1.Turn the two speakers on.
2. Hold the Bluetooth button on both the speakers for a few seconds simultaneously until the bluetooth light flashs white.
3. Wait for about 5-8s, there will be a beep sound which means the two speakers pair successfully. Also, there will be a solid white indicator for a speaker and a flashing Bluetooth indicator from the other speaker. The speaker which has a flashing Bluetooth indicator is the main speaker, then you can pair your device with the main speaker.
Avoid having any electronic devices between the two speakers. Make sure the distance between the two speakers not greater than 5 meters/16.4 feet.
