INSTALLATION

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.

10 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.
