[Elecraft] odd k2 problem

[Hagood, Larry]

  Hello all,
I have completed my K2 and all seems fine until I press the "Rate/Lock"
button, When I tap it the LCD displays "nOt inSt" for about one sec, a relay
clicks then the main menu is displayed so I tap the "menu" button to exit
out of that and the voltage/ current is displayed so I tap the "display"
button to exit out of that and it goes back to the VFO but on a different
band than I started on??? 
   When I hold the "rate/lock" button it goes into the memory/ store mode.

I have done some of the simple things like visual inspection of components,
pads and traces on the front panel board, I've re-heated some of the related
pads, I've replaced the firmware 2.01f with 2.01h, I've checked continuity
of the switch and to pin 14 of the IC then to pin 10 of the RP. 

Thanks for any help.
