English Maintaining Your Lifestyle® 20 Music System Troubleshooting Problem System does not function at all What to do • Make sure the power connector is plugged securely into the music center, the power cord is plugged securely into the Acoustimass® module, the power pack and power cord are plugged securely into operating AC wall outlets, and the module power switch is on. • 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. • If the system is not responding, press STORE, ERASE, and ON/OFF (on the music center) at the same time, to reset the system. No sound • Make sure the audio input cable is firmly seated in the music center SPEAKER ZONE 1 jack and the multi-pin connector on the other end is firmly seated in the Acoustimass module AUDIO INPUT jack. • Make sure the module power switch is in the ON position. • Check the cables connecting the Jewel CubeTM speakers to the Acoustimass module. • Turn the music center off for ten seconds, then on again, to restore 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. • Be sure the CD is placed correctly, label-side up, in the magazine, and the magazine is inserted properly in the music center. • Increase the volume. • Check to see if MUTE is lit on the display.
