Importing the Siemens security certificate
You can import the Siemens security certificate into your Internet options so that you won't
be prompted for security verification when you enter https://ww.xx.yy.zz in your Web
browser, where "ww.xx.yy.zz" is the device IP address. If you use an http:// URL and not an
https:// URL, then you do not need to download and install the certificate.

the Siemens security certificate to your PC. The procedure varies according to which Web
browser you use:
