Cleaning the housing and the mainframe
When cleaning either the mainframe or the housing of your instrument, 
only use a dry and very soft cotton tissue on the surfaces and the numeric 
pad. 
Never open the instruments as they can be damaged. Opening the 
instruments puts you in danger of receiving an electrical shock from your 
device, and renders your warranty void.
