[Elecraft] K2

[Glenn Eisenbrandt]

OK, now it is my turn.  On page 60 of the K2 manual it says to tap 
 PRE/ATT  until  PRE  is turned  on.  No luck, I can tap it all day with 
no luck.  I have it set to 7000 and all that happens is that the carrot 
under the zeros moves each time I tap it. It also says that there should 
be some background sound. Nothing. The audio works as I will get a tone 
if I acrivate   SPOT.  
I proceeded with the  BFO  calibration and it went perfectly as well as 
the  VFO  .
I find nothing in the trouble shooting about this.  Now what?
