Ref.Id: (b)(4).The digitaldiagnost c90 is a stationary x-ray system for general radiographic purposes.As an option, a portable digital flat panel detector (model "skyplate") can be used for image capture.The local field service engineer (fse) went on site, checked the detector and tried several times to calibrate with no success.The affected detector need to be replaced.A new detector was sent to the site and was installed.Finally, the system meets the specification for the performed service and is returned to use.The customer confirms that the detector was dropped by accident (use error).Risk estimation revealed acceptable risk per risk benefit analysis, because actually, there is no feasible technical solution for this kind of ¿use error¿.This issue is further monitored and trended.
