resultant 12 mm-diameter holes. The front grille can be
mounted directly to the ceiling panel using the supplied
mounting bracket.

6.3.2. Front grille installation
Step 1. Before mounting the front grille directly to the ceiling panel,
Step 1-1. Attach the four supplied stud holders to
the mounting bracket using the four
supplied tapping screws.
Step 1-2. Detach the stud receptacles from the
main speaker unit and attach them to
the stud holders.
Step 2. Mount the mounting bracket to the
ceiling panel. (Follow Steps 1.– 4. on P.
4 "Flush Wall or Ceiling Mounting.")
Step 3. Attach the masking tapes to the ceiling
panel as shown on the right to prevent
the white ceiling panel from being seen
through the front grille meshes.
Step 4. Align the front grille with the speaker so
that the four stud screws align with the
unit's corresponding stud receptacles,
then push the grille onto the speaker.
