Nga whakaritenga
I a koe i roto i te hohipera, i etahi atu whare tiaki hauora, tirohia nga here mo te whakamahi waea pūkoro. Whakawetohia te tauranga pūkoro, waea pūkoro ranei, he tairongo pea nga taputapu rongoa ka kore e mahi i te nuinga o te waa na te wawaotanga o te hiko RF.
Whakawetohia te tauranga pūkoro, waea pūkoro ranei i mua i te eke ki runga waka rererangi. Me mohio kua whakawetohia. Ko te mahi o nga taputapu ahokore i roto i te waka rererangi ka aukati kia kore e pokanoa ki nga punaha korero. Ko te wareware ki te whakaaro nui ki enei tohutohu ka pa ki te haumarutanga o te rere, ka whakaparahako ranei i nga mahi ture a-rohe, e rua ranei. Kaua e whakahaere i te tauranga pūkoro, waea pūkoro ranei i te aroaro o te hau mura ahi ranei. Whakawetohia te tauranga pūkoro ina tata koe ki nga teihana penehīni, putunga wahie, tipu matū, kei hea ranei nga mahi pupuhi. Ko te mahi o nga taputapu hiko i roto i nga hau karekau e paahu ka noho he morearea haumaru.
Ka whiwhi, ka tuku i to tauranga waea pūkoro ranei i te hiko auau reo irirangi i te wa e ka ana. Ka puta te pokanoa RF mena ka whakamahia tata ki nga pouaka whakaata, reo irirangi, rorohiko me etahi atu taputapu hiko.
Ko te haumaru huarahi te tuatahi! Kaua e whakamahi i te tauranga waea-a-ringa, waea pūkoro ranei i te wa e peia ana he waka, mena ka mau ki roto i te pukoro mo te mahi kore-ringa. I mua i te waea waea me te tauranga pupuri-ringa, waea pūkoro ranei, tuhia te waka.
Karekau e taea te hono atu i nga waahi katoa nga kapeka pūkoro GSM, nga waea pūkoro ranei e mahi ana i runga i nga tohu auau reo irirangi me nga whatunga waea pūkoro i nga ahuatanga katoa, ina koa me te utu pūkoro, he kaari SIM muhu ranei. I a koe i roto i tenei ahuatanga me te hiahia awhina ohorere, maharatia ki te whakamahi waea ohorere. Kia taea ai te waea, te tiki waea ranei, me whakakaina te tauranga waea, waea pūkoro ranei, me te waahi ratonga me te kaha o te tohu waea pūkoro. Ko etahi o nga whatunga kare e whakaae ki te waea ohorere mena kei te whakamahia etahi ratonga whatunga me etahi ahuatanga waea (hei tauira, nga mahi raka, waea whakapumau me etahi atu). Me whakakorehia e koe aua ahuatanga i mua i to waea ohorere. Ano, ko etahi o nga whatunga e hiahia ana kia whakauruhia he kaari SIM whaimana ki roto i te tauranga pūkoro, waea pūkoro ranei.
