Pali njira ziwiri zoyalira zingwe zowonekera pamwamba:
1. Mtundu wa waya wolendewera: Choyamba mangani chingwe pamtengo ndi waya wolendewera, kenaka mupachike chingwe cha kuwala pa waya wolendewera ndi mbedza, ndipo katundu wa chingwe cha kuwala amanyamulidwa ndi waya wolendewera.
2. Mtundu wodzithandizira: Chingwe chothandizira chokha chimagwiritsidwa ntchito.Chingwe chowala chili mu mawonekedwe a "8", ndipo kumtunda kwake ndi waya wodzithandizira.Katundu wa chingwe cha optical amanyamulidwa ndi waya wodzithandizira.
Zofunikira pakuyika ndi izi:
1. Mukayala zingwe zowonekera pamalo athyathyathya m'mwamba, gwiritsani ntchito mbedza kuzipachika;ikani zingwe zowala m'mapiri kapena m'malo otsetsereka, ndipo gwiritsani ntchito njira zomangira kuti muyale zingwe zowunikira.Chojambulira chingwe cha kuwala chiyenera kukhala pamalo owongoka omwe ndi osavuta kusamalira, ndipo chingwe chosungirako chiyenera kukhazikitsidwa pamtengo ndi bracket yosungidwa.
2. Chingwe chowonekera chamsewu wopita kumtunda chimafunika kupanga chopindika chowoneka ngati U-telescopic pa midadada 3 mpaka 5 iliyonse, ndipo pafupifupi 15m imasungidwa pa 1km iliyonse.
3. Chingwe choyang'ana pamwamba (khoma) chimatetezedwa ndi chitoliro chachitsulo, ndipo mphuno iyenera kutsekedwa ndi matope osayaka moto.
4. Zingwe zapamtunda ziyenera kupachikidwa ndi zikwangwani zochenjeza pamabuloko anayi aliwonse mozungulira komanso m'zigawo zapadera monga kuwoloka misewu, kuwoloka mitsinje, ndi milatho.
5. Chubu chachitetezo cha trident chiyenera kuwonjezeredwa pamzere wa chingwe choyimitsidwa chopanda kanthu ndi chingwe chamagetsi, ndipo kutalika kwa mapeto aliwonse sikuyenera kukhala osachepera 1m.
6. Chingwe chamtengo pafupi ndi msewu chiyenera kukulungidwa ndi ndodo yotulutsa kuwala, ndi kutalika kwa 2m.
7. Pofuna kupewa kuti mawaya oyimitsidwa asavulaze anthu, chingwe chilichonse chiyenera kulumikizidwa ndi magetsi ku waya woyimitsidwa, ndipo malo aliwonse a waya wokoka ayenera kuikidwa ndi waya wokoka pansi.
8. Chingwe chapamwamba chapamwamba chimakhala 3m kuchokera pansi.Polowa m'nyumbayi, iyenera kudutsa muzitsulo zotetezera za U-zofanana ndi U pakhoma lakunja la nyumbayo, ndikupitirira pansi kapena pamwamba.Kabowo ka khomo lolowera chingwe cha kuwala nthawi zambiri ndi 5cm.
