Witty User Manual - EN - v1.5 P. 62 / 171
Starting from the WittySEM 2.0.4. firmware version, the traffic lights can be used instead of the photocells
by placing them AFTER the traffic light that serves as a Direction Change in order to finish the test (instead of
crossing the photocell beam, bring your hand close to the traffic light).
Example: The A Index traffic light displays the arrow of the direction chosen, whereas the B and C traffic
lights turn Blue and one of the two must be "off" when bringing your hand close to it to finish the test.
If we have several traffic lights that serve as Direction Change (and therefore Number of Repetitions >; 1),
the first are for selection and the others act as a photocell.
