Izindlela zokusebenza zezifiso zezindawo zemvelo zokwenza ukulungiswa kwesiliva esikhathini esidlule, kanye nokubonisa ukulungiswa kwesiliva esikhathini esidlule. Kukhona isikhuba kanye nesikhumba sokwenza. Uma ukulungiswa kwesiliva okufanele kube kwenziwe, isikhuba singathintwa ngokwesokudla, isikhuba singathinta isikhuba sokwenza ukuhamba phezulu nokulandelana, futhi indawo yeesikhuba ingathintwa ngosikhumba sokwenza, ukuze kube khona isikhala phakathi kweesikhuba nesikrini, futhi ngaphezu kwalokho, iimeko zesikhala ezikhona kwi-sikrini zingathintwa. Yenza umsebenzi ophansi wezinto ezihambayo ezinzima.
