Audio Systems: 99Honda Civic- Audio system reset, honda service center, time untill

Question
I bought a 99 Honda Civic LX. The guy who sold it to me said he had removed the batteries once and thats y the audio system is asking for a code. When i was trying out codes, it initially used to show CODE in the LCD display. Now..after i got the code from Honda service center (they told me a code after i gave the radio#), and i am entering it, its showing ERR1. did i mess up anything? how do i enter the code?

Answer
You get so many chances to entre the correct code, each time it doubles the lock out time untill on the final attempt it locks it out alltogether and you have to have it reset by the dealer. (or buy a decode programe from someone on Ebay, type this number into "search" 200016701970)
