Isitatimende se-US FCC
Le divayisi ithobela Ingxenye 15 Yemithetho ye-FCC. Ukusebenza kungaphansi kwemibandela emibili elandelayo:
- Le divayisi ingase ingabangeli ukuphazamiseka okuyingozi.
- Lolu cingo kufanele lwamukele noma yikuphi ukuphazamiseka okutholiwe, okuhlanganisa ukuphazamiseka okungase kubangele ukusebenza okungafuneki.
Lesi sisetshenziswa sihloliwe futhi satholwa ukuthi sithobela imikhawulo yedivayisi yedijithali Yekilasi B, ngokuvumelana neNgxenye 15 yeMithetho ye-FCC. Le mikhawulo iklanyelwe ukuhlinzeka ngokuvikeleka okufanele ekuphazanyisweni okuyingozi ekufakweni kwendawo yokuhlala. Lesi sixhobo sikhiqiza, sisebenzise, futhi singakhipha amandla efrikhwensi yomsakazo futhi, uma singafakiwe futhi sisetshenziswa ngokuhambisana nemiyalelo, singadala ukuphazamiseka okuyingozi ezokuxhumana ngomsakazo. Nokho, asikho isiqinisekiso sokuthi ukuphazamiseka ngeke kwenzeke ekufakweni okuthile. Uma lesi sisetshenziswa sidala ukuphazamiseka okuyingozi emsakazweni noma kumabonakude, okunganqunywa ngokucisha nokuvula okokusebenza, umsebenzisi uyakhuthazwa ukuthi azame ukulungisa ukuphazamiseka ngesinye salezi zinyathelo ezilandelayo:
- Hlela kabusha noma hambisa uthi olwamukelayo.
- Khulisa ukuhlukana phakathi kwesisetshenziswa nomamukeli.
- Xhuma okokusebenza endaweni esesekethe ehlukile kuleyo lapho umamukeli axhumeke khona.
- Xhumana nomthengisi noma uchwepheshe werediyo/TV onesipiliyoni ukuze uthole usizo.
Noma yiziphi izinguquko noma ukuguqulwa okungagunyazwanga ngokucacile yinhlangano enesibopho sokuthobela imithetho kungasusa igunya lomsebenzisi lokusebenzisa okokusebenza.
Lokhu okokusebenza kuthobelana nemikhawulo yokuchayeka emisebeni ye-FCC RF ebekwe endaweni engalawuleki. Lolu cingo kanye nothi lwayo akumele kubekwe endaweni eyodwa noma kusebenze ngokuhambisana nanoma yiluphi olunye uthi noma isidlulisi. Ama-antenna asetshenziselwa lesi sithumeli kufanele afakwe ukuze anikeze ibanga lokuhlukanisa okungenani elingama-20 cm kubo bonke abantu futhi akumele abekwe ndawonye noma asebenze ngokuhlangana nanoma iyiphi enye i-antenna noma isidlulisi.
OEM Integration Imiyalo
- This device is intended only for OEM integrators under the following conditions.
- The module can be used for installation on another host.
- I-antenna kufanele ifakwe ngendlela yokuthi u-20 cm ugcinwe phakathi kwe-antenna nabasebenzisi, futhi imojula yokudlulisa akumele ihlanganiswe nanoma yisiphi esinye isidluliseli noma uthi.
- The module shall be used only with the integral antenna(s) that have been originally tested and certified with this module. As long as 3 conditions above are met, further transmitter tests will not be required.
- Kodwa-ke, isihlanganisi se-OEM sisenomthwalo wemfanelo wokuhlola umkhiqizo wabo wokugcina nganoma iyiphi imfuneko eyengeziwe yokuhambisana nale mojula efakiwe (ngokwesibonelo.ample, digital device emission, PC peripheral requirements, etc)
Isaziso:
Esimeni lapho le mibandela ingenakufinyelelwa khona (ngokwesiboneloample, certain laptop configurations or colocation with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid, and the FCC ID of the module cannot be used on the final product. In these and circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
Qeda Ukulebula Komkhiqizo
Le moduli yesidluliseli igunyazwe kuphela ukusetshenziswa kumadivayisi lapho i-antenna ingafakwa ngendlela yokuthi u-20 cm angagcinwa phakathi kwe-antenna nomsebenzisi. Umkhiqizo wokugcina kufanele ulebulwe endaweni ebonakalayo ngokulandelayo:
- “Contains FCC ID: SAK-ESP32S3
- Host Marketing Name(HMN) – Smart Smoke/CO Alarm
Isitatimende se-IC
Le divayisi ithobelana nama-RSS akhululiwe elayisensi ye-Industrial Canada. Ukusebenza kungaphansi kwemibandela emibili elandelayo:
• Lolu cingo angeke lubangele ukuphazamiseka, futhi
• Lolu cingo kufanele lwamukele noma yikuphi ukuphazamiseka, okuhlanganisa ukuphazamiseka okungase kubangele ukusebenza okungafunwa kocingo.
Isitatimende Sokuchayeka Kwemisebe
This equipment complies with IC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 cm between the radiator & your
umzimba.
RSS247 Isigaba 6.4 (5)
Idivayisi ingakumisa ngokuzenzakalela ukuhanjiswa uma kungabikho imininingwane yokudlulisa noma ukwehluleka kokusebenza. Qaphela ukuthi lokhu akuhloselwe ukwenqabela ukuhanjiswa kokulawulwa noma ukusayinda imininingwane noma ukusetshenziswa kwamakhodi aphindaphindwayo lapho kudingeka khona ubuchwepheshe.
Le divayisi ihloselwe kuphela izihlanganisi ze-OEM ngaphansi kwalezi zimo ezilandelayo: (Ngokusetshenziswa kwedivayisi yemojuli)
- I-antenna kufanele ifakwe ngendlela yokuthi i-20 cm igcinwe phakathi kwe-antenna nabasebenzisi, futhi
- Imojula yokudlulisa kungenzeka ingabi ndawonye nanoma yisiphi esinye isidluliseli noma uthi.
Inqobo nje uma izimo ezi-2 ezingenhla zihlangatshezwana nazo, ezinye izivivinyo zama-transmitter ngeke zidingeke. Kodwa-ke, isihlanganisi se-OEM sisenomthwalo wemfanelo wokuhlola umkhiqizo wabo wokugcina nganoma yiziphi izimfuneko zokuthobela ezengeziwe ezidingekayo ngale mojuli efakiwe.
ISAZISO ESIBALULEKILE:
Esimeni lapho le mibandela ingahlangabezwana nayo (ngokwesiboneloample, ukulungiselelwa okuthile kwekhompuyutha ephathekayo noma ukufakwa kwesinye isidluliseli), ukugunyazwa kwe-Canada akusabhekwa njengokuvumelekile, futhi i-IC ID ayikwazi ukusetshenziswa emkhiqizweni wokugcina. Kulezi zimo, isihlanganisi se-OEM sizoba nesibopho sokuhlola kabusha umkhiqizo wokugcina (okuhlanganisa nesidlulisi) kanye nokuthola ukugunyazwa okuhlukile kwe-Canada.
Le moduli yesidluliseli igunyazwe kuphela ukusetshenziswa kumadivayisi lapho i-antenna ingafakwa ngendlela yokuthi u-20 cm angagcinwa phakathi kwe-antenna nomsebenzisi. Umkhiqizo wokugcina kufanele ulebulwe endaweni ebonakalayo ngokulandelayo:
- “Contains IC: 7145-ESP32S3”.
- Host Marketing Name(HMN) – Smart Smoke/CO Alarm
Manual Information To the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product that integrates this module.
