Troubleshooting your Fitbit Alta HR
If your tracker is not working properly, review our troubleshooting guidance below.
Visit help.fitbit.com for more information.
Heart-rate signal missing
Alta HR continuously tracks your heart rate while you’re exercising and throughout
the day. Occasionally the heart rate tracker may have difficulty finding a good signal.
When this happens you’ll see dashed lines where your current heart rate usually
appears.
If you’re not getting a heart rate signal, first make sure you’re wearing your tracker
correctly, either moving it higher or lower on your wrist or tightening or loosening
the band. After holding your arm still and straight for a short wait, you should see
your heart rate again. If the heart rate signal is still missing, check your Heart Rate
setting on your Fitbit dashboard and make sure it’s set to On or Auto.
Unexpected behavior
If you experience one of the following problems, it may be fixed by restarting your
tracker:
•! Not syncing despite successful setup
•! Not responding to taps despite being charged
•! Not tracking your steps or other data
Note:
Restarting your tracker reboots the device but does not delete any data.
To restart your tracker:
1.! Plug the charging cable into the USB port on your computer or a UL-certified
USB wall charger.
2.! Clip the other end of the charging cable to the port on the back of the tracker.
The pins on the charging cable must lock securely with the port. You’ll know
the connection is secure when the tracker vibrates and you see a battery icon
on your tracker’s display. The battery icon disappears after three seconds.
