8753: setting internal error correction coefficients

I am trying to upload a set of error correction coefficients to an 8753ES.

There is an example of how to do this in the manual (5B: pp 7-81 to 7-83), but I can't seem to adapt the code there to my situation.

I first send the CALIFUL2 command. Then I send twelve INPUCALxx commands with the error parameter data and finally I send a SAVC command.

The VNA complains when it receives the SAVC (error message: 063  "CAUTION: CALIBRATION REQUIRED").

What have I done wrong? The example in the manual does not seem to require anything else.
