Pairing Operating as below after confirmed the starting of ACW520-BT:
Long press the ACW520-BT in the scale until the yellow indicating light flash once. Long press the ACW520-BT which is connected to terminal, until the yellow indicating light flash twice. once the two adapters connect successfully, the green lights of both flash once. How to determine master and slave n the operation shown above, the ACW520-BT connected to scale is slave and the ACW520-BT connected to terminal is master. Slave: can be connected by other master devices and will record the address of the master in default when first connected. After that, it will not receive the query from other master. Master: will connect to one of the other paired slaves automatically. Configuration of master and slave:
Configuration type slave master 1 In the scale With the terminal search for the corresponding paired ACW520-BT through ACW520-BT After power on the adapter, single click the multi-function button, the indication light of paired adapter will flash at the same time. Yellow light flashing means salve and green light flashing means master. 3. Working mode Bluetooth adapter ACW520-BT can work in the mode of transparent transmission:
