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.
