He iti te hiko e pau ana i te pūrere, ā, kāore e taea te whiwhi raraunga tuku iho mai i te pokapū raraunga.

Me tuku ake e te DTU ngā raraunga me te tomo ki te aratau hononga i mua i te tuku raraunga e te pokapū.

I muri i te korenga o te whakawhitiwhiti raraunga, ka uru aunoa a MDN311 ki te aratau PSM hei pupuri i te iti o te whakamahinga hiko i te wā tūtatari.

Ka tautoko a MDN311 i te mahi hōtaka tuhinga. Ka taea e ngā kaiwhakamahi te whakarite i ngā kōnae tuhinga mā te pūmanawa whirihoranga whakairoiro o te taputapu, kia kore ai e hiahiatia he kaiwhakahaere tāpiri mō ngā tono kei te papaanga, ā, kia kore ai e whakawhirinaki ki te tūāpapa raraunga hei tuku tohutohu kohikohi hei whakatutuki i te hononga tika ki te taputapu. Ka kohikohi tika, ka kaha hoki a MDN311 i ngā raraunga mai i te taputapu, ka ripoata atu ki te tūāpapa.

Whakaritenga Hōputu Mōkihi Raraunga Ngāwari

Mōkihi rēhita ritenga:Ka taea e ngā kaiwhakamahi te whirihora noa i ngā ihirangi o te mōkihi raraunga ka tukuna ina honoa tuatahitia a MDN311 ki te pokapū raraunga.

Mōkihi ngakau ritenga:Ka taea e ngā kaiwhakamahi te whirihora noa i ngā ihirangi o te mōkihi ngākau i tukuna e MDN311 ki te pokapū raraunga.

Mōkihi pane ritenga:Ka taea e te kaiwhakamahi te whirihora i ngā ihirangi motuhake i mua i te tukunga o te mōkihi raraunga e te DTU ki te pokapū raraunga hei wehewehe i te momo raraunga, i te kāwai rānei.
