Chithunzi cha FCC
Zidazi zayesedwa ndipo zapezeka kuti zikugwirizana ndi malire a chipangizo cha digito cha Gulu B, motsatira gawo 15 la malamulo a FCC. Malire awa adapangidwa kuti apereke chitetezo chokwanira ku kusokoneza koyipa pakukhazikitsa nyumba. Chipangizochi chimapanga, chimagwiritsa ntchito komanso chimatha kuwunikira mphamvu zamawayilesi ndipo, ngati sichinayikidwe ndikugwiritsidwa ntchito motsatira malangizo, chikhoza kuyambitsa kusokoneza kwa mawayilesi. Komabe, palibe chitsimikizo kuti kusokoneza sikudzachitika mu unsembe winawake. Ngati chida ichi chikuyambitsa kusokoneza koyipa kwa wailesi kapena kulandila wailesi yakanema, komwe kungadziwike ndikuzimitsa ndi kuyatsa zida, wogwiritsa ntchitoyo akulimbikitsidwa kuyesa kusokoneza ndi chimodzi kapena zingapo mwa izi:
- Yankhanitsaninso kapena sinthani mlongoti wolandira.
- Wonjezerani kulekana pakati pa zida ndi wolandila.
- Lumikizani chipangizocho munjira yosiyana ndi yomwe wolandila amalumikizidwa.
- Funsani wogulitsa kapena wodziwa ntchito pa wailesi/TV kuti akuthandizeni.
Kutsimikizira kutsatiridwa kosalekeza, zosintha zilizonse kapena zosinthidwa zomwe sizinavomerezedwe mwachindunji ndi chipani. Kukhala ndi udindo wotsatira kukhoza kulepheretsa wogwiritsa ntchito kugwiritsa ntchito chipangizochi. (Eksample- gwiritsani ntchito zingwe zotchinga zokha polumikizana ndi kompyuta kapena zida zotumphukira).
Chida ichi chikugwirizana ndi Gawo 15 la Malamulo a FCC.
Kugwira ntchito kumadalira zinthu ziwiri izi:
- Chipangizochi sichikhoza kuyambitsa kusokoneza kovulaza, ndi
- Chipangizochi chiyenera kuvomereza kusokonezedwa kulikonse komwe kulandidwa, kuphatikiza kusokoneza komwe kungayambitse ntchito yosafunikira.
