Frequently Asked Questions (FAQs) 1.Why does the smart bracelet automatically disconnect Bluetooth when the Android
screen goes out? 1>Lock background APP. When the Da Fit process is cleared, the smart bracelet will
be disconnected from the mobile phone. 2 >Set APP self-startup 3 > 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.
2. Why cannot the smart bracelet receive message push? 1> Please confirm that you have turned on the switch for message push at the mobile phone client. 2 > Please ‘confirm that messages can be displayed normally in the mobile phone
notification bar. The message push on the smart bracelet is completed by reading the message from the mobile phone notification bar. The smart bracelet will not receive the message push if there is no message in the mobile phone notification bar. (You need to find notification settings in the mobile phone settings, and turn on the notification switch of WeChat, QQ, call, SMS and mobile phone client).
3 >Turn on the mobile phone — Settings. Enter “Notification use right” on the top search box, re-open Da Fit.
3.Why can’t take a hot bath with the smart bracelet? 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 bracelet 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 bracelet and damage the circuit board and then damage the smart bracelet.
