If your Bluetooth device won't connect to your Logitech UE Boombox, try the following:

• Make sure your device is paired with your speaker and Bluetooth is active (see answer 360023249514 for pairing help).
• Place your Bluetooth device closer to the speaker — it might be out of range.
• Move your Bluetooth device and speaker away from other wireless sources — you could be getting interference.

NOTE: If this is the first time you're pairing a device with your speaker, you don't need to press the Bluetooth connection button. It comes out of the box ready to pair.
