1, the belt of information, tools with all, do not try to save trouble。
My headache is that when giving on-site technical support, I ask the other party to refer to some information and some items, and then the other party says "I forgot to bring", "I don't have this information", "you tell me about the information content".。
Oh, my God. I'm not an announcer。Besides, even if I did read several pages, how much would I remember from across the phone？

2, encounter problems, fix or do not get, to record the fault phenomenon, test process, test each link of the elevator state changes。
Done: After summing up some experience, you can ask the leader to correct the wrong content of the understanding, which is your own accumulation;
If you can't get it done: Feedback detailed records to the technical department will help solve the problem as soon as possible。
I am very disgusted with the feedback question when the sentence "xx bad", I have to ask details everywhere, which saves the brains of the people on the scene, and wastes the time on both sides of the factory and the scene。

3, found product problems to timely and accurate feedback to the quality control department。
After all, the elevator is assembled by countless parts, and the problem is controlled well, it is not easy to have problems。
