Volvo: Radio code, radio code, radio model

Question
How do I reset the radio code in my 1998 S70??? I had my battery changed and this message now comes up.

Answer
Rodney,
You will have to contact your dealer for the code. Supply the radio model, part number and serial number. Part and serial number on top of radio. Once you have the number when the radio is on it will say code, using the buttons put in that number and it will switch on.
