Service Note
Cautions during Inspection and Repair
1. Keep in mind the safety warnings
The 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 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 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 repair
Ensure 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.
