二.故障检修流程图 Troubleshooting Process
在修理或者替换零配件过程中注意下面几点：
A. 在拆卸连线，移动连接器，或者替换部件前一定要断开电源线插头。
B. 因为半导体（像集成电路，或者其它的）很容易被静电损坏，所以当要触摸 PCB 前，请确保你的身
体和大地有连线（佩带静电手环），或可以将手放在地端，以释放身体上所带的静电。
Notes for repairing chair or replacing parts
A. Make sure the power is off when you tear down the wires, move terminals or replacing parts.
B. The semiconductors( like IC or something else) will easily be damaged by static.
So you touch the PCB before, please make sure your body is connected with the ground.
