7.2.2. Mounting front grille
The front grille is shipped on top of the ampliÄ er inside the box to protect it during shipping. The front grille adheres
to the ampliÄ er with magnets. Hold the front grille with your Ä ngers in each of the side cutouts and slide it gently into
place straight from the front.
NOTE: Always ensure the dust Ä lters behind the detachable front panel are clean to allow maximum
possible airÅ ow. The exterior front panel is held in place by powerful magnets but is easy to detach by
using your Ä ngers in the openings at the each side. To clean the foam Ä lter, detach it from the exterior
front and gently use a vacuum cleaner or gently shake it. Remount with the opposite procedure. Never
operate the ampliÄ er without the dust Ä lter installed.
