Zen Muse chattering / ratteling

[digitalphat]

I just updated the firmware of my DJI phantom 2, which I bought on ebay and now it seems the Zen Muse is broken. Since I am not sure about this I uploaded a video about the issue. Maybe I am just doing something completely wrong and its a normal behaviour. If you have any idea I would really appreciate if you could help me.

Thanks, R*
