5.Center the grille on the loudspeaker baffle. The magnets hold the grille in place. Note: You can rotate the grille as necessary within the constraints of the tether.

Rotating the grille beyond the constraints of the tether with excessive force can break the tether.

6.Optional - A drill template and four M4 Plastite® screws are provided with the grille assembly for screw-mounted grille installation if desired.

To provide clearance for the grille screws, use a 3.4 mm drill bit to drill through the grill mounting holes in the loudspeaker baffle shown as item a (Figure 23) and into the ceiling material.

Use a 4.8 mm drill bit and the supplied template to drill the holes in the grille.
