FCC Chirevo
Midziyo iyi yakaedzwa uye yakawanikwa inoenderana nemiganhu yeKirasi B yedhijitari mudziyo, zvichienderana nechikamu chegumi neshanu chemitemo yeFCC. Iyi miganho yakagadzirirwa kupa dziviriro inonzwisisika kubva mukukanganisa kunokuvadza mukuiswa kwekugara. Mudziyo uyu unogadzira, unoshandisa uye unogona kuvheneka redhiyo frequency simba uye, kana isina kuiswa uye kushandiswa zvinoenderana nemirairo, inogona kukonzera kukanganisa kunokanganisa kufambiswa kweredhiyo. Nekudaro, hapana vimbiso yekuti kukanganisa hakuzoitika mune imwe yekumisikidza. Kana mudziyo uyu ukakonzera kukanganisa kunokuvadza redhiyo kana terevhizheni, iyo inogona kutariswa nekudzima uye nekubatidza mudziyo, mushandisi anokurudzirwa kuyedza kugadzirisa kukanganiswa neimwe kana anopfuura eanotevera matanho:
- Reorrent kana kutamisa antenna inogamuchira.
- Wedzera kupatsanurwa pakati pemidziyo nemugamuchiri.
- Batanidza midziyo mune yekubuda padunhu rakasiyana neiyo iyo inotambirwa yakabatana.
- Bvunza mutengesi kana nyanzvi yeredhiyo/TV ine ruzivo kuti ubatsirwe.
Kuvimbisa kuenderera mberi kwekuteerera, chero shanduko kana shanduko dzisina kubvumidzwa nebato. Kuva nemhosva yekuteerera kunogona kukanganisa mvumo yemushandisi yekushandisa mudziyo uyu. (Eksample- shandisa tambo dzakavharidzirwa chete kana uchinge wabatana nekombuta kana midziyo yeparutivi).
Ichi chishandiso chinoenderana neChikamu 15 cheFCC Mitemo.
Kushanda kunoenderana nemamiriro maviri anotevera:
- Ichi chishandiso chinogona kusakonzera kukanganisa kunokuvadza, uye
- Muchina uyu unofanirwa kugamuchira chero kukanganisa kunowanikwa, kusanganisira kukanganisa kunogona kukonzera kushanda kwausingadi.
FCC Radiation Exposure Statement:
Midziyo iyi inoenderana neFCC Radiation exposure limits yakatemerwa nharaunda isingadzoreki. Mudziyo uyu unofanirwa kuisirwa uye kushanda nedikidiki chinhambwe 20cm pakati pe radiator nemuviri wako.
