Use the Earbuds
•
Do not talk, yawn, or breathe deeply while taking heart rate measurements.
Doing so may cause your heart rate to be recorded inaccurately.
•
Because the heart rate sensor uses light to approximate heart rate, its accuracy
may vary due to physical factors that aect light absorption and reection,
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 reecting evenly, measurements
may be inaccurate.
•
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.
