This is a brand new set. I tried to calibrate it and the app shows instructions for v1 which are not applicable to v2. The chessboard is in appartment for many days.
If the board still functions (touches, moves, board editor, etc) - then you are under or on a radio noise source. Typically it is a problem with the bulb or lamp, or a problem with a powered table. Relocating the board out of the noise solves it.
If the board is not functioning, then it is a faulty unit (and it can be intermittent - works sometimes and not others). Let us know if so - we can replace.
