It has the same built in Diagnostic screen as the jetBooks.
To enter the diagnostics screen:
Reset the device. Then hold down three buttons. They are: "on/off" "zoom" and "menu". When you see the jetBook screen let go of "on.off". Keep holding the "zoom" and "menu" keys until you see a 16 item screen. It's tricky, so it may take a couple of tries.
Then you can restore the JBL to factory defaults.
After that is done reset the JBL.
The "reset" is the reset button on the back.
