Hi all,

I just unboxed my SV03 today and it’s fully assembled and still won’t turn on. I’ve tried multiple outlets and nothing seems to work. I’m using 120V outlets.

Thank you!

Edit: There is a red switch on the back of the power supply to switch between 115 and 230V. Should’ve paid more attention.
