common problem

1. Why does the bracelet automatically disconnect the Bluetooth connection after the screen of the Android phone is off?
1>. Lock the background APP.
After the Da Fit process is cleared, it will cause the bracelet to be disconnected from the phone.
2>Set the APP to start automatically.
3>Unlimited background operation.
The Android mobile phone installs the APP, and the default is to intelligently restrict the background operation, and you need to manually set the APP without taking any restrictive measures.
2. Why can’t the bracelet receive push notifications?
1>. Confirm that the message push switch is turned on on the mobile client.
2>. The confirmation message can be displayed normally in the notification bar of the mobile phone. The bracelet message push is pushed by reading the message in the mobile notification bar; if there is no message displayed in the mobile notification bar, the bracelet will not be able to receive the push.
(You need to find the notification settings in the phone settings, turn on WeChat, QQ, phone, SMS, The notification switch of the mobile client).
3> Open the phone — Settings, the top search box, enter “notification usage rights”, and re-open Da Fit.
3. Why can’t I wear a wristband to take a hot bath?
Answer: The temperature of the bath water is relatively high, it will produce a lot of water vapor, and the water vapor is in the gas phase, and its molecular radius is small, and it is easy to infiltrate from the gap of the shell of the bracelet. When the temperature drops, it will condense into liquid again.
Phase droplets can easily cause a short circuit in the internal circuit of the bracelet, damage the circuit board of the bracelet, and then damage the bracelet.

warning ：
Please consult your doctor before starting a new exercise.
Although the smart bracelet can monitor real-time dynamic heart rate, it cannot be used for any medical purposes.
