1.9.1 Operation with and without Administrator Rights
With firmware version V3.xx (image version 3.11) and higher, the network analyzer
may be operated with or without administrator rights. Some administrative tasks (e.g. a
firmware update) do require administrator rights; refer to the detailed description of the
SETUP softkeys in chapter 4 of the operating manual.
In the default configuration, auto login is enabled, and an account with administrator
rights is active. This means that no password is required, and the full functionality of
the analyzer is available to any user. An additional user account without administrator
rights is pre-defined.
