The device history record (dhr) was reviewed, and no abnormal process conditions were present during the manufacturing of the product that could have led to the reported defect from customer complaint.The dhr review showed that all acceptance criteria inspections per established sampling levels were within acceptable limits during the production process.No samples or photos were received for evaluation therefore the reported condition could not be confirmed, and a root cause could not be determined, however a corrective and preventive action has been initiated to address the reported issue.
