[Elecraft] KRX3 problem with front panel buttons

[Randy Hargenrader]

I installed a KRX3 and all is well with operating the front panel 
controls until you select the sub rx, then the press and hold functions 
don't work and the radio wants to scan when I turn the dial....

The K3 display begins a scan when I try to tune it to a precise freq 
that is a mult of 10 on 20m, ie 14260, 14270, 14300, etc. Also there is 
a lot of flicker on the last digit which I assume is the scanning 
process reflected on the display.

Does anyone have an idea of what I have over looked or perhaps even 
broken installing the subrx?

Thanks in advance...
