Occasionally after using the HRM-Run chest strap during an activity, when the watch reverts to the optical HRM my resting HR shows as extremely high (normally 35-40 bpm, but will show as 100+ bpm). The only way to correct the issue seems to be to do a soft reset. Not a huge problem, but somewhat annoying. Anyone else ever have this issue?
Are you sure the chest strap is not still connected? Happens to me after I performed a run. I stop and save the activity, watch goes back to main screen (clock) and I remove the chest strap from my chest. The strap appears to stay connected and sends readings of 240+ to the watch.
