    1. Turn off the freeze dryer using the power switch at the back.
    2. Open the Door and remove the Shelving Unit.
    3. Inspect the connector at the back of the Shelf, make sure it is securely connected to the Freeze Dryer.

    2. Navigate to the Functional Testing Screen.
    3. Locate the Tray Temperature readout and note what is displayed.
