I'm assuming you know how it works? press eject, the loaded trays light up and you select the tray to unload.

Apparently if you hold down the eject button for 3 secs i think (hold longer if needed) it automatically ejects all loaded discs one at a time. this may work if button 1 is faulty?

Please post any detailed manual eject instruction you learn of and i'll add this post to the audio thread.
