Before Felik can be used with the mobile app, you must pair it. Pairing provides a way to protect your Felik from unauthorized use.
To pair a new device go to Menu > Device Management and wait for your new device to be detected. When you see your device, you can simply tap on it to begin the pairing process.
Note that you should be connected to the same Wi-Fi network as Felik. If Felik is emitting a hotspot, you should be connected to that hotspot.
