So, you power on your OEC 9800 or 9900 C-arm and step away for a moment to let it run its boot-up process. When you return, though, boot-up has frozen and the display on your doghouse (the control housing on top of your central column) reads "Precharge Voltage Error". What happened? And what can you do to resolve the error and get your C-arm booted up for the day's exams?
Don't worry! There's a simple explanation for your problem as well as a simple, do-it-yourself solution that clears most Precharge Voltage Errors.
