How to Use in Bluetooth Mode?
First, press the “BT” button once to enter Bluetooth mode. The Slumber will enter PAIRING mode automatically on first time use. If not, put your Slumber into PAIRING mode by pressing & holding the “BT” button until the LED flashes blue and red alternately.
Next, turn on your device's Bluetooth and select "Avantree Slumber" to connect. Keep them close together. After a few seconds, they’ll connect. Once connected, the Slumber’s Bluetooth connection indicator will turn solid blue.
Note: The Slumber automatically reconnects to its last-paired device when switched to Bluetooth mode; if not, it can be manually reconnected by tapping the “BT” button or selecting "Avantree Slumber" in your device's Bluetooth menu.
