HELP ! Radio Code(s)

[OuterMongolia]

I hadn`t used the Transit ( 1999 LWB 190 ,) for a couple of days went out to do some minor jobs on it ! I thought I`d have the Radio on while cleaning the front out . I turned it on - nothing . Kept fiddling with it .Nothing but eventually comes up CODE _ _ _ _. I goes and gets manual ,goes to Audio manual for code . I put the code in shown at the front of the book in to the radio .No luck ! Eventually after ten times , Comes up a timer and a 30.00 minutes countdown . After it gets to 00.00 try again still no luck . (I thought perhaps I has got the 0 and the 8 mixed up as I wasn`t wearing my glasses!). I stopped as I was worried about being locked out entirely . Radio had been working well in the days prior to this ,BUT two or three days before kept cutting out or not coming on ,Radio and CD player. Do I have a power connection problems?Should I go to a Ford Dealership? .Thanks in advance for any help and advice!
