II.Troubleshooting Process
Notes for repairing chair or replacing parts:
①Make sure the power is OFF before tearing down the wires, moving terminals or replacing parts.
②Semiconductors (such as IC and others) are very easy to be damaged by static, so when you touch
the PCB, please make sure your body is grounding (by wearing a girding static ring), or your hands
are touching with earthing grip (household electrical appliances putting to earth, such as fridges,
washers and so on) to release all static of the body.
