Can I turn Bluetooth off so my neighbors can't connect to my speakers or B1?

It’s not possible to completely disable Bluetooth, but when in Pair or Discovery mode (when the button is flashing) Pair mode will automatically turn off after 5 minutes.  Your speaker/B1 will be undiscoverable to unpaired devices but will remain visible to any device previously paired, so you can easily connect and disconnect from your phone, computer, or tablet.

If you want to pair more devices, you can wake up Bluetooth again by pressing the Pair button on the speaker or B1, which will then start flashing to indicate it's ready to pair.
