Muyezo wolondola umafunika zenizeni-mamita a RMS pa katundu wamagetsi, wokhala ndi miyeso yachindunji yomwe nthawi zonse imakonda kuposa mawerengero a nameplate

Kukhathamiritsa kumaphatikiza kufananitsa katundu (kumanja-zida zakumanja), kugwiritsa ntchito bwino zinthu (matekinoloje amakono), ndi nthawi yogwiritsira ntchito (kukonza{1}}ntchito zojambula bwino)

Kukwanilitsa kumatsatira njira yokhazikika: zolemba zoyambira → kusanthula mawonekedwe → kuzindikiritsa mwayi → kugawa kwapang'onopang'ono → kuyang'anira mosalekeza
