re 1992 base C4 LT1 4L60 coupe: Concerning the AM/FM Stereo System with CD, Delco-Bose (U1F) I've seen reference to a security code required to restore functions after the battery has been disconnected. Anyone have experience or knowledge about this?

One day my system simply stopped working. It has power but no functions. I'm wondering if it shut down after I was servicing the car with battery disconnected. A code and process would be a welcome fix - or reference to discussion about same.

Thanks all for any assist - rac

WVZR-1: The screen has no message, only the amber/gold backlight glow (same as center dash speedo) to indicate receiving power.
