 Note : In application, J3, J5 should be closed , and J2 ,J4 should be open. 
6-1-2.The metal-bezel is set be on ground when the J1 is closed . . 
Note: In application ,J1 should be closed. 
6-1-3.The LED resistor should can be bridged when the J6 is closed. 
Note: In application J6 should be opened. 
6-1-4.The R7 and the R8 are the LED resistor. 
 Note: In application, R7=R8=10 Ohm
