If you are not getting any successful heart rate measurements, your heart rate data seems inaccurate, or if you get different results than you do with a heart rate monitor, perform the following steps:
- Make sure your ScanWatch Light is properly positioned.
- Make sure you wear your ScanWatch Light tightly enough. It shouldn't be able to move around your wrist.
Note: You may notice inaccurate heart rate data if you wear a metal or leather wristband. - Make sure you've launched the continuous heart rate mode before starting your activity.
It can take up to 20 seconds for the first heart rate measurement to be displayed on your watch. - Make sure the sensor below your watch emits a blinking green light when the watch display is on.
- Make sure your watch is clean and your wrist is moisturized but not sweaty or overly wet.
Note: Excessively dry skin may result in repeated failed recordings. If necessary, wash and lightly dry off your hand before attempting a heart rate recording. You could also apply moisturizer to your hand to prevent dryness.
Please note that because of the clenched position the wrist is flexed in when cycling, the heart rate measurements may have some inaccuracies.
You can position your ScanWatch Light on the lower part of your wrist. Note that we cannot guarantee the accuracy of the heart rate data, because the product is not aimed to be positioned on the lower part of your wrist.
