How to fix radio in my 96 Citroen ZX?

No computer or OBD port on these cars.

I recently had this very same issue. You must enter the CORRECT radio code using 1,2,3,4, buttons and then register the code, using the left tune button. It's the one with two arrows. You can enter any random number and finish by pressing the "5" button, the radio will come on and work but beeps and then turns off after a few minutes.
I hope this helps people in the future.

it will need to go onto the correct computer to code in your radio.
