Only original parts should be used to replaced any part marked with symbol .Any other component substitution (other than original type), may increase risk of fire or electrical shock hazard.4Service NoteCautions during Inspection and Repair1. Keep in mind the safety warningsThe safety instructions are shown as the labels or printings on the exterior, the inside chassis or the parts, etc. Refer to the instructions when proceeding with inspection or repair.2. Use only the specified parts for replacementThe selected parts are used at critical area to reduce fire hazard or electrical shock. So when replacing these parts where designaged with marks or marks on the schematic diagram or the parts list, ensure to use only the same parts. 3. Ensure to dress back the AC (Mains) cord to the original positionIf for some reason, the AC cord is moved or partially disassembled, ensure to re-route or assemble back to the original position. The AC cord area is protected and secured by tubing and insulation materials for the sake of safety, so that no loose wire will touch and cause fire hazard and electrical shock.4. Check for safety aspects after inspection or repairEnsure all parts, such as screws or wires, removed during inspection or repair are secured back to the original positions, and check visually for any anomaly. Also check for any electrical leakage or resistance to maintain the safety.
