We checked the returned unit and confirmed that the balloon feeder/return tube clogged.Based on the result, we concluded that it was caused due to the insufficient reprocessing at the facility.In addition, we confirmed that the us connector body broken, the operation channel buckled, and the remote control buttons cut; however, they are not the main cause, and/or irrelevant to the alleged complaint.Based on the technical report ""hr-rpt-0630(air/water & jet water channels)"" and/or the risk analysis results, it was evaluated to submit mdr.
