Polar H7 Not Pairing? Discharge It

I you have a Polar H7 that all of the sudden was unable to pair, you may need to discharge the sensor. To do so:

  1. Trash the Pairing. Go to Settings -> My Sensors -> Heart Rate Monitors -> Bluetooth Smart -> Details -> Delete. This step is only needed if the H7 is “ON”.
  2. Remove the battery from your Polar H7. Using a coin, open the battery cover by turning it counterclockwise to OPEN. Remove the cap. Using a sharp edge (knife), lift the battery out from inside the cap.

    Note: When removing the battery, make sure the sealing ring is not damaged, in which case you should replace it with a new one. You can purchase the sealing ring/battery kits at well-equipped Polar retailers and authorized Polar Services.

  3. Close the back of the peanut that used to house the battery, and clip it on to the belt, without the battery.
  4. Put sensor on and wear for 30 seconds to 1 minutes
  5. Remove H7 peanut and insert battery. Remount on chest
  6. Re-pair the H7 with Fitdigits by going to Settings -> My Sensors
