Pre-Installation
Determine the exact location of the installation on the drop ceiling.
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�
If it helps, create more working space by removing the adjacent
tiles.
c. Place the PCM base plate over the T-frame, between the two marks.
Lightly tighten the T-frame securing screws (which can be inserted
on the inside or outside of the PCM).
d. Mark the location of the PCM base plate on the T-frame to aid in
replacing it in the correct location.
