My MaxiTPMS TS408 is locked up. I scanned tire 1, continued to scan tire 2 and nothing happened. The little red wave stopped moving and now the TS408 is locked up. It seems none of the buttons work. Pushed, pushed and held both the (N) = cancel and the power off button. Nothing happens, the screen is froze on the first tire scan and the second tire trying to scan. I can not cancel or turn off the scanner. The picture shows the screen it is stuck on.
