Bose&reg; Acoustic Wave&reg; Music System Cream White: Model CD-3000 Original Version aka "I" You can use the remote control to operate most functions of your Acoustic Wave music system. For CD repeat and random play modes, however, you need to use the CD Mode button on the system control panel. If the remote stops operating, or its range seems reduced, try replacing the battery. However, keep in mind that lighting and other room conditions, in addition to battery age, can affect the operating range of an infrared remote control. Note: The remote control feature does not work when operating your Acoustic Wave music system on battery power. This function is disabled to conserve battery power.
