Troubleshooting
If your watch is not working properly, review our troubleshooting guidance below. Visit help.fitbit.com
for more information.
Heart-rate signal missing
FB504 & FB505 continuously tracks your heart rate while you’re exercising and throughout the day.
Occasionally, the heart rate on your watch 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 watch correctly, either
moving it higher or lower on your wrist or tightening or loosening the band. FB504 & FB505 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.
Can’t connect to Wi-Fi
If FB504 & FB505 can’t connect to Wi-Fi, first make sure that you’re attempting to connect your watch
to a compatible network. For best results, use your home or work Wi-Fi network. FB504 & FB505 can’t
connect to 5GHz Wi-Fi, WPA enterprise, or public networks that require logins, subscriptions, or
profiles. For a list of compatible network types, see Connect to Wi-Fi.
After verifying the network is compatible, restart your watch and then try connecting to Wi-Fi again. If
you see other networks appear in the list of available networks but not your preferred network, move your
watch closer to your router.
If you’re trying to download personal music or podcasts, make sure FB504 & FB505 and your computer
are connected to the same Wi-Fi network. To do so, review the steps in Music and Podcasts. For a
stronger Wi-Fi connection, move your watch closer to your router.
If you’re trying to download Pandora stations, first make sure your Wi-Fi network is working correctly.
Try connecting another device to your network. If it connects successfully, try again to download your
station. Note that stations download automatically when the watch is charging and in range of your Wi-Fi
network, or tap Force Sync Now in the Fitbit app to add the stations to your watch.
