Troubleshooting Polar H6 / H7 / H10 heart rate sensor

If your Polar H6 / Polar H7 / Polar H10 heart rate sensor is not working as it should, try troubleshooting before contacting your closest Polar Service

Check from the receiving device's manual that it supports Bluetooth 4.0 (Bluetooth Smart) and its standardized heart rate service

Polar H6, H7 and H10 are not compatible with earlier Bluetooth versions.

Do you have a compatible receiving device or application in use?

Check out the compatibility requirements.

Check that you have paired the heart rate sensor with the application

If paring does not work, check that bluetooth on the receiving device is enabled.

When pairing, make sure you are far (10 m/ 33 ft) from other Bluetooth Smart heart rate sensor users.

If your receiving device has a bluetooth devices list, you can check if the sensor is paired. Polar H6 / H7 along with its ID number is listed when the sensor is paired. The ID numeber is printed on the back of the sensor.

iOS devices do not show Polar H6 / H7 / H10 in the bluetooth devices list.

For more on enabling heart rate sensor and starting the application, please see user instructions provided by the application manufacturer.

Check that you are wearing the heart rate sensor correctly


Could the heart rate sensor battery be getting empty?

Have you tried if changing the battery helps. See instructions video for H7 or H6 or H10.

  • Battery lifetime of Polar H6 is about 300 hours.
  • Battery lifetime of Polar H7 is about 200 hours.
  • Battery lifetime of Polar H10 is about 400 hours.

Is the receiving device positioned correctly?

Keep the receiving device in front of you to ensure sufficient transmission range. A good place e.g. for a mobile phone is in a front pocket or handlebar.

2.4 GHz radio frequency signal, which Bluetooth Smart uses, does not pass through human body, e.g. your arm.

Have you tried restarting the application and heart rate sensor?

Exit the application and remove the heart rate sensor from the strap. Wait 30 seconds, place the sensor back and start the application.

With H7, if the sensor restart didn't help, reset the sensor by taking battery out for 6 minutes and touch both snap connects for 10 seconds right after you have taken the battery out.

If your receiving device has a bluetooth devices list, try if removing the Polar H6 / H7 from the list and pairing it again helps

Remember to wear the heart rate sensor when pairing.

Try restarting the receiving device to see if it would help

If possible, try if the heart rate sensor works with some other compatible application or with some other compatible device.

My sensor is not working. What do I do?

A sensor can be in three different modes with Polar Beat. Check that the sensor you wish to use is paired with Polar Beat.

  • Not paired. To use the sensor, you need to pair it with Polar Beat.
  • Not active. The sensor has been paired with Polar Beat, but it is not currently active.
  • Paired. The sensor is paired with Polar Beat and is currently active.

If the issue persists, please contact Polar distributor in your country.
