User manual OPTOMA BX-AL133B

[. . . ] Due to the large distortion and also the increased non-uniformity of image brightness (hot spotting) at very low throw ratios you may wish to consider a curved screen in such cases to help compensate for these artifacts. Image/Lens Shift Horizontal lens/image shift other than fine adjustment is not recommended due to keystoning that can be introduced by the UH480. However, note that with vertical lens shift the UH480 should be tilted to face the approximate center of the screen to make any residual pincushion distortion symmetric at the top and bottom of the image. A NOTE ON YOUR SCREEN FORMAT The BX-AL133B system works very well with a 2. 35:1 aspect ratio screen. [. . . ] Therefore, the ideal ceiling mount location will be shifted by the AKPro 2" (50mm) toward the left side of the screen from the ceiling mount location indicated by your projector's instructions. If your projector ceiling mount is already installed and you do not wish to move it (or similarly move the screen in the opposite direction) due to a shift by the AKPro system, then you can make fine horizontal shift adjustments to your projector (if available) combined with turning the projector (only as necessary) during final setup to compensate for the shift. Some small amount of image distortion (horizontal keystoning) may result but in most cases this will not be noticeable since the image edges will typically be masked by the screen borders. WARNING! Use extreme caution and appropriate hardware when installing heavy objects to a ceiling. Periodically check all fasteners and connection hardware to be sure they are not coming loose. Improper installation may lead to an increased risk of your equipment becoming unstable and possibly injuring someone.

Consult the Attachment Plate Diagram for plate orientation, hole positions and required screws and spacers for your projector model. Insert and tighten each screw through an appropriate silver washer and lock washer, the designated holes in the Attachment Plate, then through any required spacers and finally into the projector ceiling mount holes. Using the included gold hex key, install the six 7/8" socket head screws each through a 3/8" aluminum spacer and into the six threaded holes from the ceiling side of the attachment plate. Insure that the RPA mount head is secure (see instructions included with the RPA mount) and oriented properly relative to the 7/8" socket head screw heads so that the mounted projector will face the screen. Use two people to lift and position the projection assembly so that the heads of each of the 7/8" socket head screws rest within the matching final location of the RPA mount head. At this point the silver 3/8" spacers should be between the Attachment Plate and the RPA mount head. The projection assembly may be lowered to allow the 7/8" screw heads to rest on the RPA mount. However, a first person should continue to guide the projection assembly while and a second person uses the gold assembly wrench to tighten the 7/8" screws. When tightening these screws, do so in a pattern of incrementally driving each screw a little more into the attachment plate so that at any time the projection assembly is resting on as many screw heads as possible until all are tightened. If the lens must be removed for any length of time it is recommended that a similar weight be suspended from the front of the attachment kit to balance the weight of the projector. This will minimize unusual stresses on the ceiling mount system. Optoma BX-AL133B User Manual and Installation Guide, Version 1. 0, copyright Nov, 2008, all rights reserved, Panamorph Inc. [. . . ] Adjust and tighten the nuts on the Plate Hook Assemblies to make the Chains tight but without raising the front of the Attachment Plate. You may wish to turn the projector on to ensure the image remains properly oriented to the screen during this step. At this point proceed to the appropriate lens/transport mounting step.
