To service the BV family (Pulsera & Endura) you first must get a service hardware key/dongle from Philips (3rd party service companies can purchase this dongle) with a high enough service level to get into most of the calibration/service software. You must also have Philips BV Scope software to access service if it isn't preloaded on the c-arm. To my knowledge there is no "Administrative Key" however your IT department may have access to Administrative software privilidges which may be where you need to go to clear the error.

The Administration Key is the button on the station that looks like a person. Any time you have an issue like this press that button and it will give you options on what you want to do. It will still hold the images in the queue if you want to resume exporting them later. I hope this helps.
