Power button is Solid RedThe Power button is red & Load Mat button is white

If the power button is steady/solid red and the Load Mat button is white, this usually means that the machine needs a firmware update (How to?).

The software will take several moments to detect the firmware version on your machine and prompt you for any updates. Select the option to update the machine.

The Power button is red & no other button is lit

If the power button is steady/solid red and no other buttons are lit, this indicates it's a power related issue. We recommend trying another outlet or power strip.
