4.9 Self-diagnosis
The self-diagnosis function is a tool to verify that LNB is operating properly.
If, for instance, production data could not be downloaded because of a communication error in
the machine, this tool enables you to search for the problem.
When you click the start button of the self-diagnosis function, verification starts automatically,
and the indication lamp of the error-detected part turns red. The following table shows the
solutions to communication errors.
