Iingqwalaselo zokuvezwa kweRF
Esi sixhobo sithobela iFCC mobile radiation exposure limits emiselwe indawo engalawulwayo. Esi sixhobo kufuneka sifakwe kwaye sisebenze kunye nomgama omncinci we-20cm phakathi kweradiyetha kunye nomzimba wakho. Ukuba imodyuli ifakwe kwinginginya ephathwayo, uvavanyo olulodwa lweSAR luyafuneka ukuze kuqinisekiswe ukuthotyelwa kwemithetho yeFCC ephathekayo yokuvezwa kweRF.

Iimpondo
The following antennas have been certified for use with this module; antennas of the same type with equal or lower gain may also be used with this module. The antenna must be:

Ilebhile kunye nolwazi lokuthotyelwa
The final end product must be labeled in a visible area with the following: “Contains FCC ID: 2BRL3-MC26D”. The grantee’s FCC ID can be used only when all FCC compliance requirements are met.

Ulwazi kwiindlela zovavanyo kunye neemfuno zovavanyo ezongezelelweyo
Esi sisasazo sivavanywa kwimeko yokuvezwa kweRF ephathwayo ezimeleyo kwaye nayiphi na indawo ekuyo okanye ngaxeshanye kunye nezinye ii-transmitter okanye ukusetyenziswa okuphathekayo kuya kufuna uhlengahlengiso olwahlukileyo lwe-II okanye isiqinisekiso esitsha.

Uvavanyo olongezelelweyo, iCandelo le-15 Icandelwana B lokuzihlangula

• Umenzi womamkeli unoxanduva lokuthobela inkqubo yomamkeli kunye nemodyuli efakelweyo kunye nazo zonke ezinye iimfuno ezisebenzayo zesixokelelwano ezifana neSahlulo se-15 B.
• INQAKU ELIBALULEKILEYO: Kwimeko apho le miqathango ayinakufezekiswa (ngokomzekeloampulungelelwaniso oluthile lwelaptop okanye indawo edibeneyo nenye isithumeli), emva koko ugunyaziso lweFCC alusathathwa njengelisemthethweni kwaye i-ID yeFCC ayinakusetyenziswa kwimveliso yokugqibela. Kwezi meko, umdibanisi we-OEM uya kuba noxanduva lokuphonononga kwakhona imveliso yokugqibela (kubandakanywa ne-transmitter) kunye nokufumana isigunyaziso seFCC esahlukileyo.

Ulwazi lweManuwali ukuya kuMsebenzisi wokugqibela
Umdibanisi we-OEM kufuneka aqonde ukuba angaboneleli kumsebenzisi wokugqibela malunga nendlela yokufaka okanye ukususa le modyuli yeRF kwincwadana yomsebenzisi yemveliso yokugqibela edibanisa le modyuli.
Incwadi yomsebenzisi wokugqibela iya kubandakanya zonke iinkcukacha ezifunekayo zolawulo/isilumkiso njengoko kubonisiwe kule ncwadana.

OEM / Host uxanduva lomenzi
Abavelisi be-OEM/Host ekugqibeleni banoxanduva lokuthotyelwa kwe-Host and Module. Imveliso yokugqibela kufuneka iphinde ihlolwe ngokuchasene nazo zonke iimfuno ezibalulekileyo zomgaqo weFCC ezifana neFCC iSahlulo se-15 seCandelo B ngaphambi kokuba libekwe kwimarike yase-US. Oku kubandakanya ukuphonononga kwakhona imodyuli yothumelo lokuthotyelwa kweRadio kunye ne-EMF yeemfuno ezibalulekileyo zemithetho yeFCC. Le modyuli akufuneki ibandakanywe kuso nasiphi na esinye isixhobo okanye inkqubo ngaphandle kokuvavanya kwakhona ukuthotyelwa njengesixhobo sosasazo oluninzi kunye nezixhobo ezidityanisiweyo.
