Alerts – vibration or sound
FR910xt can alert you by:
- vibration
- sound
Alerts will keep you informed about any adjustments you need to make to keep your pace up or for example the new nutrition alert, which reminds you of taking your supplement.
Vibrating alert is really useful especially when running or cycling in noisy areas such as in urban areas or near the road.


Does the vibration function also work with “wake up” alarm…I usually sleep with earplugs so that feature would be awesome! Also, how many “wake up” alarms can one set?
