Stallation thiab kev khiav hauj lwm
1 Ua ntej siv lub zog tawm suab, sim ntsuas theem seb puas yuav nyob rau ntawm theem nruab nrog. Koj yuav tsum tau kho theem cov tswv yim nkag mus rau nws.
2Cov lus piav qhia qib tsis tuaj yeem siab dhau. Cia li kom txhua qhov TV teeb tsa theem ntawm 60 ~ 75dBμV. Tig ATT pob qhov rooj mus kho cov qib theem.
3Thaum xob quaj, kom tsis txhob muaj xob laim, koj yuav tsum tua lub fais fab. Lub suab nrov siv sab hauv tsev nkaus xwb thiab zam kom tsis txhob cuam tshuam nrog dampor siab kub.
4Keep lub hwj huam muab voltage ntawm ntau yam. Tsis muaj hluav taws xob tsawg yuav ua rau daim duab tsis zoo.
