Functional limitations

If the functional limitations or any behaviour that is de-
scribed in the WebUI Manual occur, it may be caused by
the settings of your web browser or additional security
tools that are installed on your PC (e.g. anti-virus software,
firewall or browser-protection add-ons).
In this case, you should include the IP address of your CCU3
into the exception list of your firewall or browser protection
(exceptions are made for the Windows firewall). Furthermo-
re, you should always call the IP address via the CCU3 (see
„7.2 Starting the WebUI user interface" on page 39).
