(1) Uma kuyisikrini esidlidlizayo esiyindilinga, isizathu esilula nesivame kakhulu ukuthi ukuthambekela kwesikrini akwanele. Empeleni, ukuthambekela okungu-20 ° kungcono kakhulu. Uma i-engeli yokuthambekela ingaphansi kuka-16 °, izinto eziku-sefa ngeke zihambe kahle noma zizogoqeka phansi;

(2) Ukwehla phakathi kwe-chute yamalahle kanye nobuso besikrini kuncane kakhulu. Uma ukwehla kwamalahle kukhulu, kulapho amandla okushaya asheshayo eba makhulu khona futhi izinga lokuvinjelwa liphezulu. Uma ibanga phakathi kwe-chute kanye nesihlungo lincane kakhulu, ingxenye yamalahle izoqongelela esihlungweni ngoba ayikwazi ukudlula esihlungweni ngokushesha. Uma isihlungo sesinqwabelene, izinga lokuvinjelwa lizoba lincane futhi ikhwalithi yokuzulazula yesihlungo nayo izokhula. Ukwanda kwenani lokudlidliza kwesihlungo kuzonciphisa ngokungenakugwenywa ubukhulu besihlungo, futhi ukwehla kwe-amplitude kuzonciphisa amandla okucubungula esihlungo. Ezimweni ezimbi kakhulu, inqwaba yezinto ezibonakalayo izocindezelwa kuyo yonke indawo yesikrini, okubangela ukuthi isikrini singasebenzi. Ngokuvamile, ukwehla okungu-400-500mm phakathi kwe-chute yokudla kwamalahle kanye nobuso besikrini kufanele kwenziwe;

(3) Ububanzi bethangi lokuphakelayo kufanele bube buphakathi. Uma ligcwele ngokweqile, izinto azikwazi ukusatshalaliswa ngokulinganayo ohlangothini lobubanzi bobuso besikrini, futhi indawo yokuhlunga ayikwazi ukusetshenziswa ngokufanele nangokuphumelelayo;

(4) Isikrini sokubhoboza. Uma ilahle selimanzi, isihlungi sizokwakha i-briquette futhi cishe ngeke kube khona isihlungi. Kulokhu, isikrini sokubhoboza singashintshwa sibe yisikrini sokushisela.
