Insert the speaker into the hole. Loosen four
screws approximately one turn counter-
clockwise. It will allow the clamps to open easily.
Evenly tighten each of the four mounting screws
clockwise using a Philips screwdriver. (At this
time, these four mounting clamps open in the
ceiling. These opened clamps will press the
ceiling board and the speaker together to secure
the speaker.) 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.
HINT
• Tighten the screws in order of
opposite sides rather than
clockwise or counter-clockwise
direction (such as right and left,
then top and bottom).

Adjust the angle of the tweeter.
• Gently press the outer edge of the tweeter housing
toward the listening position.
• This tweeter movable angle is about 15 q in multiple
directions.
CAUTION
• When adjusting the tweeter, do not rotate it. This may cause
the breakage of the tweeter.

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.
