3. Why can't you take a hot bath with the smart bracelet?
Answer: Bath water temperature is relatively high, there
is a lot of vapor in the gas phase, with small molecular
radius, and it can easily infiltrate into the smart bracelet
from the shell gap; when the temperature drops down,
it will condensate into liquid droplets, which will easily
cause short circuit inside the smart bracelet, damage
the circuit board, and then damage the smart bracelet.
Note: For more common questions, please refer to Da
Fit APP feedback.
Warning:
Please consult your doctor before you take part in a
new sport. The smart bracelet should not be used for
medical purpose though it may monitor the heart rate
in the real-time and dynamic way.

disposed of in “separate collection” and so the product must not be
