If one or more self tests show fail results (for example: "minor" or "fatal") more detailed error codes
can be read from the phone with "Details" button. Error codes are shown in hexadecimal format, but
notice that all returned hexadecimal values are not necessarily useful in RF troubleshooting because
some of the self tests return also different kind of measurement information together with "real"
error codes. If self tests are not passed, please refer to following subchapters for detailed
troubleshooting information.
IMPORTANT!
In order to use these self-tests most efficiently, it is very important that the tests are performed in
certain order (or at least the error data is analyzed in this order). The tests are designed so that by
performing them in this order it is easy to find the problematic component without any redundant
checks. The following flowchart is based on that idea (i.e. if RFBUS fails, there is no need to spend time
wondering why there is no power at TX).
