2. chipangizo ichi ayenera kuvomereza kusokonezedwa kulikonse analandira, kuphatikizapo kusokonezedwa kungayambitse ntchito osafunika.

Chotumizira ichi sichiyenera kukhala pamalo amodzi kapena kugwira ntchito limodzi ndi mlongoti wina uliwonse kapena chopatsira.

ZINDIKIRANI: 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.

Ndemanga ya FCC Radiation Exposure:

Chipangizochi chimagwirizana ndi malire a FCC okhudzana ndi kukhudzidwa kwa ma radiation omwe akhazikitsidwa kumalo osalamulirika. Zidazi ziyenera kuyikidwa ndikugwiritsidwa ntchito ndi mtunda wochepera 20cm pakati pa radiator ndi thupi lanu.
