Last week, I started noticing that my HRM was dropping randomly during
my runs, but the SDM Pod seemed to be working just fine. Then early
this week, the pace started getting erratic as well. So I replaced
the batteries in the watch and the HRM. Everything went fine and the
SDM and HRM linked up again fine. I went for a run tonight and I had
the same thing happen. Both the SDM and the HRM dropped at multiple
points during the run. After I finished my run, I noticed that if I
got the watch closer to the HRM or SDM that it would pick up a signal
again. Has anyone noticed anything like this or do I need to contact
Nike Service? Also, has anyone had any experience with the Nike
Service Center? Thanks in advance for any help!
