How Do I Reset the OBC (On Board Computer) ?

[Rudybs2003]

I have a 1983 733i and the battery died. Since then MY OBC only led's just scans across the display. Can someone tell me how to reset the OBC?

Thanks in Advance

I think you just want to use the number buttons on the top row of buttons to set the time, then the date, etc. I'm assuming your computer is similar to the one in my '86 528e, which I can't remember too clearly now.
