Note on display zone 3:
During adaptation, various digits are displayed in display zone 3 which represent the relevant adaptation status. The most crucial factor is not the way in which the adaptation stage counter (display zone 3) behaves during the adaptation process, but that the specification "ADP OK" is displayed after adaptation in display zone 4.
If specification "ADP OK" is obtained:
- Press < button and perform next operation.
