A factory reset will remove all personalized settings on your speaker (including remembered Wi-Fi networks and Bluetooth connections). If you choose to perform a factory reset, you will have to set up the speaker from scratch afterward.
To perform a factory reset on your ZIPP2 or ZIPP2 Mini, hold the Nightingale and the power button on the back of your speaker simultaneously for 10 seconds while the speaker is ON.
The reset has initiated when the lights in the touch interface begin rotating. As soon as the reset has completed, the speaker will automatically enter setup mode.
Note: It is also possible to perform a factory reset by using the Libratone App.
