You can operate your SoundLink® speaker by using the control buttons located on the top of the speaker. The following is a description of the buttons.
Power: Press to turn the speaker on or off. Press and hold to check the battery status.
Aux: Press to select the external audio device connected to the Aux input.
Bluetooth®: Press to select the Bluetooth® source. The speaker attempts to connect to the last paired device.
If you want to use a different device, press and hold for 3 seconds to set the speaker to discoverable mode. This will allow pairing with another Bluetooth® device.
When a device is connected (paired), press to disconnect the paired device. The SoundLink® speaker then waits for another paired device to connect. If no device connects within 30 minutes, the speaker turns itself off.
Mute: Mutes sound from the speaker.
Volume up: press the plus button to increase the speaker's volume.
Volume down: Press the minus button to decrease the speaker volume.
Note: The source indicator on the front panel flashes once each time the plus or minus button is pressed. The indicator flashes twice when maximum or minimum volume is reached.
