HRAP3 caution?

I’ve enjoyed my stick for the past year without any problems.

However, the stick features a turbo button, and I’d like to know exactly how it works. As I’m sure, you press a button ou’d like to turbo and then tap the turbo button in the upper left corner.

Now the caution: It’s never been applicable to me, but on two separate occations my friends have activated multiple turbos(due to mashng crazy I’m sure) and I was not able to turn it off, having to restart the whole console. Unplugging the stick did not resolve the issue, and spending several minutes trying to undo the trouble didn’t help.

Any advice?
