What code would I need to get my radio working again W reg renault scenic?

I had my renault megane scenic worked in in a garage for a fuel pump problem. When the car was returned to me i had 4 zeros in the radio window and it does not work. I have read in the forum how to enter the code but do not know the code.

Phillips 22DC461/62P
9022 214 61628
FD 11 99 29 8022300
BARCODE 7700 433 943 X609
