AWRcc2 bose wave?

To my excitement I found a Bose wave with 3cd changer at an estate sale. Set it up at home, a cd ejected as soon as powered up in the 1st slot, I pushed it back in. Unfortunately, it now just makes a spinning noise, saying disc error. I can't eject the disc, and suspect the other cd slots have cds in them, but won't eject, the light is lite beside the slot. How do I remove the disc from the number 1 slot?
Thanks for any and all suggestions,
