scanner must meet the requirements for SELV (Safety Extra Low Voltage) according 
to EN/IEC 60950-1.  
 
  To maintain compliance with standard CSA C22.2 No. 60950-1/UL 60950-1 and norm  
EN/IEC 60950-1, the power source should meet applicable performance requirements for a 
limited power source.

1.  Locate the small ‘pin-hole’ on the side of 
the QuantumT near the cable. 
2.  Bend an ordinary paperclip into the shape 
shown. 
3.  Insert the paperclip (or other small metallic
