[Elecraft] Lost display button function

[Peter]

Hi

I found a strange behavior on my K2/100
When pressing the button display I do hear a beep, but no change on the display
I do expect to get the voltage reading and the current, but got still the frq. display
A long press on display  for ALC/RF rthe info doesn't come up.

End up with a total reset (456) after reading the BFO settings

Then the display button works normal.

Is there a other way to reset those settings?
