| Urwego rwa IPC rugaragaza urwego rwubuziranenge bwa buri bwoko bwibibaho byacapwe, kandi bamwe mubakora ibikoresho bya elegitoronike bafite ubushobozi bwo gukora IPC ibicuruzwa byambere nuwa kabiri. Mugihe gito, ntihashobora kubaho itandukaniro rigaragara, ariko mugihe, ibibazo byubuziranenge bwibicuruzwa bigaragara cyane. Niba ibicuruzwa byawe ari mubyiciro byinganda kandi ukaba wibanda ku giciro kirekire cyibicuruzwa, nyamuneka wemeze guhitamo urwego rwo hejuru.
