Lesi sisetshenziswa sihloliwe futhi satholwa ukuthi sithobela imikhawulo yedivayisi yedijithali Yekilasi B, ngokususelwe Engxenyeni 15 Yemithetho Ye-FCC futhi sihlangabezana nazo zonke izidingo Ze-Canadian Interference-Causing Equipment Standard ICES-003 yemishini yedijithali. Le mikhawulo iklanyelwe ukuhlinzeka ngokuvikeleka okufanele ekuphazanyisweni okuyingozi ekufakweni kwendawo yokuhlala. Lesi sixhobo sikhiqiza, sisebenzise, futhi singakhipha amandla efrikhwensi yomsakazo futhi, uma ingafakiwe futhi isetshenziswe ngokuhambisana nemiyalelo, ingase ibangele 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 ngesinyathelo esisodwa noma ngaphezulu kwezilandelayo:
- Hlela kabusha noma hambisa uthi olwamukelayo.
- Khulisa ukuhlukana phakathi kwezinto zokusebenza nomamukeli.
- Xhuma okokusebenza endaweni esesekethe ehlukile kuleyo lapho umamukeli axhumeke khona.
- Xhumana nomthengisi noma uchwepheshe werediyo/TV onesipiliyoni ukuze uthole usizo.
- Abasebenzisi abashintsha noma abashintsha umkhiqizo ochazwe kule manuwali ngendlela engagunyazwanga ngokucacile ngabakwa-Thorlabs (uhlangothi olunesibopho sokuthobela imithetho) bangachitha igunya lomsebenzisi lokusebenzisa okokusebenza.
I-Thorlabs GmbH ayinasibopho sanoma yikuphi ukuphazamiseka kukamabonakude womsakazo okubangelwa ukuguqulwa kwalesi sisetshenziswa noma ukufakwa esikhundleni noma okunamathiselwe kwezintambo zokuxhuma nezinto zokusebenza ngaphandle kwalezo ezishiwo yi-Thorlabs. Ukulungiswa kokuphazamiseka okubangelwe ukuguqulwa okungagunyaziwe okunjalo, ukufaka esikhundleni noma okunamathiselwe kuzoba yisibopho somsebenzisi. Ukusetshenziswa kwezintambo ezivikelekile ze-I/O kuyadingeka lapho uxhuma lesi sisetshenziswa kunoma iyiphi kanye nawo wonke amadivaysi okuzithandela noma abamba. Ukwehluleka ukwenza kanjalo kungase kwephule imithetho ye-FCC ne-ICES.
Ukunaka
Izingcingo eziphathwayo, omakhalekhukhwini noma ezinye izithutha zomsakazo akufanele zisetshenziswe ebangeni lamamitha amathathu ale yunithi njengoba amandla kazibuthe kagesi angase adlule amanani aphezulu okuphazamisa avunyelwe ngokuya nge-IEC 61326-1. Lo mkhiqizo uhloliwe futhi watholakala ukuthi uthobela imikhawulo ngokuya nge-IEC 61326-1 ngokusebenzisa izintambo zokuxhuma ezimfushane kunamamitha angu-3 (9.8 feet).
Izitifiketi Nokuthobelana

Ukuze uthole ukwesekwa kobuchwepheshe noma imibuzo yokuthengisa, sicela usivakashele ku- https://www.thorlabs.com/locations.cfm ukuze uthole imininingwane yethu yokuxhumana yakamuva. USA, Canada, and South AmericaThorlabs China chinasales@thorlabs.com Thorlabs 'End of Life' Policy (WEEE) Thorlabs iqinisekisa ukuthobela kwethu isiyalelo se-WEEE (Waste Electrical and Electronic Equipment) Somphakathi WaseYurophu kanye nemithetho kazwelonke ehambisanayo. Ngokuvumelana nalokho, bonke abasebenzisi bokugcina ku-EC bangabuyisela isigaba "sokuphela kwempilo" isigaba se-Annex I sikagesi kanye nezinto zikagesi ezithengiswe ngemva komhla ziyi-13 ku-Agasti 2005 kwa-Thorlabs, ngaphandle kwezindleko zokulahla. Amayunithi afanelekayo amakwe ngelogo ehlukanisiwe “ye-wheelie bin” (bona kwesokudla), adayiselwe futhi okwamanje angaphansi kwenkampani noma isikhungo esingaphakathi kwe-EC, futhi awahlakazwanga noma angcoliswa. Xhumana noThorlabs ukuze uthole ulwazi olwengeziwe. Ukwelapha imfucuza kuwumthwalo wakho. Amayunithi “Ekupheleni Kwempilo” kufanele abuyiselwe e-Thorlabs noma anikezwe inkampani egxile ekubuyiseni udoti. Ungalahli iyunithi emgqonyeni kadoti noma endaweni yokulahla imfucuza yomphakathi. Kuyisibopho sabasebenzisi ukususa yonke idatha eyimfihlo egcinwe kudivayisi
