[Elecraft] K3 - REF CAL Question

[Bud Semon N7CW]

I don't seem to be able to get my K3 to go from REF CAL to REF xxC.  Tapping
the 1 just changes from A to B.  I have the latest firmware and I can't find
anywhere I'm supposed to tell the firmware that I have the 1 ppm oscillator.
Can anyone tell me what I'm missing?

 

As long as I'm asking, I also can't figure out how to get the PA temp on the
display?  Is there a secret code?

 

Lastly, I have S/N 1041, which arrived and I built last week.  I don't have
anything to add to the building estimates provided by others - it went very
smoothly.  My only extra effort was to make myself slow down.  And this
weekend, I gave the radio a workout on 6M (425 QSOs in 181 grids - it was
nice to have some propagation).  It worked great - sensitivity seemed
adequate and the NB and NR were incredible.
