Consider the following:

• The vertical and horizontal offsets of the projector from the proposed location.

• The projector dimensions relative to the image target.

NOTE: See the projector manual for details.

Installation

Step 1 — Mark the Frame and Cut the Ceiling Tile.

a.At the location for the projector, identify the ceiling tile and T-frame where the PCM will be installed.

b.Remove the predetermined ceiling tile and mark the maximum and minimum throw distances of the projector on the T-frame (see figure 2).

TIP: Mark the screen direction on the back of the tile to help with orientation of the tile when replacing it after cutting.

c.Place the PCM base plate over the T-frame, between the two marks. Lightly tighten the T-frame securing screws.

d.Mark the location of the PCM base plate on the T-frame to aid in replacing it in the correct location.

e.Measure the distances X and Y (see figure 2) from the inner vertical section of the front and left T-frame runners to the center of the Pipe Adapter Plate.
