Measuring Your Heart Rate

Your watch includes a sensor on the back to detect your heart rate (ProSense57).

Caution:

The sensor light causes no adverse effects on your skin, but you should not look directly at the light.

Wear the product snugly around your wrist as shown. Tighten the watch if your heart rate is not measured correctly.

Note: Do not wear the product too tight. You should still be able to fit your little finger under the watch band. If you feel any discomfort, loosen the wristband.

Note: Do not wear the watch on the underside of your wrist or covering the ulna bone.

Once the watch has detected your heart rate, it displays your heart rate, heart rate zone, and the HR icon on the Time screen.

You can also press the

Up button to display the Heart Rate screen.

Note: If you see ––– on the display or the HR icon is flashing, the watch has not detected your heart rate. Make sure you are wearing the watch correctly and try again. If your heart rate often reads less than 120 beats while running or 70 beats while walking, you may have a naturally low heart rate. This can cause incorrect heart rate measurements. Set the HR Measurement option to Settings 2 in the Epson View app to correct the issue.
