Izilumkiso
Ukuphatha imiGaqo: Esi sixhobo sisesichengeni sokonakala ngenxa ye-electrostatic discharge (ESD).
Indawo engatshintshiyo ekhululekileyo iyacetyiswa kakhulu. Landela izikhokelo ngokweenkqubo ezifanelekileyo ze-ESD.
Ukhuseleko lweLaser: Imitha ekhutshwa zizixhobo zelaser inokuba yingozi emehlweni abantu. Kuphephe ukuvezwa kwamehlo kwimitha ethe ngqo okanye engathanga ngqo.
