Troubleshooting
If Sense 2 isn't working properly, see our troubleshooting steps below.
Heart-rate signal missing
Sense 2 continuously tracks your heart rate while you're exercising and throughout
the day. If the heart-rate sensor on your watch has difficulty detecting a signal,
dashed lines appear.
If your watch doesn't detect a heart-rate signal, make sure you're wearing your
watch correctly, either by moving it higher or lower on your wrist or by tightening
or loosening the band. Sense 2 should be in contact with your skin. After holding
your arm still and straight for a short time, you should see your heart rate again.
For more information, see the related help article.
GPS signal missing
Environmental factors including tall buildings, dense forest, steep hills, and thick
cloud cover can interfere with your watch's ability to connect to GPS satellites. If
your watch is searching for a GPS signal during an exercise, you’ll see the GPSicon
rotating at the top of the screen.
