RJ12 ikurikirana umuyoboro wubwoko bwabanyamaguru, ibikoresho byo kugenzura imirasire yumurongo

Ibisobanuro bigufi:

RJ12 abanyamaguru hamwe nibikoresho bipakurura ibikoresho bya radio ni ibikoresho byo kugenzura amaradiyo abanyamaguru n'imizigo.Ifite ibiranga ibyiyumvo bihanitse, intera nini yo gutahura nigihe gito cyo gusubiza, kandi irashobora gutahura imirasire yumuriro, kubika amakuru byikora nibindi bikorwa.Sisitemu yo guhitamo isura idahwitse, ihujwe na sisitemu yo guhitamo byikora, irashobora kumenya abantu bakekwa mukarere kateganijwe.Irashobora gukoreshwa ahantu hatandukanye h’inzira zitumizwa no kohereza hanze, nkumupaka wubutaka, ikibuga cyindege, gariyamoshi, gari ya moshi, amaduka, nibindi.
