Troubleshooting
If Ionic isn't working properly, see our troubleshooting steps below. Visit
help.fitbit.com
for more information.
Heart-rate signal missing
Ionic 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 device doesn't detect a heart-rate signal, first make sure heart-rate tracking
is turned on in the Settings app on your device. Next, make sure you're wearing
your watch correctly, either by moving it higher or lower on your wrist or by
tightening or loosening the wristband. Ionic 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.
If the heart-rate signal is still missing, open the Settings app
on your watch and
make sure Heart Rate is set to On.
GPS signal missing
Environmental factors including tall buildings, dense forest, steep hills, and even
thick cloud cover can interfere with Ionic's ability to connect to GPS satellites. If
your watch is searching for a GPS signal during an exercise, you'll see "connecting"
appear at the top of the screen.
