If your Polar H6 / Polar H7 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 and H7 are not compatible with earlier Bluetooth versions.
Check out the compatibility requirements.
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.
iPhone 4S and iPhone 5 do not show Polar H6 / H7 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.
- Battery lifetime of Polar H6 is about 300 hours.
- Battery lifetime of Polar H7 is about 200 hours.
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.
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.
If possible, try if the heart rate sensor works with some other compatible application or with some other compatible device.
