Tighten
Tighten screws until the mounting
clamps sufficiently grip the
ceiling. Tighten the screws firmly
to secure the speaker to the
ceiling.
CAUTION
• When tightening the screws, do not
screw too tightly. This may cause
breakage of the mounting clamps and
fracture of the wallboard.
• We recommend using only hand tools
as power screwdrivers may over-
tighten the screws. Should you use a
power screwdriver be certain to select
a very low torque setting to prevent
damage to the speaker or to the
wallboard.
• Make sure that none of the screws are
loose and that there are no gaps
between the speaker and the ceiling.

Attach the speaker grille to the
speaker.
• As several magnets are on the
speaker frame, attach the grille to the
frame directly. When attaching the
grille, make sure that the grille is
attached to the speaker securely to
keep the grille from falling.
CAUTION
• Be very careful when removing the
grille, as it may fall or cause injury.
Also, try to place an equal amount of
pressure on the circumference when
removing the grille. The grille may
bend if too much pressure is placed in
one location.
