The first time you turn on your speaker, it is ready to pair and connect your first device. To pair and connect your device, follow these steps:
On your speaker, press POWER. The Bluetooth® status indicator on the speaker blinks blue to show that the speaker is discoverable
On your device, turn Bluetooth® on
Locate the Bluetooth® device list and select the device named "Bose SLIII". If your device prompts you for a passcode, enter "0000" (four zeros)
When pairing is complete and your device is connected to the speaker, the Bluetooth® status indicator on the speaker changes from blinking blue to solid white and the speaker emits a tone.
