 14. Install R6, 1 megohm resistor [brown-black-green].

 15. Install R8, 22K ohm resistor [red-red-orange].

 16. Install R27, 220 ohm resistor [red-red-brown].

 17. Install R9, 22K ohm resistor [red-red-orange].

 18a. Examine the two small potentiometers. While they may be identical in

appearance, one is stamped 2.2K (R10, Sensitivity Control), and the other

is 10K (Calibration Control). Both of these controls are mounted on the

solder-side of the board so that adjustments can be made without

completely disassembling the LED Speed Readout unit.

 18b. Install R10, 2.2K potentiometer per step 18a.

 19. Between J1 and J2, install C21, 10µF electrolytic capacitor, observe

polarity.

 20. Install R26, 4.7K ohm resistor [yellow-violet-red].

 21. Install R25, 4.7K ohm resistor [yellow-violet-red].

 22. Install R7, 100K ohm resistor [brown-black-yellow].

 23. Install C12, 100 to 220µF electrolytic capacitor. Again, be certain to

install this and other electrolytic capacitors horizontally.

 24. Install C4, .01µF disk capacitor (marked .01 or 103 or 10nF).

 25. Install R5, 10K ohm resistor [brown-black-orange].

 26. Install R11, 100 ohm resistor [brown-black-brown].

 27. Install C6, 10µF electrolytic capacitor.

 28. Install C9, 10µF electrolytic capacitor.

 29. Install R16, 100K [brown-black-yellow].

 30. Install R14, 10K [brown-black-orange].

 31. Install R15, 100K [brown-black-yellow].

 32. Install C13, .01µF disc capacitor (marked 103 or .01 or 10nF).

 33. Install C17, .01µF disc capacitor.

 34. Install R28, 100K ohm resistor [brown-black-yellow].

 35. Install R22, 10K ohms on the solder side. This is the other small

potentiometer for Calibration Control.

 36. Install R21, 10K ohm resistor [brown-black-orange].

 37a. The correct value for electrolytic capacitor C20 is determined by the

manufacturing code of the 4093-type IC chip actually supplied in your kit.

Your kit may include either of two capacitors:

1 2 ... 11 12 13 14 15 16 17 18 19 20 21 ... 35 36
