Heart Rate Fail
Posted: Thu Jun 25, 2015 5:22 pm
Yesterday and today HR was reading OK at the start of the ride but a few minutes in I got Heart Rate Fail, SPD/Cadence sensor was fine. Tried rescanning several times but the Newton never found the HR again. Before today's ride I our in a new battery and maybe the HR readings lasted 4 or 5 minutes longer before the Fail warning. (battery was fresh, exp. date is several years from now).
I did notice, starting 3 or 4 weeks ago, strange and incorrect HR readings when out of the saddle in the drops, chest closer to the Newton than usual. HR reading would sometimes spike 20 to 40% for 5 seconds or so, then return to normal when I was back on the seat. It's an iBike HR chest unit, can't make out a model number. I don't have another ANT+ heart rate device to check if it's receiving a signal. Any way to diagnose where the problem lies, Newton or strap, and any ideas how to fix?
BTW, the Newton upgraded to FW 5.08 a day or two before this started..
