What to do

• Make sure the power connector is plugged securely into the music center, the Acoustimass

module power cord is plugged securely into the module, and the power pack and power

cord are plugged into operating AC wall outlets.

• Be sure to select a source (CD, AM/FM, etc.).

• Unplug the music center power pack for a minute, then reconnect it. This allows the unit to

reset itself after a power surge or power interruption.

• Make sure the audio input cable is connected to the music center FIXED outputs, the black

connector is fully seated in the music center SYSTEM CONTROL 1 jack, and the multi-pin

connector is firmly seated in the Acoustimass module jack.

• Turn the music center off for ten seconds, then on again, to reestablish communication

between the music center and the speakers.

• Check the connections for any external components. Make sure to select the correct

source for the desired input.

• Check the speaker connections.

• Be sure the CD is placed correctly, label-side up, in the music center, and the cover is

closed.

• Increase the volume.

• Check to see if MUTE is lit in the display. Press the MUTE button on the remote to unmute

the sound.

• Disconnect any headphones.

• Connect the FM and AM antennas.

• Make sure that the center cube cable is connected at both ends.

• Select STEREO+CENTER (3-speaker) or SURROUND (5-speaker) mode.

• In STEREO+CENTER mode, press SURROUND

• Press and hold the STEREO+CENTER (3-speaker) mode key for 10 seconds to restore the

factory preset center volume setting.

• Select SURROUND (5-speaker) mode.

• Press SURROUND

• Make sure the video sound source is stereo and surround-encoded, and the component

used (TV, VCR, DVD or laserdisc player) is stereo.

• In SURROUND mode, press SURROUND

• Make sure that the left and right front speakers are connected to the front speaker jacks

and the left and right surround speakers are connected to the surround speaker jacks.

• Press and hold the SURROUND (5-speaker) mode key for 10 seconds to restore the factory

preset surround volume setting.

• Check batteries and their polarity (+ and –).

• Operate the remote control closer to the music center.

• Make sure the remote control house code matches the music center code. Follow steps 4-7

on page 24 to match the house code settings.

• Change the house code setting to prevent signals from conflicting with another nearby

Lifestyle

system. See page 24 for instructions on setting the house code.
