Izixwayiso

Izinyathelo Zokuphatha:Le divayisi isengozini yokulimala ngenxa ye-electrostatic discharge (ESD).

Indawo ekhululekile enganyakazi inconywa kakhulu.Landela imihlahlandlela ngokwezinqubo ezifanele ze-ESD.

Ukuphepha kwe-Laser:Imisebe ekhishwa ngelaser ingaba yingozi emehlweni abantu.Gwema ukuchayeka kweso emisebeni eqondile noma engaqondile.
