I can't get X02 and UNIT-4 to pair

If you're unable to pair the X02 with UNIT-4 speakers, follow these steps:

1. Turn on both UNIT-4 speakers
2. Leave X02 unplugged for now (power off)
3. Make sure both are in W+ mode - use the Mode button on the back
4. Hold the Mode button on UNIT-4 until the LED's start flashing 2x per second (hold for around 2-3 seconds)
5. Check that the LED's are flashing 2x per second on both UNIT-4's
6. If not - hold the Mode button on the other UNIT-4 to enter pairing mode
7. Plug in X02 to a power supply or your device
8. Wait for the LED's to turn on
9. Hold the button on X02 until all of the LED's are constantly on - no flashing. (Hold for around 2-3 seconds)
10. Pairing is complete.
