Troubleshooting your Fitbit Blaze
If your tracker is not working properly, review our troubleshooting information
below. For other problems or more details, visit http://help.fitbit.com.
Heart-rate signal missing
Blaze continuously tracks your heart rate while you’re exercising and throughout the
day. Occasionally the heart rate tracker may have difficulty finding a good enough
signal to show a heart rate.
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 a short wait, you should see your heart rate again. If a heart rate
signal is still not found, check your Heart Rate Tracking setting in your tracker’s
Settings menu 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 button presses, taps, or swipes
• Unresponsive despite being charged
• Not tracking your steps or other data
Note: Restarting is not the same thing as shutting down your tracker. The Shut
down option is available in the tracker’s Settings menu to help you preserve
battery life. Restarting your tracker as described below reboots the device.
Restarting your tracker does not delete any data except call, text, and
calendar notifications.
