Grille Maintenance and Cleaning
To allow maximum acoustic transparency, the front of the cabinet contains a PVC mesh
grille. Do not apply anything to the surface that may obstruct the holes in the material. To
maintain the brightness of the colors and prolong the life of the grille, periodic cleaning is
necessary. Failure to clean periodically may result in permanent discoloration or staining.
When cleaning, use a mild soapy solution (Dove
®
, Ivory
®
, etc.) and a very soft brush,
moving in a circular motion. Rinse with clean water using normal faucet pressure.
Do not use a power washer�
