If it's your first time in a while, hopefully you look at ERSA and think, what's this AFIS business and give them a call and ask.
If that didn't happen, hopefully your composite chart gives you the CTAF frequency which you call up at say 10nm or whatever. Someone responds, says traffic is xxx (or no traffic), confirm you have received info xxx which you haven't because you didn't know about it. So they relay the info and advise you that there is a broadcast area 20nm to 8000'. And there it ends. It's a broadcast area in Class G airspace so you can't infringe it as you don't need a clearance.
Unlikely to be any follow up unless you were in someones immediate way, which at 10nm is generally unlikely, or you already knew about from monitoring the most appropriate frequency on the way.
