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).
