48、ings 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 replacement The 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 position If for some reason, the AC cord is moved or partially disassembled, ensure to re- route or assemble back to the origina
