The heart rate figures may not be accurate depending on measurement conditions and surroundings.
Take heart rate measurements when you are seated and relaxed.
If heart rate measurements are taken at low temperatures, the result may be inaccurate.
Do not move your body while taking heart rate measurements. Doing so may cause your heart rate to
be recorded inaccurately.
Users with thin wrists may receive inaccurate heart rate measurements.
Inaccurate measurements occur when the device is loose and the light used to provide the
measurement is reflected unevenly.
If the measurement is very different from the expected heart rate, rest for 30 minutes and then
measure it again.
Measurements are calculated using average values and should be repeated at least five times.
During winter or in cold weather, keep yourself warm when measuring your heart rate.
Smoking or consuming alcohol before taking measurements may cause your heart rate to be different
from your normal heart rate.
Do not talk, yawn, or breathe deeply while taking heart rate measurements. Doing so may cause your
heart rate to be recorded inaccurately.
If your heart rate is extremely high or low, measurements may be inaccurate.
Obstructions between the device’s strap and your wrist, such as body hair or other objects, may
prevent the light from reflecting evenly.
Heart rate measurements taken for infants and toddlers may be inaccurate.
Do not look directly at the heart rate sensor’s lights. Doing so may impair your vision.
