Using call features

Using the earbuds

•Because the heart rate sensor uses light to approximate heart rate, its accuracy may vary due to physical factors that affect light absorption and reflection, such as blood circulation/blood pressure, skin condition and location and concentration of blood vessels.

•If obstructions between the heart rate sensor and your ear, such as body hair, dirt, or other objects, prevent the light from reflecting evenly, measurements may be inaccurate.

•The accuracy of the heart rate sensor may be diminished when you are trying to measure infants’ heart rates.

•If the heart rate sensor is dirty, clean it before use.

•If the heart rate sensor is damaged, measurements may be inaccurate.

•If your earbuds become hot to the touch, stop measuring and remove them from your ears. Extended exposure of skin to hot earbuds can result in burns.

When the earbuds are connected to a mobile device, you can answer and control calls from the connected mobile device.
