After your Tacho5SAFE device appears on the main screen tap the QR code and scan the QR code from the back of your device. Make sure the identification number shown on the phone and on the device match otherwise you will not be able to connect to device later.

Try to move the phone or the Tacho5SAFE device in order to obtain a clear picture and make the camera able to scan the code properly.

After a successful scanning the camera will be closed and the phone will try to connect to the device.
