Heart Rate Sensor
Make sure your watch is
positioned on your wrist
correctly before measuring
your heart rate.
NOTE
• Wearing your watch too loosely or moving too much may cause inaccurate measurements.
• Never look directly at the heart rate sensor light as this may damage your eyes.
• Escaping light may lead to inaccurate measurements. Wear your watch below your wrist bone
so it sits flat against your skin to prevent light from leaking out while measuring your pulse.
