Front grille
Unlock
Pull lightly.
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.
9.2. Removing the Speaker
Rotate the 3 mounting tab axis screws counterclockwise. The mounting tabs rise as they turn, allowing the
speaker to be removed.
Caution
When loosening the mounting tab axis screws, support the speaker by hand to prevent it from falling.
