Heart Rate Measurement Precautions
Heart Rate Measurement Functions
- The back cover of the watch has a built-in sensor that detects your pulse. This is used to calculate and display an approximate heart rate value. The factors below can cause error in the displayed heart rate value.
- How the watch is affixed to the wrist
- Individual wrist characteristics and condition
- Training type and/or intensity
- Sweat, dirt, and/or other foreign matter around the sensor
All of this means that heart rate values displayed by the watch are approximate, and no guarantees are made concerning their accuracy.
- The heart rate measurement function of this watch is intended for recreational purposes, and should not be used in any way for medical purposes.
- Heart rate measurement is automatically disabled when the battery level indicator shows
or lower.
Wrist Heart Rate Measurement Sleep (Power Saving)
Regardless of whether or not you are wearing the watch, the heart rate measurement sensor will automatically stop measurement and enter a sleep state if you do not move for a certain amount of time.
If heart rate measurement does not start when you strap the watch onto your wrist, it will start when you move your wrist.
