7. If you have a level, use it to help you
correctly align the speaker. Tighten the
wall clamp screws with a screwdriver.
This will rotate the wall clamps and
secure the speaker to the wall. Hint-
on the MC65 and MC85 models, tighten
the center screws before tightening the
corners for the most flush fit to your wall.
Do not over tighten the wall clamp
screws Ifigure 14).
8. Carefully reinstall the grille by fitting
it into its recess so that it is just resting
on the frame. Starting with one corner,
go around the speaker and push the grille
into the grille notch a little bit at a time.
Be gentle; the grille may be easily bent
out of shape by rough handling. You
will feel a positive "snap" when it is
fully in place.
Figure 14-Tighten retaining wall clamps
to engage wall. Use a #2 Phillips head
screwdriver or a powered screwdriver.
