[Elecraft] Lost sidetone

Has anyone lost the sidetone on the K2?  For some reason I don't have the tone on CW when I transmit, on CW in the test mode, nor do I have spot when I try to zero 
beat another station.  It was working fine then it was gone an hour later.  I check the tone and level settings and they are just as I left them.  Tone was at 600 Hz and 
level was at 32.  I changed the level but that did not bring back my sidetone.  

Does anyone have any ideas?
