We've just bought a Humax Foxsat HD receiver from eBay. We are having problems setting the parental controls even after following closely the instructions in the manual. We set the Guidance Policy to 'Guidance Marked Content' but this makes no difference, there are no warnings on any channels for adult content. I noticed that the 'Age Limit' box in greyed out and presumed the previous owners settings were still on and decided to do a Factory Reset and start again. But the Parental Controls settings still won't work even when applied in the Settings menu as before. All programmes are still available without any warnings or PIN codes needed. Any advice please ? Thanks.
