Radio Reset codes

Question

Describe your problem
Last week When I was wiping off the dash board of my 2001 Acura MDX, I accidentally messed up the radio. Now when I turn it on it ask for a code or it reads Error 1 or Error 2 all the way through Error 8. How do I find the code to unlock it.
Thank You
