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 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.
