The Bose multi-disc CD changer can accept up to four CDs in separate slots. When you eject a disc, they pop out of the slots on the front of the unit. The disc in the Bose base unit is numbered disc 1, with the CD changer unit slots numbered 2 through 4. Each slot on the CD changer has a LED light next to it. When the light is off, there is no disc in the slot.
Press the "CD" button on the remote control to switch to "CD Source" mode.
Press the "CD" button repeatedly until the system selects the disc you want to eject. The system shows the selected disc with a green light next to the CD slot.
Press the "Stop/Eject" button on the remote control twice to eject the selected disc.
