To use your Sound+Sleep Aquarius as a Bluetooth source for water sounds, turn on the Bluetooth output feature by pressing the Bluetooth button until the headset indicator is lit. The Blue headphone status light will flash. Then, turn on your external earbuds or speaker to receive Bluetooth audio. This will turn off the internal speaker. Note that connecting with an external earbuds or speaker can take a while.
If you are having trouble pairing your phone, the battery built into the Sound+Sleep Aquarius may be low. To recharge the battery, connect it to a USB power source and allow it to charge for four hours.
