Polar Power s720i output meter is broken…
Darn it, I like the monitor, but thing has mysteriously died. I get heart rate and speed, but I don't get cadence or power anymore. Sent a note to the folks at Polar and they think:
_If the Power sensor shows green light, then cadence should work. Have you chosen the cadence ON (also power) in your wrist unit (options - bike set)? Other possibility is that the chain speed sensor or its' wire is broken (yellow led is not blinking). On that case you can contact your local distributor for further assistance, you can find the contact information at "Polar":http://www.polar.fi/polar/channels/eng/polar/contact.html_
So it has to go back to the shop. Too bad I actually like the thing and was just getting used to training by watts.
