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.
