NFC (Near Field Communication) can be used to setup a Bluetooth connection between an Android or Windows Phone and the Libratone speaker.
Sometimes the NFC Bluetooth setup fails and you need to start all over. In Settings + Bluetooth on your mobile device - delete the Libratone Bluetooth pairing and switch Bluetooth OFF/ON. Enable Bluetooth pairing mode on your speaker by pressing and holding the Bluetooth button for approx 2 sec until the logo button emits a blue sequence. Hover your Android or Windows Phone over the logo button until you see a Bluetooth pairing request on your mobile device. Once the speaker and the mobile device is paired through Bluetooth - the music will automatically be transmitted to your speaker.
You can also pair your mobile device and your speaker without using NFC. In Settings + Bluetooth on your mobile device - locate your Libratone speaker and tap to pair.
NOTE: iOS devices (iPhone, iPad, iPod touch) doesn't support NFC for Bluetooth paring. In Settings + Bluetooth on your iOS device - locate your Libratone speaker and tap to pair.
