To restore your speaker cube to factory default settings:
- Unplug the power supply from the speaker cube.
- With the speaker unplugged and unpowered, press and hold the Power/Mode button.
- While holding the Power/Mode button, connect the speaker to AC power.
- Continue holding the Power/Mode button for ten seconds, until the lights flash green.
The system resets, the Bluetooth indicator light blinks blue, and you hear, “Ready to pair.”
