[Elecraft] K2 Heil Pro-Set connection locks up keyboard

[TRBOAG at aol.com]

I have K2 s/n 0660 recently completed and seems to be working  ok.
Tried to use Heil Pro-Set and installed per instructions that came  with it 
from Elecraft.
When I plug in headset, display freezes and buttons on K2 do not  work. Seems 
like Pro-Set is loading control board PS or  ?
Regular Elecraft Hand Mike connected to same input works  fine.
Regards,
Tom
