Ibiranga ibicuruzwa:
Urusaku rwiza kandi ruto, ruri munsi cyangwa rungana na 60db.
Ibyuma bihanitse, ibyuma bisobanutse neza.
Igihe kirekire cya bateri, kuzigama ingufu.
Feri ya electromagnetic, ihagarare iyo urekuye, na feri mugihe amashanyarazi azimye.
Umutekano mwinshi, hamwe nibikorwa bitandukanye.
Guhitamo kubisabwa, ibisobanuro bitandukanye.
Uru ruhererekane rwamashanyarazi rugizwe na DC ihoraho ya magneti yasunitswe na moteri kandi itandukanye. Ifite ibiranga radiyo ntoya ihinduka hamwe na sensibilité yo hejuru.
