1. Ukushintsha Izinga Lokuqonda
1.1 Kuyini Ukushintshwa Kwezinga?
Ukushintsha ileveli idivayisi esetshenziselwa ukuthola ubukhona noma ukungabikho koketshezi noma impahla eyinqwaba endaweni ethile. Ngokungafani nezinzwa zeleveli eqhubekayo, ezihlinzeka ngesilinganiso sesikhathi sangempela sobude boketshezi, amaswishi eleveli ngokuvamile asebenza njengezinkomba zeleveli yephoyinti. Bacupha i-alamu, bavule iphampu, noma bathumele isignali kusistimu yokulawula lapho okokusebenza kufinyelela ubude obusethiwe.
Ukushintsha kwamazinga kubalulekile ekuqinisekiseni ukuphepha nokusebenza kahle. Zisiza ukugcina amazinga oketshezi afanele, zivikele ukuchichima noma ukoma komshini wamaphampu, futhi zihlanganise namasistimu azenzakalelayo ukuze kugcinwe ukuzinza kwenqubo. Inhloso eyinhloko yokushintshwa kweleveli akukona ukulinganisa okuqhubekayo kodwa ukutholwa okunembile ezindaweni ezibucayi, ngokuvamile okwanele ezisetshenziswa eziningi zezimboni nezasekhaya.
