1. Q: I can’t charge my watch / bracelet and it doesn’t power on, what should I do?
A: If this is the first time you’ve charged your watch / bracelet, please use the adapter to power it, charge it for more than 3 hours, then press the button to start it;
If you have not used the watch / bracelet for a long time without charging it, the battery would have opened the UVP function. In this situation, you need to activate the battery before using. (You can go to the phone repair shop to activate the battery).
2. Q: Why can’t I connect with Bluetooth?
A: 1. If the phone's Bluetooth version is lower than the watch's / bracelet’s, they will
not be able to pair;
