MP071B CPU JUMPER SETTING 

OP=OPEN CL=CLOSE 

Before installing the CPU, make sure that the CPU VOLTAGE SELECTOR is set 
properly. Please refer the CPU VOLTAGE SELECTOR, wrong setting will damage 
the CPU. 
NOTE: CPU has two different types of voltage (A)Single Voltage (B)Dual Voltage

CPU VOLTAGE SELECTOR 
MP071 is designed to support different types of CPU with Single or Dual voltage. 
NOTE: For Dual Voltage CPU, make sure JP13 and JP19 is set properly, WRONG setting 
will cause Voltage Output Conflict and will DAMAGE the CPU.
