Troubleshooting; Heart-Rate Signal Missing; Gps Signal Missing - Fitbit Zip Ionic User Manual

Troubleshooting

If your watch is not working properly, review our troubleshooting guidance 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. 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. 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.
For best results, wait for Ionic to find the signal before you start your workout.
