I've gotten this error with a safety shutdown four times now - twice in a row today. It appears to occur if I take off either uphill or downhill too soon after stepping on in balance mode. The 'hill' doesn't need to be at all steep either. Actually, it may not be a safety shutdown. It beeps like one, but doesn't shut off when I step off - I have to shut it off manually. I'll experiment to try to get more information.
