H6: the cori tablet p/n rob10027 s/n (b)(6) used for treatment was not made available to the designated complaint unit for evaluation thus, visual inspection and functional testing could not be performed.A relationship between the reported event and the device could not be established as the product was not returned.A review of manufacturing and service records indicate the device met all specifications upon release into distribution.A complaint history review for similar reported/confirmed complaints has identified prior events.Although the reported problem was not confirmed, factors that may have contributed to the reported symptom may have been associated with a cable/connector electrical component failure, esd (electro static discharge) interference that causes the tablet to shut off to prevent current overload, or firmware.Although no further containment or corrective action is recommended or required at this time, all complaints are monitored and trended through post market surveillance activities.If the product associated with this event is returned at a future date, this evaluation will be reopened for investigation.
