1. Turn the two speakers on.
2: Press the Bluetooth button for both of the two speakers at the same time until the Bluetooth lights starting flash blue
3: Wait for a couple of seconds, there will be a beep sound which means the two speakers pair successfully. Also, there will be a solid blue indicator for a speaker and a flashing white indicator from the other speaker. The speaker which has a flashing white indicator is the main speaker, then you can pair your device with the main speaker.

 (Notes: Avoid placing any electronic devices between the two speakers. Make sure the distance between the two speakers is not more than 5 meters. The solid blue light speaker is the right channel. )
