On the remote, press and hold the Bluetooth button until the light bar pulses Blue. This will allow the soundbar to be discovered by devices that can transmit its audio using a Bluetooth connection
On your mobile device, turn on the Bluetooth feature. If an option to 'Search for available devices' or 'Pair a new device' is shown, select this option
Look for the name you gave the soundbar when you set it up in the Bose Music app. If you didn't name your soundbar, the default name of Bose Soundbar 700 will appear. Select the name of the soundbar once it is shown in the list of available devices
Once the connection between your mobile device and soundbar is successful, the soundbar will play a tone and the light bar will glow solid White.
