Example: Top of tuning curve on right border
In this example the green LED and the red LED are flashing.
The time of the yellow LED is much longer than the time of the red LED (the red LED might not
be visible), that means the top of the tuning curve is on the right border (too much capacitance).
In this case it is recommended to remove one of the jumpers on ST1 and repeat the auto tuning
procedure.
