Troubleshooting Heart Rate Signal Reception
If your Polar training computer / sensor is not working as it should, try troubleshooting before contacting your closest Polar Service. If the above information did not help, please contact your local Polar Service here.
The heart rate sensor should be worn flat against the skin, Polar logo in upright position. See example here.
Read more on Maintenance of heart rate sensor with textile strap or on T31 and T31C Transmitters. See also video instructions.
Relocating the training computer or adjusting the heart rate sensor on your body may help. For a list of possible sources of disturbance, see Abnormal Heart Rate Readings During Exercise.
ECG signal strength varies depending on the individual’s tissue composition. The percentage of people who experience difficulties measuring heart rate is higher in water environment than in normal use.
Seawater and swimming pool chemicals can affect ECG signal reception. Do not press buttons under water as it may cause leaking. For more on Polar products in water, see Polar Products in Water Environment.
If the display has frozen, try resetting it. See user manual for instructions.
