So, you power on your OEC 9800 or 9900 C-arm and step away for a moment to let it run the boot-up process.

And what can you do to resolve the error and get your C-arm up and running 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.
