Kulephera kugwira ntchito mosavutachithandizo

zizindikiro za vuto la kulephera kugwira ntchito bwino	Wonongekachifukwa
Palibe chizindikiro pa wolandila ndi wotumiza	Palibe mphamvu pa chotumizira, mphamvu yolandirira siilumikizidwa bwino
Wolandila alibe chizindikiro cha RF	Ma band a ma frequency olandila ndi otumizira ndi osiyana kapena osakhala pamlingo woyenera
Pali chizindikiro cha ma wailesi, koma palibe chizindikiro cha mawu	Maikolofoni yotumizira si yolumikizidwa kapena cholumikizira cha wolandila chili chovuta kwambirikwambiri
	Kulephera kwa kayendedwe ka mawu kowongolera phokoso
	Kukhazikitsa mawonekedwe chete
Phokoso lakumbuyo la chizindikiro cha mawu ndi lalikulu kwambiri	Kupatuka kwa ma frequency otumizira ndi kochepa kwambiri, landirani zotulutsa zamagetsi Mulingo wake ndi wotsika, Kapena pali chizindikiro chosokoneza
Kusokoneza chizindikiro cha mawu	Tumizaniterkusintha kwa ma frequency deviation ndikokwera kwambirilalikulu, mphamvu yamagetsi yolandirira ndi yayikulu kwambiri
Mtunda wogwiritsidwa ntchito ndi waufupi, chizindikiro sichikhazikika	Mphamvu yosinthira ma transmitter ndi yochepa, ndipo chokokera cha wolandila ndi chakuya kwambiri. Kukhazikitsa kolakwika kwa antenna yolandila komanso kusokoneza kwamphamvu kwa batri mozungulira.
