• The accuracy of the heart rate sensor can be affec-
ted depending on the user's movements, personal
physiology, and the measurement conditions and
surroundings. Take heart rate measurements when
you are seated and relaxed.
• Do not look directly at the heart rate sensor's lights.
Doing so may impair your vision.
• If your device becomes hot to the touch, please
remove it until it cools.
Exposing skin to a hot surface of the device for a
long time may cause skin burn.
