Mysterious button
![userHead](/forum/images/userhead.png)
There is a button right next to the dual USB jack. I cannot find anything about it.
On the docs page under Inputs and Outputs, there is a image of pins and stuff, but you cannot enlarge it. Maybe I have to old of eyes, but I cannot make out much of anything there.
