How to wear the Watch for accurate measurements

For accurate measurements, wear the Watch firmly around your lower arm above the wrist
while leaving a finger's worth of space as shown in the figure below.

• If you fasten the Watch too tightly, the skin irritation may occur and if you fasten it
too loosely, friction may occur.
• Do not look directly at the optical heart rate sensor's lights. Make sure children do not
look directly at the lights. Doing so may impair your vision.
• If the Watch becomes hot to the touch, remove it until it cools. Exposing your skin to
a hot surface of the Watch for a long time may cause low-temperature burns.
• Remove all water from your Watch and the band before measuring your body
composition and ECG.
