Once the two speakers are successfully paired for the first time, for the next time, the two speakers will connect to each other
automatically.

and red alternatively, search on your Bluetooth device (phone, tablet or computer) and find “KNZ GoDuo” to connect. You will hear a
prompt “Bluetooth connected”, which means the speakers are successfully connected with your Bluetooth device.
