Flashing the display file
The display must be prepared before it is used for the first time. To do this, download the appropriate display firmware from the table and save it on a microSD card. The microSD card is inserted into the SD card slot of the display and the Brautomat is switched on. The flashing process starts automatically. The flash status is shown on the display. After completion, the Brauomat is switched off and the microSD card is removed. The microSD card is not required for normal operation.
