Hello Siegfried,
Please take the small video for your power on the machine. If it cannot test the card completely, then it cannot do the self test. Since it can get the selftest result, we need to see if it is card is not inserted rightly, or card is read but not show or card problem or something else. We need to see the power on photos then decide.

Dear hector,

There is no much difference between them. The card so22-b and so22-c have the same software. The difference is that the GM software of so22-b has more language version to choose.
