Low heart rate display during exercise?
If you are experiencing "low" heart rate readings during exercise please check to make sure your monitor is not set to display heart rate as a percentage of your maximum HR. If this is the case you will notice a % icon next to the heart rate display in measurement or exercise mode.
Please refer to your user manual for instructions on how to switch the heart rate display back to BPM. If you do not have your user manual, you can download an electronic copy from the following link.
