There is a cd stuck in the system how do i get it out

In the manual page 55 it says

"Turn off the unit.

• Unplug the Acoustimass module power cord from the outlet for one minute, then reconnect

it. This allows the unit to reset itself.
• Before powering on, press and hold Eject on the media center"

Here is the manual in case you need to reference it.

this was answered in another blog http://www.ehow.com/how_7661625_troubleshooting-bose-av-321-ii.html

This solution is from the troubleshooting section of the manual:

• Follow these steps:
1. Turn off the unit.
2. Unplug the Acoustimass module power cord from the outlet for 60 seconds, then reconnect it. This
allows the unit to reset itself.
3. Before powering on, press and hold Eject on the media center.

Hope this info may help you!
