If it is, press the Mute button on the remote control to unmute the sound. • Make sure the audio input cable is firmly seated in the media center SPEAKER ZONE 1 jack and the multi-pin connector on the other end is firmly seated in the Acoustimass module AUDIO INPUT jack. • Check speaker connections. • Turn the media center off for 60 seconds, then on again, to restore communication between the media 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 disc is placed correctly, label-side up, in the CD tray. • Connect the FM and AM antennas. • Make sure that the power switch on the Acoustimass module is set to ON (I). 39 AM259776_02_V.pdf • April 23, 2002
