Izinyathelo zokuzivikela

1. Qiniseka ukuthi ugwema ukushaja isikhathi eside.Uma ushaja, sicela wenze insimbi isesimweni sokungasebenzi, ungenza isikhathi sokushaja sinciphe, bese ushaja esimweni, inzwa yensimbi ingase ibe ngaphansi komehluko phakathi kweshaja (noma ukuhluka kwendawo yokushaja), ezimweni ezinzima. , ithuluzi lingavela libonisa inani elingalungile noma ngisho nesimo se-alamu.
2. Insimbi esemandleni iyavalwa ngemva kokuvala shaqa okuzenzakalelayo, isikhathi sokushaja esivamile samahora angu-3 kuye kwayi-6 noma ngaphezulu, zama ukungashaji insimbi emahoreni angaphezu kuka-6 ukuze uvikele ingxenye yebhethri yokuphila okusebenzayo kwebhethri. .
3. Ngemuva kokuthi insimbi ishajwe ngokugcwele, isikhathi sokusebenza esiqhubekayo sihlobene nokuvula kanye ne-alamu yepompo.(Ngenxa yokuvula iphampu, i-alamu lapho i-flash, ukudlidliza, umsindo udinga ukusetshenziswa kwamandla okwengeziwe, bekuyisimo se-alamu, isikhathi sokusebenza sehle siye ku-1/2 kuya ku-1/3).
4. Sebenzisa njalo ithuluzi endaweni egqwalayo.
5. Qiniseka ukuthi ugwema ukuthintana nethuluzi.
6. Kutuswa ukunqamula intambo yamandla isikhathi eside, noma ukushaja ibhethri kanye njalo ezinyangeni ezi-1 kuya kwezi-2 ukuze uvikele impilo evamile yebhethri.
7. Uma usebenzisa inqubo, ukuphahlazeka noma awukwazi ukuqalisa, ngemuva kwensimbi ngezansi kwembobo encane, nephezulu yenaliti, ungakwazi.
8. Sicela uqiniseke ukuthi izinkomba zegesi zijwayelekile esimweni se-boot, ngemva kokuqala kwethuluzi ngemva kokuqedwa kokuqaliswa ukuletha indawo yokuthola igesi.
9. Ukusebenzisa umsebenzi wokulondoloza irekhodi, kuhle kakhulu ukuqalisa idivayisi ngemva kokuba ukuqalisa kungaqediwe ngaphambi kokufaka isikhathi sokulinganisa imenyu ukuze uvimbele isikhathi sokufunda isiphithiphithi serekhodi.Uma kungenjalo asikho isidingo sokulungisa isikhathi.
