[Elecraft] Can't access the DSP

[John Moore]

Hi guys, I need help.  I wanted to fine tune my filters in my K2 with  
DSP but I find I cannot access the DSP any longer.  The tap of  
DISPLAY no longer brings up the DSP.  I can access the CF1-4 but I  
can tell they are WAY off frequency.  Usually I turn the rig off and  
turn it on again and the resync is taken care of.  Not this time.  I  
removed the DSP and battery, defaulted the rig to factory. Still the  
CF filters are way off and DSP is not accessible.  The light diode  
flickers as it should upon restart of the rig.  Am I missing  
something obvious??  tnx John  NoGBR
