Ucango lweglasi elawulwa nge-elektroniki
Ibhekisa kumthombo wokukhanya kumzimba womnyango okanye eminye imisebenzi efuna unikezelo lwamandla ukuqalisa, njengokutshintsha kweglasi yombala, ibhendi ekhanyayo kucango lwekhabhathi, umboniso wekristale yolwelo, umboniso we-LED, njl njl. Kuyafuneka ukuba umnyango ungaqhubeka unikezelo lwamandla xa uhamba.Okwangoku, iindlela zonikezelo lwamandla ezisetyenziswa ngokuqhelekileyo kukutsala umbane wekhonkco lokutsalwa kunye nonikezelo lwamandla ebrashi.
