Frequently Asked Questions (FAQs)

1. Why does the Smart Watch automatically disconnect Bluetooth when the

Android screen goes out?

1> Lock background APP. When the Da Fit process is cleared, the Smart Watch will be disconnected from the mobile phone. Set APP self-startup Unrestricted background operation. The Android mobile phone installed with APP intelligently restricts the background operation by default, and App should be set manually without any restriction.

Why cannot the Smart Watch receive message push?

Why can't take a hot bath with the Smart Watch?

Answer: the bath water has a relatively high temperature, and generates a lot of vapor which is in the gas phase with small molecular radius and can easily infiltrate into the Smart Watch from the shell gap. When the temperature drops down, the vapor will condensate into liquid-phase droplets which will easily cause the short circuit inside the Smart Watch and damage the circuit board and then damage the Smart Watch.

Warning:

Please consult your doctor before you take a new sport. The Smart Watch should not be used for any medical purpose though it may dynamically monitor the heart rate at real time.
