Idizayini Eshumekiwe ye-Boardcon
Enza ngendlela oyifisayo isistimu eshumekiwe ngokusekelwe ku Umbono Wakho
1. Isingeniso
1.1. Mayelana nale Manuwali
Le manuwali ihloselwe ukunikeza umsebenzisi i-overview yebhodi nezinzuzo, izici ezicacisiwe eziphelele, kanye nezinqubo zokumisa. Iqukethe nolwazi olubalulekile lokuphepha futhi.
1.2. Impendulo kanye nesibuyekezo sale Manuwali
Ukuze sisize amakhasimende ethu azuze ngokugcwele ngemikhiqizo yethu, sihlala senza izinsiza ezengeziwe nezibuyekeziwe zitholakale ku-Boardcon webindawo ((www.boardcon.com , www.armdesigner.com)).
Lokhu kufaka phakathi amamanuwali, amanothi ohlelo lokusebenza, isib sokuhlelaamples, kanye nesoftware ebuyekeziwe nehardware. Ngena ngezikhathi ezithile ukuze ubone ukuthi yini entsha!
Uma sibeka phambili umsebenzi kulezi zinsiza ezibuyekeziwe, impendulo evela kumakhasimende iyithonya lokuqala, Uma unemibuzo, ukuphawula, noma ukukhathazeka mayelana nomkhiqizo noma iphrojekthi yakho, sicela ungangabazi ukusithinta ku- support@armdesigner.com.
1.3. Iwaranti enomkhawulo
I-Boardcon iqinisekisa ukuthi lo mkhiqizo ungabi nasici kokubalulekile nokusebenza isikhathi esingangonyaka owodwa kusukela ngedethi yokuthenga. Ngalesi sikhathi sewaranti i-Boardcon izolungisa noma ishintshe iyunithi enesici ngokuhambisana nenqubo elandelayo:
Ikhophi ye-invoyisi yoqobo kufanele ifakwe lapho kubuyiselwa iyunithi enesici ku-Boardcon. Lesi siqinisekiso esikhawulelwe asibandakanyi umonakalo obangelwa ukukhanya noma okunye ukusetshenziswa kwamandla, ukusetshenziswa kabi, ukuhlukumeza, izimo ezingavamile zokusebenza, noma imizamo yokushintsha noma ukulungisa umsebenzi womkhiqizo.
Lesi siqinisekiso sikhawulelwe ekulungiseni noma ekushintshweni kweyunithi enesici. Akukho mcimbi lapho i-Boardcon izobophezeleka khona noma ibe nesibopho sanoma yikuphi ukulahlekelwa noma umonakalo, okuhlanganisa kodwa okungagcini nje kunoma iyiphi inzuzo elahlekile, umonakalo wengozi noma umphumela, ukulahlekelwa kwebhizinisi, noma izinzuzo ezilindelekile ezivela ngenxa yokusebenzisa noma ukungakwazi ukusebenzisa lo mkhiqizo.
Ukulungisa okwenziwa ngemva kokuphela kwesikhathi sewaranti kungaphansi kwenkokhiso yokulungisa kanye nezindleko zokubuyisela umkhumbi. Sicela uxhumane ne-Boardcon ukuze uhlele noma iyiphi isevisi yokulungisa futhi uthole ulwazi lwenkokhelo yokulungisa.
