We checked the returned unit and confirmed that the ccd module laser filter lifting.Based on the result, we concluded that it was caused due to the excessive force applied on the ccd module.In addition, we confirmed that the remote control buttons perforated, the light guide cable buckled, the insertion flexible tube (ift) crushed, the biopsy inlet t-piece dirty, and the u/d knob white marking faded/missing; however, they are not the main cause, and/or irrelevant to the alleged complaint.Based on the technical report and/or the risk analysis results, it was evaluated to submit mdr.
