Für das Update wird ein Micro-USB Datenkabel verwendet. Ertönt kein Ton beim Anstecken, so nutzt man wahrscheinlich ein Ladekabel. Bei der Lieferung liegt immer ein passendes Kabel dabei.

Der USB Anschluss am Display ist sehr klein und empfindlich. Hier bitte höchste Sorgfalt walten lassen.

Sobald das Display angesteckt ist, er scheint es im Updater. Danach klickt man auf „Upload“ und wählt die Hex-Datei aus. Das Update startet automatisch. Währenddessen das Display nicht abstecken und das Programm durchlaufen lassen.
