Check to see if you might have AUTO DETECT enabled:

   Auto Detect can be turned off if desired. Find the INP menu
   entry, the parameter, then tap DISPLAY to select ADET OFF.

With A DET enabled, if you happen to manage to close BOTH the DIT and 
DAH paddles at precisely the same time, the K2 'thinks' it has an 
external (non-paddle) keying device attached (as shown in the Fig 8-1 
illustration in the most recent K2 manual (page 95) and will generate 
to continuous output carrier (and sidetone) until the paddles are released.
