A: If this is the first time you have 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 entered the UVP function. In this situation, you need to activate the battery before using it. (You can just go to a phone repair shop to activate the battery).

A: 1. If the phones Bluetooth version is lower than the watch's/ bracelet's, they will not be able to pair
2. If the phones Bluetooth version is equal to or higher than the watch's/ bracelet's but is initially unable to pair, then you need to clear the Bluetooth connection history on the phone, scan and re-connect again.
