What to do
• Make sure the power connector is inserted securely into the media center, the power cord
is inserted securely into the Acoustimass® module, and the power pack and power cord
are fully plugged into operating AC wall outlets.
• Be sure to press a source button (CD/DVD, AM/FM, etc.) on the L1FESTYLE® remote
control.
• Unplug the media center power supply for 60 seconds, then reconnect it.
This allows the unit to reset itself after a power surge or power interruption.
• 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.
• Check the connections for any external components. Make sure that you have pressed the
correct remote button for the source you want to hear.
• For CD or DVD play, be sure the disc is placed correctly, label-side up, in the disc tray.
• Connect the FM and AM antennas.
• Make sure that the power switch on the Acoustimass module is set to ON (I).
• Make sure that the audio input cable:
- Connector is firmly seated in the media center Main Speaker jack.
- Multi-pin connector at the other end is firmly seated in the Acoustimass module
AUDIO INPUT jack.
• Check connections between the cube speakers and the module.
• Turn off the media center for 60 seconds, then on again, to restore communication
between the media center and the speakers.
• Make sure that the power switch on the Acoustimass module is set to ON (I).
• Contact Bose® Customer Service to determine if and how other electrical components in
the room may be creating unwanted signals, and the possible remedies.
• Make sure the center speaker cable is connected at both ends.
• Select 3- or 5-speaker mode.
• Decrease the Center Channel setting.
