Switch came loose - how do you open up Aeros to fix?

One of the buttons on the Aeros actually just fell out - looks like a simple matter of the nut coming loose inside… has anyone ever had to take one of these apart? Seems like it should be an easy fix if I could feel safe about getting in there to tighten it back up.

Contact support@singularsound.com for help.

I have, thanks, just hoping for an an easy/quick resolution. If i can buy/borrow a replacement for gigs in the meantime, how do i back up the aeros to load songs/settings to replacement? I have backed up the SD card, but not seeing how to back up whatever is only on the Aeros. Thanks!

You would have to move it all to the SD card from the Song List
