8. .Step 8: Install 1pcs 1Mohm Metal Film Resistor at R3. Its color is brown/black/black/yellow/brown.

9. .Step 9: Install 2pcs DO-35 1N4148 Diode at D1,D22. Pay attention to the installation direction. There is a black mark on 1N4148 and a white mark on PCB which are used to confirm the installation direction.

10. .Step 10: Install 4pcs DIP-8 IC Socket at U1,U2,U3,U4.There is a mark(notch) on one end of the IC Socket and there is a mark(curved silk screen printing) on PCB where the IC Socket can place on.These two marks are corresponding to each other and are used to specify the installation direction of IC Socket .

11. .Step 11: Identify the positive(anode) and negative(cathode) lead of LED.The leads of the LED must be installed correctly, otherwise the LED cannot be turned on.Here are four methods as following:

12. .According to the length of the LED lead to distinguish. The longer pin is positive(anode) lead. The shorter pin is negative(cathode) lead.

13. .Identify the negative(cathode) of the LED is to look into the plastic case where one can see that the negative(cathode) is much thicker/bigger inside the plastic case than the anode lead.

14. .Identify by edge of plastic case.The negative(cathode) lead of the LED should be the pin nearest the flat on the plastic case.

15. .Test by 3V battery or multimeter.The pin is positive(anode) lead which has connect to the positive of 3V if LED can light up after connect 3V power supply.(LED should not be powered directly from the 3V for a short time:less then 0.5second)

16. .It is positive(anode) where the white mark ‘ + ’ pointing to on PCB.

17. .Step 12: Bend LED pin to 90 degrees as showing.Pay attention to bending point and bending direction.

18. .Step 13: Install 4pcs 5mm Pink LED at D2,D3,D4,D5.
