main loudspeaker levels and subwoofer level. System volume control is also possible as are some additional

It is recommended that the electronics is checked for any build-up of dust and fluff at least every six months:
• Turn off the subwoofer and disconnect the mains power and signal cables.
• Open the electronics panel (located in the cabinet or remote electronics kit).
• Blow away any dust and fluff by directing low-pressure, clean, compressed air across the circuit boards.
• Close the electronics panel and reattach the mains power and signal cables.
• Power up the subwoofer and check that the appropriate lights are illuminated.
Use a lightly damped cloth to clean the cabinet. Do not use abrasive or alcohol based cleaning materials.
