Adaptation
Individual functions are called up by entering the appropriate adaptation channel numbers (listed in the adaptation table).
NOTE:
- Using measuring value blocks 10,11, 12 and 15, the values that need to be transferred to the new instrument cluster can be read out before replacement.
- Adaptation channels 42-44 (see measuring value blocks 13 and 14) do not need to be transferred when replacing instrument cluster, because they are adjusted by the factory for each new instrument cluster
