We checked the returned unit and confirmed the ccd module as defective.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 operation channel perforated, the light guide cable buckled, the u/d and the r/l pulley wires worn out, the ccd driver pcb defective, and the insertion flexible tube (ift) bump; 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.
