NOTE
Wearing your watch too loosely or moving excessively may cause inaccurate
•
measurements.
Escaping light may lead to inaccurate measurements. Do not wear the device
•
so that it is directly over your wrist bone when taking measurements.
WARNING
Never look directly at the heart rate sensor light as this may damage your
•
eyes.
Getting Accurate Measurements
Heart rate readings may be inaccurate depending on the conditions
and your surroundings. Follow these steps for more accurate heart rate
readings:
Never measure your heart rate after smoking or drinking alcohol.
•
Smoking and/or alcohol can affect your heart rate.
Never take heart rate measurements at low temperatures. Keep
•
yourself warm when you measure your heart rate.
Users with thin wrists may find their heart rate measurements are
•
inaccurate.
When measuring your pulse for workout purposes, take the
•
measurement while seated and relaxed before exercise, then proceed
with your workout.
If the measurement significantly differs from predicted values, relax
•
and measure again in 30 minutes.
Confirm your pulse by taking repeated measurements (about 5
•
times).
If you speak, yawn, or breathe deeply during the measurement, you
•
may see inaccurate values.
Your circulation, blood pressure, or skin condition can affect the light
•
reflection process and may lead to inaccurate measurements.
If light reflection is blocked by body hair or other items, you may
•
obtain inaccurate measurements.
