• Make sure the Acoustimass ® module power cord is inserted securely into the AC (mains) power outlet

and into the power connector on the Acoustimass module.

• Be sure to press a source button (CD.DVD, CBL.SAT, etc.) on the 3o2.1 ® remote.

• Unplug the power cord for 60 seconds, then plug it in again. This allows the unit to reset itself after a

power surge or power interruption.

• For a 230-240V system (used typically in Europe), make sure the power switch on the Acoustimass

module is turned on ( I ).

• For a dual voltage 3.2.1 system only, make sure the voltage setting is correct for your region. If it is set

to 115V, the system may not operate in a 230V region.

CAUTION: Do not change the voltage switch from 230V to 115V unless you are certain it is appropriate for

the power supply in your location.

• Increase the volume.

• Check to see if MUTE is lit on the display. If it is, press the Mute button on the remote control to unmute

the sound.

• Be sure that you have pressed the correct source button (CD.DVD, CBL.SAT, etc.) on the 3.2.1 remote.

• Check the audio connections for the component you want to play.

• Connect the FM and AM antennas.

• Make sure that the cable between the Acoustimass module and the media center is connected securely.

• Check connections between the speakers and the Acoustimass module.

• Turn off the media center for 60 seconds, then on again, to restore communication between the media

center and the speakers.

• Make sure speaker cables are not damaged and the connections are secure.

• Reduce the volume level on the external device playing through the 3o2.1 system speakers.

Try plugging your system into a different AC outlet.

Check to see if your media center and its audio input cable are within 3 ft (1 m) of any other electronic or

electrical device. Some examples are a TV, cable box, VCR, wireless internet router, dimmer switches,

blinking lights, or microwaves.

Move the media center farther away and notice if the humming still occurs.
