ISITATIMENDE SE-FCC

Isexwayiso se-FCC:
Noma yiziphi Izinguquko noma ukuguqulwa okungagunyazwanga ngokucacile yinhlangano enesibopho sokuthobela imithetho kungasusa igunya lomsebenzisi lokusebenzisa okokusebenza. Le divayisi ithobela ingxenye 15 yemithetho ye-FCC. Ukusebenza kungaphansi kwemibandela emibili elandelayo:

1. Le divayisi ingase ingabangeli ukuphazamiseka okuyingozi, futhi
2. Lolu cingo kufanele lwamukele noma yikuphi ukuphazamiseka okutholiwe, okuhlanganisa ukuphazamiseka okungase kubangele ukusebenza okungafuneki.

ISAZISO ESIBALULEKILE:

Qaphela: Lesi sisetshenziswa sihloliwe futhi satholwa ukuthi sithobela imikhawulo yedivayisi yedijithali Yekilasi B, ngokuvumelana nengxenye 15 Yemithetho ye-FCC. Le mikhawulo iklanyelwe ukuhlinzeka ngokuvikeleka okufanele ekuphazanyisweni okuyingozi ekufakweni kwendawo yokuhlala. Lesi sixhobo sikhiqiza, sisebenzise futhi singakhipha amandla efrikhwensi yomsakazo futhi, uma singafakiwe futhi sisetshenziswa ngokuhambisana nemiyalelo, singadala ukuphazamiseka okuyingozi ezokuxhumana ngomsakazo. Nokho, asikho isiqinisekiso sokuthi ukuphazamiseka ngeke kwenzeke ekufakweni okuthile. Uma le mishini ikwenza
kubangele ukuphazamiseka okuyingozi emsakazweni noma ekwamukelweni kwethelevishini, okunganqunywa ngokucisha nokuvula imishini, umsebenzisi uyakhuthazwa ukuthi azame ukulungisa ukuphazamiseka ngesinye sezinyathelo ezilandelayo noma eziningi:

• Hlela kabusha noma hambisa uthi olwamukelayo.
• Khulisa ukuhlukana phakathi kwesisetshenziswa nomamukeli.
• Xhuma okokusebenza endaweni yokuphuma kuyisekethe ehlukile kuleyo lapho umamukeli axhumeke khona.
• Xhumana nomthengisi noma uchwepheshe werediyo/TV onesipiliyoni ukuze uthole usizo.

Isitatimende Sokuchayeka Kwemisebe ye-FCC: Lokhu okokusebenza kuthobelana nemikhawulo yokuchayeka emisebeni ye-FCC ebekwe endaweni engalawuleki. Lo mshini kufanele ufakwe futhi usebenze ngebanga elincane elingama-20cm phakathi kwerediyetha nomzimba wakho
