Maintenance
You can clean the panel of subwoofer and casing by wiping with a soft cloth. Never clean with alcohol, benzene, paint thinner, or other
such solvents, as these may cause discoloration.

Never use contact restoring agents to restore electrical connections, as these may cause the subwoofer to fail. Agents that include oil
may in addition lead to deformation of the plastic.
