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. Doing so may impair your
vision. Make sure children do not look directly at the lights or their vision may be
impaired.
•
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.
•
If any water, dust, or stains are on the infrared temperature sensor, the measurements
may be inaccurate.
•
Clean the infrared temperature sensor with a soft cloth or cotton bud.
