3  Operation 

 
Handle with appropriate precautions and be done in accordance with strict ESD control. 
 
It is the user choice to use the connector provided or to solder the signal wire lines 
directly on the board. In both situation please follow the proper soldering process. Hand 
soldering is recommended.
