二. Troubleshooting Process
Attention 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 …) to release all static of the body.
