We checked the returned unit and confirmed that the objective prism cracked.Based on the result, we concluded that it was caused due to the excessive force applied on the objective prism.In addition, we confirmed that the segment fluid damage, the root brace rubber cracked, the lcb distal cover glass cracked, the operation channel deformed, the operation channel leak, and the light guide fiber bundle (lcb) defective; 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.
