Error, A7R, II

[sorgenfrigaard]

When I turn on the camera the following message appears: "Error - turn off and turn on the camera again".
So I do, and then it functions, when I turn it on again.
What is wrong?
Thanks ind advance.
Best wishes from Denmark

If the issue remains you will need to contact Sony for repair.
