Using the Display

Every time you apply power to the cooling unit, the display interface initializes, causing the LEDs to

interface then scrolls automatically and continuously through screens of status information.

Press the up or down arrow key to interrupt the automatic scrolling and view a specific status screen. To

return to the scrolling status screens, press
