Kwinkqubo yokudaya, i-R etyheli ngqo inokusabela ngokweekhemikhali kunye nezinto zefayibha ukwenza ichibi lombala elizinzileyo, ukuze kufezekiswe ukudaya kweempahla, ulusu kunye nezinye izinto.
Umbala oMthubi ngqo Rineempawu ezilungileyo zokudaya, ezinokwenza izinto ezidayiweyo zibonise imibala eqaqambileyo nehlala ixesha elide. Ukongeza, ikwanokunyibilika kakuhle kwaye isasazeke kakuhle, kulula ukuyisasaza ngokulinganayo emanzini okanye kwezinye izinyibilikisi, kwaye kulula ukuyidaya. I-R etyheli ethe tye ikwanokuxhathisa ukukhanya, ukumelana namanzi kunye nokungqubana, ukuze izinto ezidayiweyo zingabi lula ukubuna nokuguguleka ngexesha lokusetyenziswa. Nangona kunjalo, i-R etyheli ethe tye ikwanazo neengozi ezithile zokhuseleko kwinkqubo yokusetyenziswa. Ngenxa yokuba inesakhiwo se-azo, phantsi kweemeko ezithile inokukhupha iigesi ezinobuthi, nto leyo ebangela umonakalo emzimbeni womntu nakwindalo esingqongileyo.
