Delstat dsr 5500 gold

[meridium]

hello
I'm new in this business and am not sure I got to a right section.I've got DELSTAT receiver DSR 5500 Gold,which has "cardless mode".Can anybody explain how it works? Also found on the net a site,from which I downloaded an "upgrade tool" and "software". Is it safe to use it? Does it contain the necessary updated keys for viewing scrambled programs?
Thank you

one more question about DSR 5500 Gold - every time I switch it off(unplug from a socket or switch off by button) the settings return back to factory. Can I fix it?
Thank you
