Sigma bc 1609 kmh flashing but not counting I've just presented a new Sigma BC 1609 (wireless), assembled, put the sensor on the fork and a magnet on a spike, set the wheel size, looks fine.
But the speedometer does not work - it is just flashing?
Any hints?

Thank you.

update After watching the installation video on the Sigma web-site, understood that the gap was too big between sensor and the magnet. So the sensor shouldn't parallel to the wheel, but pointing towards it -
