Heart rate monitor
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.

•
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.
If heart rate measurement is not working properly, adjust the
position of Watch on your wrist. For example, move Watch right,
left, up, or down on your wrist to adjust the position of the heart
measurement sensor. Or, wear Watch with the heart rate sensor
firmly against the inside of your wrist.
• If the heart rate sensor is dirty, wipe the sensor and try again.
