17. Visual check
At this point, brush the solder side with a hard tooth brush to remove any remaining solder bits.
Make a full visual check. Any missing component on the board ? Any remaining component in the box ?
When everything looks correct, proceed with the other boards assembly.

18. Anti-clic resistor networks
Insert and solder 8 resistor networks at the back of the PCB. These parts are all the same but have a
direction.
Warning
: Check the direction which is identified by a dot on the part and on the PCB.
19. Film capacitors
Add the film capacitors of the switch PCB (blue identifier in the parts list).
20. Resistors
All the resistors are inserted vertically.
Add the resistors of the switch PCB (blue identifier in the parts list).
21. Push switches
Insert the push switch SW5, flat on the PCB, in the correct direction and solder one pin. Check again
the good position then solder the other pins.
Warning
: The switch direction is given by the digits 2 0 1, engraved on one side of the switch. Match
the digits with the ones on the PCB.
Insert the switch cap.
