Hi Dale,
Remove all sources of power - batteries, if fitted and the mains adaptor from USB C - and leave the BB1 unpowered for 5 minutes or so. Plug the USB C adapter lead in and press POWER. Does the BB1 power up? Do the controls work?
If not please email us on - thebrennanb2 @ gmail . com - no spaces, with a brief description of the problem and we will get it sorted for you. Please let us know in the email, when and where you purchased the BB1 from and where in the World you are.
