Warning to everyone: DO NOT TRY THIS, YOU WILL LOSE CW TOO!!

I had CW working on 80m this morning. Now I read this post so I thought "I
will go to 40m and try to tap M1-M4 in LSB mode and see what happens" and I
duly noted that I got no "NO DVR" message, but the filter bandwidths did not
change. Then I went to CW and foun d that the filter center frequency is set
to 0Hz and it cannot be moved. Changing mode or band, pressing NOR, or
switching off the K3 and switching back on again do not clear this. I cannot
shift the CW center frequency from 0.00!! :(

I don't have time to try reloading firmware so I will wait for someone to
suggest a fix.
