Need code for Mondeo stereo ...please!?

Hi, I had to remove battery and as such the sereo has locked itself!
Can anyone be a good sport and let me know the unlocking code for it?

It is a Ford Mondeo, W reg (2000), stereo is typical Ford RDS EON Serial number is: M064071

I'm assuming the procedure is to simply enter the code by pressing the number buttons at the base of the stereo?

Many thanks!
