Kunezindlela ezimbili zokubeka amakhebuli optical ngaphezulu:
1. Uhlobo lwezintambo ezilengayo: Okokuqala bopha intambo esigxotsheni ngocingo olulengayo, bese ulenga intambo yokulenga ocingweni olulengayo ngehuku, bese umthwalo wentambo yokubona uthwalwa yintambo elengayo.
2. Uhlobo oluzisekelayo: Kusetshenziswa ikhebula le-optical elizisekelayo.Ikhebula le-optical lisesimweni sika-"8", futhi ingxenye engaphezulu iyintambo ezisekelayo.Umthwalo wekhebula le-optical uthwalwa ucingo oluzisekelayo.
Izidingo zokubeka zimi kanje:
1. Uma ubeka izintambo ezibonakalayo endaweni eyisicaba ngendlela engaphezulu, sebenzisa izingwegwe ukuze uzilengise;beka izintambo zokukhanya ezintabeni noma emithambekeni ewumqansa, futhi usebenzise izindlela zokubopha ukuze ubeke izintambo ezibonakalayo.Isixhumi sekhebula le-optical kufanele sibekwe endaweni yesigxobo esiqondile okulula ukusinakekela, futhi ikhebula le-optical eligodliwe kufanele limiswe esigxotsheni ngobakaki ogodliwe.
2. Intambo yokubona yomgwaqo wepali ongaphezulu iyadingeka ukwenza i-telescopic emise okuka-U njalo ngamabhulokhi ama-3 kuya ku-5, futhi cishe i-15m igcinelwe i-1km ngayinye.
3. Intambo yokukhanya engaphezulu (odongeni) ivikelwe ngepayipi lensimbi, futhi umlomo wombhobho kufanele uvalwe ngodaka olungashi.
4. Izintambo ezibona phezulu kufanele zilengiswe ngezimpawu eziyisixwayiso zekhebula njalo emabhulokhini ama-4 nxazonke nasezigabeni ezikhethekile njengokuwela imigwaqo, ukuwela imifula, namabhuloho okuwela.
5. Ishubhu yokuvikela i-trident kufanele yengezwe ezimpambanweni zomugqa wokulengiswa ongenalutho kanye nentambo yamandla, futhi ukunwetshwa komkhawulo ngamunye akufanele kube ngaphansi kwe-1m.
6. Intambo yesigxobo esiseduze nomgwaqo kufanele isongwe ngenduku ekhipha ukukhanya, ubude obungu-2m.
7. Ukuze kuvinjwe ukugeleza kwentambo yocingo ekulimazeni abantu, intambo yesigxobo ngayinye kufanele ixhunywe ngogesi ocingweni olulengayo, futhi indawo ngayinye yocingo oludonsayo kufanele ifakwe ngocingo oluphansi oludonsa ngocingo.
8. Ikhebula elibona phezulu livamise ukuba ngamamitha amathathu ukusuka phansi.Uma ungena esakhiweni, kufanele udlule emkhonweni ovikelayo wensimbi omise okwe-U odongeni olungaphandle lwesakhiwo, bese welula ubheke phansi noma phezulu.Imbobo yokungena kwekhebula le-optical ngokuvamile ingu-5cm.
