How do I pair X04 with UNIT-4?

Turn X04 on after UNIT-4 is in W+ Link pairing. The first time, X04 starts in pairing mode on its own and both pairing LEDs flash fast.

Before you start

UNIT-4 includes X04. Hold the control button until the power LED turns on.

Steps

1. Turn each UNIT-4 on. Hold the middle button for 2 seconds.
2. Press the Mode button so the speaker is in W+ Link.
3. Hold the Mode button for 2 seconds.
4. Turn X04 on. Hold the control button until the power LED turns on. The first time, both pairing LEDs flash fast.
5. Connect your audio source to the USB-C or 3.5 mm mini-jack on X04.

To pair X04 again later, hold the Mode button on UNIT-4 for 2 seconds, then double press the X04 control button.

• The pairing LEDs are not flashing fast. Double press the X04 control button. Hold the Mode button on UNIT-4 for 2 seconds.
• The transmitter is X02. Please follow the steps in How do I pair X02 with UNIT-4?
