Heart rate monitor troubleshooting

In this article we will review:

  • Putting on the band
  • Powering on
  • Charging
  • What the lights mean
  • Initially getting connected
  • Disconnecting while playing
  • Inaccurate readings

Putting on the band

The band should be worn on the non-dominant forearm or bicep, away from the wrist and elbow. The green sensor lights should be directly against the skin and the monitor should be snug enough that it doesn't move around.


Powering on

To turn on the monitor, push down on the front of the monitor for approximately 5 seconds until the lights begin flashing. If there are no lights, first try charging the heart rate monitor


What the lights mean


Two red lights mean the battery is low and will need to charge very soon.

Initially getting connected

If you are having trouble connecting while setting up, there are a few factors to consider:

  • Not everyone's body is the same. You may need to adjust the position of the monitor. Test it out on a family member to see how quickly it responds.
  • The battery is low. Ensure you have a full charge before setting up.
  • Restart the tablet. Turn off the heart rate monitor and reboot your tablet. Then, wait until prompted by the Mightier app to turn the monitor back on.

Disconnecting while playing

The most common causes of disconnections are from a low battery, or from an inconsistent reading as a result of the way the heart rate monitor is being worn.

Rule out battery issues by charging the monitor fully before playing.
Ensure that you are wearing the heart rate monitor correctly. If the monitor is shifting frequently due to discomfort or fit, some kids have seen success by wearing the monitor on their calf.

Inaccurate readings

The monitor responds differently to different players by establishing a baseline heart rate each time you get connected. As each player progresses, the difficulty level will increase which determines how frequently the red zone of the Gizmo grows. This setting is so kids will continue to practice skills and become aware of the more subtle changes in their heart rate. 

If the difficulty is too high, kids may struggle to get out of the red. If it is too low, they'll never leave the blue. These settings can be altered by our Family Care Team. 

To adjust difficulty settings, troubleshoot any issues with the heart rate monitor, or for any questions about how the play time is reported on your dashboard, please contact the Family Care Team.
