The colors that your sensors display vary depending on what they're doing and their battery charge level, so interpreting them takes a little practice.  That said, in general your sensors 1-6 and H should ALWAYS be displaying the same color behavior, once the PIVOT Tennis app is open and connected to the PIVOT wi-fi network.

That said, if you do see an "odd man" sensor behaving differently from the others, follow this guide:

  • If the odd man sensor is a solid color (blue or green), restart all the sensors.
  • If the odd man sensor is the H sensor, and it's blinking red, restart it.
  • If the odd man sensor is sensor 1-6, and it's blinking red, that means the battery is low.  Recharge it.  (It's probably a good idea to recharge all sensors at the same time, too.)
