[Elecraft] KX3: Difficulty performing I.F. image (16 kHz) nulling

I am attempting to perform the opposite sideband and I.F. 
image nulling procedure on my KX3, per the app note (rev 
A8). I had no trouble performing the opposite-sideband 
nulling steps, but have run into a problem in the I.F. image 
(16 kHz) nulling procedure on page 5.

Step 7(a) on page 5 states that "you should hear a strong 
signal". This contradicts step 14 on page 2, which states 
"Note: If you are preparing to null the RX SHFT=8.0 I.F. 
image, you may not hear any signal at this time since the 
VFO is offset from the signal source by 16 kHz". In fact, I 
am *not* hearing any signal.

Is it safe to assume that step 7(a) on page 5 is incorrect, 
and that I can safely proceed without hearing any signal?

73,
