STEP 4 INSTALLATION OF THE PROJECTOR ATTACHMENT PLATE
4.1 Place the attachment plate over the bottom of the projector (See Fig. 6)
and align the holes of the plate with the threaded fittings on the projector case.
4.2 Install the three M4 x 12mm long screws provided. Fasten these securely but
DO NOT overtighten. (See Fig. 7)
4.3 Install the longer, M4 x 30 mm flat head screw into the indicated hole. (It goes
into the recessed fitting in the plastic housing).

NOTE: PLEASE LOOK OVER THE EXACT MANNER IN WHICH THE
POSITIONING ASSEMBLY AND THE ATTACHMENT PLATE GO
TOGETHER SO THAT YOU WILL BE ABLE TO REASSEMBLE THEM
WHEN YOU HANG THE PROJECTOR.
3.1 Using 9/16 ” box wrench, remove the nut from the lower knuckle
(vertical position) and slide the center and upper knuckle assembly apart
from the bottom knuckle which is part of the
attachment plate. (See Fig. 5)
SPECIAL NOTE TO INSTALLERS: In some instances the relationship of
the location of the projection screen to the exact position of the ceiling
mounting bracket makes it desirable to have the centerline of the lens at
the center of the mounting bracket. If you find it necessary to have the
lens at the centerline of the mount, remove the lo wer element of the
positioning knuckle from its original position and re-mount it in the D
shaped hole in the mounting plate located in the area over the lens. This
will align the centerline of the lens with the center of the mounting
bracket. The positioning knuckle assembly can easily compensate for the
slight loss of static balance of the mounted projector.
