Field service engineer (fse) contacted the customer who had called service saying they had a problem with the detector where the infimed system showed a red triangle as the status.This means the infimed could not communicate with the detector.Fse had user re-sync the processor and the infimed by shutting down the infimed and thales processor system and then talked them through the proper start up sequence for the system; processor first then the infimed system.The detector indication on the infimed then came up as normal and they were able to do a fluoro and spot exposure.Unit was fully functional.This issue indicates that the thales processor and the infimed had either gotten out of sync which could happen if there was a power interruption during procedure (or overnight during table shut down), or the unit couldn't re-calibrate itself.Normally the detector requires a black level calibration every 30 minutes.This would be performed in the back ground unless a patient file was open.If a patient file was open in the acquire mode, the system wouldn't perform a black level calibration until the file was closed.After a long period of inactivity with an open patient file, the thales processor shuts off the communication link.It may be that the user didn't check or didn't notice this detector warning on the initial checkout of the system during start up and may have waited until time to fluoro to check.
