Why does my device disconnect so frequently from the MASTER?

Your unit knows other networks as well and a connection has already been saved on it. If you move away from the Master, your device may automatically connects to another network. It is recommended to use your iPad/laptop only in connection with the Master, otherwise you must always make sure that your device is connected to the Master before you want to start a measurement. We recommend that you ignore other networks.
