I’m not sure if you’ll find the answer to what you require in this thread, but most of the confusion on the 51C is acquiring advanced or admin settings, I think.  

Recover Default Settings
dEF represents recover default settings. The default value is N.
To access recover default settings, hold both the “+” and the “i” button for 2 s.
Press the “+” or the “-” button to choose Y or N again. N means that do not recover
default settings. Y means that recovers default settings.
When it is Y, hold the “i” button for 2 s to recover default settings; the display shows
DEF-00 at the same time, and then return to general display state.

If your looking for a list of default setting values, they should be different for every model of Sondors that use the 51C. To my knowledge I don’t believe those are published. Members have exchanged info about their settings in the thread,
