2001 Other Volkswagen Models Radio locked out

Computer problem
2001 Other Volkswagen Models 4 cyl Two Wheel Drive Automatic

My daughter hit the wrong buttons and now the radio screen is locked out and says "2 Safe" on it. I am pretty sure is a theft safe mode and I have the 4 digit number to press idon't know how to get to a reset mode.

How do I get it to reset please
