How to Turn OFF – Proposal
Find the Bluetooth button on the speaker right side, and the Volume Down button on the lower left side.
You could turn this mode OFF by pressing and holding in the Volume Down (-) and Bluetooth buttons. Hold for about ten seconds, until the pilot lamp on the top blinks a few times.
