1) Nco ntsoov kom tsis txhob them lub sijhawm ntev. Lub sijhawm them nyiaj yuav txuas ntxiv mus, thiab lub ntsuas qhov ntsuas yuav cuam tshuam los ntawm qhov sib txawv ntawm lub charger (lossis them ib puag ncig qhov sib txawv) thaum lub ntsuas ntsuas qhib. Nyob rau hauv feem ntau cov mob hnyav, nws yuav txawm tshwm sim ntsuas qhov yuam kev tso saib lossis lub tswb.
2) Lub sij hawm them nqi ib txwm yog 3 mus rau 6 teev los yog li ntawd, sim tsis txhob them cov cuab yeej hauv 6 teev lossis ntau dua los tiv thaiv lub neej zoo ntawm lub roj teeb.
3) Lub ntsuas hluav taws xob tuaj yeem ua haujlwm rau 12 teev lossis yog li ntawd tom qab them tag nrho (tshwj tsis yog lub tswb lub xeev, vim tias lub flash thaum lub tswb nrov, kev vibration, suab xav tau lub zog ntxiv. Lub sijhawm ua haujlwm txo qis rau 1/2 txog 1/3 thaum tuav lub tswb. xwm txheej).
4) Nco ntsoov tsis txhob siv cov cuab yeej hauv ib puag ncig corrosive
5) Nco ntsoov kom tsis txhob sib cuag nrog cov cuab yeej dej.
6) Nws yuav tsum tau muab tshem tawm lub hwj chim cable, thiab them txhua 2-3 lub hlis, txhawm rau tiv thaiv lub roj teeb lub neej thaum tsis siv ntev.
7) Yog tias lub ntsuas hluav taws xob sib tsoo lossis tsis tuaj yeem qhib tau, koj tuaj yeem tshem tawm cov hlua hluav taws xob, tom qab ntawd ntsaws cov hlua hluav taws xob los daws qhov teeb meem sib tsoo.
8) Xyuas kom tseeb tias cov ntsuas roj yog qhov qub thaum qhib lub ntsuas.
9) Yog tias koj xav tau nyeem cov ntaub ntawv ceeb toom, nws qhov zoo tshaj plaws nkag mus rau hauv cov ntawv qhia zaub mov kom raug lub sijhawm ua ntej qhov pib tsis tiav kom tsis txhob muaj kev ntxhov siab thaum nyeem cov ntaub ntawv.
10) Thov siv cov software calibration tseem ceeb yog tias xav tau, vim tias qhov ntsuas ib leeg tsis tuaj yeem ntsuas.
Nco tseg: Tag nrho cov ntawv txuas yog xaiv tau, uas yog raws li cov neeg siv khoom xav tau sib txuam. Cov kev xaiv no xav tau tus nqi ntxiv.
