Troubleshooting Polar H9 / H10 heart rate sensor

If your Polar H9 / Polar H10 heart rate sensor is not working as it should, try troubleshooting with the following instructions.

Follow the care instructions to ensure reliable measurement and to maximize the life span of the heart rate sensor.

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 H9 / H10 along with its ID number is listed when the sensor is paired. The ID number is printed on the side of the sensor (see the image below).

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

Polar H9 and H10 are not compatible with earlier Bluetooth versions. If paring does not work with ANT+ or Polar GymLink (5kHz) receiving device, check from H9/H10 settings that the connection you are using is enabled.

For example, with Polar Beat a sensor can be in three different modes.

  • Not paired. To use the sensor, you need to pair it with Polar Beat. Please note that you need to wear the sensor when pairing it.
  • 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.

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.

If the receiving device is a mobile device, restart its Bluetooth connection before pairing the sensor again. Remember to wear the heart rate sensor when pairing.

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

To reset your heart rate sensor:

  1. Remove the battery.
  2. Press the metal snaps that attach to the strap with your fingers for at least 10 seconds.
  3. Wait 30 seconds and then put the battery back in.

Sensor pairing with a Polar or third-party device or app is required after the reset if you are using a firmware version earlier than 3.3.1 for H10 and 1.2.1 for H9.

Connect the heart rate sensor with Polar Beat to see if a newer firmware version is available. Check out the instructions on updating the firmware.

Have you tried if changing the battery helps. See instructions video for H9 or H10.

Static electricity, technical sportswear and special conditions

If air humidity is low or you are exercising in windy conditions (for example high-speed road racing), a fluttering shirt may rub the heart rate sensor and generate static electricity. This causes additional signals, especially if the contact between skin and heart rate sensor is poor. To avoid this:

  • Moisten the electrodes before use or, if your strap has plastic electrodes, you can use conductive lotion or gel.
  • Use a cotton shirt instead of a synthetic shirt.
  • Use a tighter shirt to avoid fluttering of the material.
  • Use the heart rate sensor on a wet shirt.
  • Try placing the heart rate sensor slightly to the left.


Polar products are not designed to detect arrhythmia or irregular rhythms and will interpret them as noise or interference. In most cases the Polar training computers work fine for persons with cardiac arrhythmia, but in some cases (many abnormal heart beat intervals) arrhythmia may cause incorrect heart rate readings.

If the issue persists, please contact your local customer care.
