Meanings switches Jetson TX1

I want to know the meaning of each button on JTx1.
I have 4 buttons and I know only the first button (power switch), whats is the meaning Recovery Switch,Reset Switch and Volume Down Switch

Reset basically yanks the power while held down…think of it as a warm reboot (bad for the file system if running normally).

Recovery switch, if held down while bring up or resetting power, puts the Jetson in recovery mode. The micro-B USB connector changes from being a root HUB of a running system to instead becoming a special USB device understood by flash software. Nothing will happen to the Jetson unless flash software runs…recovery mode in itself does nothing.

I haven’t used the volume down switch, I assume if you run audio over HDMI that this brings down volume…but since I’ve never used this it’s just a guess.
