Fastening IC Socket Connector 
CAUTION 
  1.  Use the screwdriver provided for tightening screws. 
  2.  The tightening torque must be 0.294 N•m or less.   
   
If the applied torque cannot be accurately measured,  
   
stop tightening when the force required to turn the screw  
   
becomes significantly greater than that needed when first  
   
tightening.  If a screw is tightened too much, the screw  
   
head may break or an IC socket contact error may be  
   
caused by a crack in the IC socket solder. 
  3.  If the emulator does not operate correctly, cracks might  
   
have occurred in the solder.  Check conduction with  
   
a tester and re-solder the IC socket if necessary. 
Fasten the user system interface board to the IC socket on the user system with four screws  
(M2 
×
 12 mm) provided. 
Take special care, such as manually securing the IC socket soldered area, to prevent the soldered 
IC socket from being damaged by twisting the components.
