Assembly Instruction (Delay)

Step 2:

• Solder 8 pins IC socket

• IC2 using 2 pieces of 8 pin socket

Step 4:

• Solder wafer connector(CN1)

• Solder ceramic capacitor(C9, C13)

• Solder Electrolytic capacitor(C4, C5, C6, C19, C20, C21)

• Make sure the positive lead(long lead) inserts to square soldering pad (+)

Step 6:

• Place the IC(IC1, IC2) on the IC socket

• White dot on PCB is pin 1
