[Elecraft] K3 RF REF CAL Procedure

[Paul Christensen]

Trying to get my K3 to go into Reference Oscillator Calibrate routine using 
Option
#3 (temp compensation).  I have "Tech MD" enabled [ON], but I cannot toggle
out of "REF CAL" to get to "REF xxC."   It just stays on "REF CAL" 
regardless of
tapping the "1" button on the numeric keypad.  Latest K3 firmware is 
installed.   Ideas?
