STEP 1
The Slumber must be connected to a power source via the provided power cable in order to function. Plug the provided type C charging cable into the charging port, then connect the other end to a 5V/500mA-2A rated USB adapter (your phone charger or similar should work) or PC USB port.

Slide the ONOFF switch to the "ON" position to turn the Slumber on.
Choosing an Audio Mode
You can choose to stream audio in three different ways: via MP3, Bluetooth, or AUX. The Slumber will default to the last-used mode each time it's powered on.
MP3 Mode
For first time use, the Slumber will enter MP3 mode automatically, playing the built-in white noises. If not, press the MP3 / AUX button once to enter MP3 mode manually. You can change the playback mode by pressing & holding the MP3 / AUX button until the corresponding indicator turns solid white.
11 Ordered playback
1-2 Single cycle playback
Shuffle playback
The Slumber contains a built-in 4GB storage card that it uses while in MP3 mode. In addition to the 10 enclosed white noise options, you can upload your own tracks by connecting the Slumber to your PC via the included USB C cable. Transfer your chosen files to the "Avantree Slumber" disc and enjoy!
AUX Mode
Plug the AUX 3.5mm audio cable into both the Slumber and your audio output device (i.e. your phone / PC / tablet), and the Slumber will enter AUX mode automatically. If not, press MP3 / AUX once to swap from MP3 mode or twice if you're swapping from Bluetooth mode.

Keep them close and wait for 5-10 seconds or until they connect. Once connected, the Slumber's Bluetooth connection indicator will turn solid blue.
For subsequent use, the Slumber should automatically reconnect to the last-paired device within a few seconds of being switched to Bluetooth mode. If not, you can manually activate reconnection by tapping the BT button once, or by selecting "Avantree Slumber" in your device's Bluetooth menu.
NOTE: You'll need to adjust the volume on both the Slumber & your audio device to reach the lowest volume level.
Setting a Sleep Timer

FAQ
Below are some of the most common questions people have during setup.
Is the pillow washable?
Yes, you can wash the pillow by hand whenever necessary. Please take out the speakers before washing. When re-assembling, make sure that the main speakers are facing upwards. You can find more specific directions on re-assembling at avantree.com/support/slumber/install.
I turned the volume down as low as possible -- why can someone else still hear?
Make sure to adjust the volume on both your device and the Slumber in order to reach the lowest volume levels. If the sound is still leaking, you can consider resting your ear directly on top of the speaker and turning the volume down even further.
