Preparing the Installation Location
Suspended Ceiling
1.
Power down all attached devices before proceeding.
2.
Ensure that there is sufficient clearance above the ceiling tile for the unit to be installed.
3.
Cut a hole for the speaker. Use the provided cutout template to outline the hole to be cut in the ceiling tile as described below.
a.
Remove the ceiling tile.
b.
To find the center of the tile, use a tape measure to measure the space between two opposite corners, and mark the half-way
point.
c.
Position the center hole of the cutout template directly over the center of the tile that you marked in step 3b.
d.
Using the provided cutout template, trace a circle around the cutout template.
e.
Cut out the circle traced on the ceiling tile.
f.
Replace the tile in the ceiling.
4.
Attach two V-rails and one C-ring across the tile above the hole cut in step
3, as shown below
:
a.
Assemble two V-rail half sections as follows: fit the tab of one end into the slot of the other end, then open the V-rail until it locks
together (see figure 2). Repeat this procedure for the other V-rail.
Figure 1.
Assembling the V-rails
b.
Remove a ceiling tile adjacent to the tile with the hole.
c.
Place both assembled V-rails on the cut ceiling tile and position them equally on either side of the hole. The ends of the V-rails go
over the ceiling grid.
d.
Position the C-ring assembly on the two V-rails so that the C-ring is centered over the hole, as shown below.
