1, the mobile APP is not connected to the device: Smart weighing scale needs to connect to the OKOK Health App for the first time, and then your relevant personal information will be transmitted to weighing scale for recording and testing.
2. Wear shoes and socks: Because of BIA bio-impedance technology adopted by OKOK, when you stand on the weighing scale wearing shoes and socks, you may not be able to detect your body data because BIA current cannot circulate normally in your body.
