• 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.
Before You Start Exercising

particularly if you have any of the following conditions:
• Heart disease;
• Asthma or lung disease;
• Diabetes, or liver or kidney disease;
• Arthritis.
You should also check with your doctor if you have symptoms suggestive of
heart, lung, or other serious disease, such as:
• Pain or discomfort in your chest, neck, jaw, or arms during physical
activity;
• Dizziness or loss of consciousness;
• Shortness of breath with mild exertion or at rest, or when lying down
or going to bed;
• Ankle swelling, especially at night;
• A heart murmur or a rapid or pronounced heartbeat;
