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

Putting on the band

Two different sized bands are included with each kit. Watch how to attach the band to the monitor and then put it on


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 3 seconds until the lights begin flashing. If there are no lights, first try charging the heart rate monitor


If the monitor is no longer charging at all, try a different outlet, preferably plugged directly into a wall socket instead of a power strip or adapter. 

If the battery is draining rapidly, try letting it deplete then leave it plugged in overnight before turning it back on.

What the lights mean

While the monitor is turned on, the lights will indicate the status:

  • Two red lights mean the battery is low and will need to charge very soon
  • Flashing red and blue lights mean the monitor is trying connect to the Mightier app
  • Two blue lights indicate the monitor is successfully connected
  • In some cases, purple lights will indicate the monitor needs to be reset by briefly charging

Initially getting connected

If you are stuck connecting before even getting to play, there are a few factors:

  • 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.
  • A low battery, we try to ship the equipment with enough juice to get started, but charging may be beneficial.
  • Reset the tablet, the monitor may be working fine and the issue is on the other end of the connection. Turn off the monitor and reboot the tablet then wait until prompted by the app time turn the monitor back on.

Disconnecting while playing

The most common causes of frequent disconnections are from a low battery or from an inconsistent reading. Rule out battery issues by charging the monitor for at least 1 hour before playing again.

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 even if they are not visibly frustrated. 

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, or for any issues with how the play time is reported on your dashboard or in a recent email, please contact the Family Care Team.
