[Elecraft] K3S Power On / PTT

[Bob McGraw - K4TAX]

In this regard and while waiting on my new K3S to arrive,  I've read the 
manual several times.   These discussions then raise the question, "is 
there no Master Reset" that returns the radio to factory default 
values?   I may have overlooked this.   However the product not having a 
Master Reset I view is a major shortcoming of the product.

If its there, I'd specifically like to know more.
