Good day all,
I recently purchased a '96 960 w/ the SC811 radio. The radio is disabled and requiring a code. I located the code in the original owners notes and the code is six digits containing two zeros. The questions is how does one enter a zero input? I also own a early model '95 960 w/ the same radio and the code is only four digits. Did the increase the code length to six? One final qusetion, what does it mean when the display shows "rpt"? I see this after entering only the last four digits of the code.

Thanks to all in advance for any/all input.
