6. REMOVING THE SPEAKER FOR MAINTENANCE
6.1. Detaching the Front Grille
Turn the front grille counterclockwise to full stop, then lightly
pull it downward.
Tip
The front grille employs a double-locking system.
If the grille cannot be detached when lightly pulled downward,
it likely has not yet been fully rotated back to the detachment
position. In such cases, take care to rotate the grill fully
counterclockwise in order to release the lock.
6.2. Removing the Speaker
Rotate the 3 mounting tab axis screws
counterclockwise. The mounting tabs rise as
they turn, allowing the speaker to be
removed.
Cautions
• When loosening the mounting tab axis
screws, support the speaker by hand to
prevent it from falling.
• Be sure to set the screwdriver's torque for
under 4 kgf·cm.
Failure to do so may cause the Screw cap
and the Mounting tab to fall off on the rear of
ceiling panel.

7. REPAINTING THE SPEAKER
Follow the procedure below when repainting the front grille:
Step 1. Clean the front grille before painting.
Wipe with a soft cloth dampened in a detergent.
Caution
Do not use thinner or other volatile liquids to clean the grille.
Step 2. Spray on a uniform, thin coat of paint.
Cautions
• Avoid painting with a roller or brush, as the grille mesh holes could become clogged with paint.
• Use appropriate spray paints for the front grille (grille and frame) materials.
Grille: Rolled steel plate
Frame: Fire-resistant ABS resin (acrylic paint)
• Be sure to follow the directions indicated on the paint when painting.
Step 3. After the paint has dried, apply another light coat.
Caution
Repeating Step 2, apply two or more light coats of paint.
Application of one thick coat of paint all at once may cause drips or unevenness to show up in the
painted finish, or clog the mesh holes.
