• 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
GO WATCH on your wrist. For example, move GO WATCH right, left, up,
or down on your wrist to adjust the position of the heart measurement
sensor. Or, wear GO 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.
