Make sure the RotoLock clamps are in
the full clockwise position so that all the
clamps are tucked within the cutout
border. Insert the speaker into the hole
in the ceiling.
Note: The maximum clamp thickness is
1-1/4" (32mm)
Tighten the four screws on the front of
the baffle. The RotoLock clamps will
rotate into position automatically and
begin clamping. When you notice
resistance on the four screws, the
speaker has been clamped successfully.
The flange is designed to flex and
conform to any small imperfections in
the ceiling surface. The screws should
not be tightened so far that the flange
bows out.

At this step in the installation the
transformer tap selector can be set.
Depending on your installation you may
wait to set the volume of each speaker
until the system is completely installed.
After the speaker is installed, and
transformer tap adjustments are made,
the grille can be installed. Insert about
half of the grille into the groove at the
edge of the speaker. Gently fit the
remaining half of the grill into the
speaker by working your hands around
the speaker fitting the grille into the
groove as you go along.
Note: The torque applied to the
mounting screws can be adjusted for
proper grille fit.

The included C-bracket and tile support rails should be used in all
suspended ceiling installations. The C-bracket and tile support rails can
also be used in installations when the speakers are mounted into
material that will not support their weight.
Insert the two tile support rails and C-bracket through the hole you
have cut. placing them as shown. Using the two screws that are
supplied, screw the C-bracket to the tile support rails as shown.
After the C-bracket and tile support rails are installed follow Step 2
through Step 7 in the standard installation instructions.
