audio system issue on 2006 Honda Civic

I replaced my car's battery and now the audio system says I need to enter a code for it to work. I looked in the car's manual, but found nothing. What is this code?

its just an anti theft code.turn the car on,hold down the 1 and 6 buttons,turn the radio on and it will display an 8 digit code.call the dealer and give them the 8 digit code and they will give you the radios unlock code.
