side of the projector when standing behind the projector facing the projection screen. 3. Z-adjustment is typically done to set nominal spacing between the wide converter lens and the prime lens. Use the steps outlined below when adjusting the mechanical distance between the converter lens and prime lens. a. 1.3-1.75:1: Mechanical distance from the converter lens to the prime lens should be set to 34.6mm/1.36” (near) - 29mm/1.14” (far). b. 1.75-2.4:1: Mechanical distance from the converter lens to the prime lens should be set to 25mm/0.98”.

c. 2.4 - 3.9:1: Mechanical distance from the converter lens to the prime lens should be set to 20mm/0.78”.
M-MALM X-ADJUSTMENT X-adjustment of the M-MALM is controlled either through the CDP Configuration>Auxiliary Lens>Adj Lens In-Pos/Adj Lens Out-Pos menu or through the web user interface Advanced>Lens menu. For more information, refer to the CP2000-M/MR User Manual (020-100123-xx).
M-MALM Y-ADJUSTMENT 1. Loosen the 1/4” screws (x2) on the back of the lens clamp and manually turn the adjusting bolt (Figure 1-2) on the front to make adjustments to the Y-axis. 2. Once the setting is accurate tighten the 1/4” screws.
FIGURE 1-2 M-MALM ADJUSTMENT
M-MALM HORIZONTAL BORESIGHT ADJUSTMENTS (LEFT/RIGHT) 1. If the image appears well-focused on the left edge, but not on the right, then the boresight needs to be adjusted. 2. Loosen the left and right setscrews for each adjusting bolt (Figure 1-2). 3. Adjust the left and right adjustment bolts using a 5mm Allen™ key. Adjust as necessary to direct or “aim” the lens toward the edge of the image, which is focused too close to the lens. When the left and right appear equally blurry, re-focus on the left-side of the screen. 4. Adjust horizontal offset to re-center the image on the screen. 5. Repeat Steps 3 and 4 until both sides of the image are well focused. 6. Tighten the setscrews to lock the adjustment bolts in place. Check boresight again.

M-MALM VERTICAL BORESIGHT ADJUSTMENT (TOP/BOTTOM) 1. When left/right boresight is complete, focus the image at the top edge of the screen. 2. Adjust the vertical boresight bolt using a 5mm Allen™ key (Figure 1-2). Adjust as necessary to direct or “aim” the lens toward the edge of the image, which is focused too close to the lens. When both top and bottom appear equally blurry, re-focus at the top of the screen. 3. Refocus: Although all sides of the image should now be in focus, the center of the image will be slightly blurry at this point. Refocus at center of image. The goal is to have uniform focus on all sides. 4. Tighten the setscrew to lock the adjustment bolt in place and check boresight again.
