Bose manufactures 5-disc CD changers sold under the company's Acoustic Wave brand name. The self-contained music system includes an FM radio tuner, built-in stereo speakers and disc slots on the front of the component for five CDs. The Acoustic Wave is designed to display an error message if it cannot detect the presence of a CD in the compact disc player. If you see the "No Disc" message but know positively that there is a CD in the Bose, try troubleshooting the component to fix the problem.
Insert a CD label-side up into each of the five slots on the front of the Bose to verify that none of the trays are empty. Attempting to play CD1 when there is only a disc in CD3, for example, will result in a "No Disc" message.
Press the button corresponding to the CD you wish to play. The trays are numbered vertically 1-5.
Push the "Aux 1" button so the Aux indicator light illuminates on the Bose Acoustic Wave. This button must be pressed if the unit is set to CD changer mode.
Eject and clean each CD by wiping in a zigzag motion with a clean, lint-free cloth. Dampen the cloth with a few drops of ammonia to remove grease or oily fingerprints. If the Bose CD laser lens is unable to read the data on the disc, a 'No Disc" error message may be displayed.
