LCD does not display self test option.

Assembled printer, powered on. get a message that printer has not been calibrated, please follow instructions from manual. Clicking knob get me to a temperature settings display that says printer is ready, and one additional click get me to a menu that has

Info screen


No SD Card

Load Filament

Twisting the selection knob does not advance to next choice it only takes be back to calibration message.

I know it needs calibration but, as it is a kit, the self test needs to be preformed from the calibration menu that I am unable to reach for some reason.

Any ideas?
