Hi,

Picked up a new Sigma ROX 6.0 CAD off Amazon, because my 10yr old Sigma computer died on me last weekend. Anyway, everything works well, as in heart monitor, and speed sensor, except the cadence, which i've only seen working for no more than a few seconds.

The battery has been replaced.
I've pressed the mode 1 button down for three seconds to re-sync everything
I've tried both magnets
I've even moved the unit right next to the head unit, and simulated by swinging the magnet over the sensor, (which makes that ever so slight blip noise)
The magnet can't get any closer, than its current 1mm !!!

But the cadence on the head unit just flashes as zero.

Anyone else have any idea's or am I just unlucky.

I'll call Sigma up tomorrow.. Hopefully they can sort me out quickly. If not I'll just send the thing back to Amazon for a refund / replacement.
