Delta CC Radio

[nikovision]

The radio in my 96 A6 is not cooperating. At first, I took the radio out and replaced the burnt fuse. After that, I realized the radio was in Safe mode. The radio just displays SAFE with 2 little lines in the right corner. (Possibly meaning "2"?)

I looked in the manual for how to enter the code in and followed the exact procedure. Held the FM 1/2 button and the DX button at the same time. I held it in for a while waiting for 1000 to pop up, but it never did.

I then decided that the 2 lines means 2 so the person before tried entering the code in wrong twice before possibly. So I followed the directions of leaving the radio on for an hour. I did this 3 times and each time waited for the radio to power off. Each time I did this, I turn the radio back on with the 2 lines still there and the radio not letting me enter the codes in.

I have run out of ideas, any help would be appreciated.
