XDB400 letoto la li-transmitters tsa khatello ea ho phatloha li na le setsi sa khatello sa silicon se tsoang kantle ho naha, khetla e sa keneng ho phatloha ha indasteri, le sensor e tšepahalang ea khatello ea piezoresistive. Ba na le potoloho e ikhethileng ea transmitter, ba fetolela lets'oao la millivolt la sensor hore e be motlakase o tloaelehileng le liphetho tsa hajoale. Li-transmitter tsa rona li etsa tlhahlobo ea khomphutha ea othomathike le matšeliso a mocheso, ka hona ho netefatsa ho nepahala. Li ka kopanngoa ka ho toba le lik'homphieutha, lisebelisoa tsa ho laola, kapa lisebelisoa tsa ho bonts'a, tse lumellang ho fetisetsa melaetsa ea nako e telele. Ka kakaretso, letoto la XDB400 le fana ka tekanyo e tsitsitseng, e tšepahalang ea khatello maemong a indasteri, ho kenyeletsoa le libaka tse kotsi.
