Re: KX1 Kit -- VFO Tuning and Readout ??

On page 64, left column (Pushbutton Switch Function), in the middle of the page on the description of the BAND button (single tap).  The text reads:

     [BAND]      One tap shows frequency (MHz first, then kHz;     L
                      or U is added in LSB or USB modes).  Two quick taps
                      selects the next higher band.


I think it should read as follows to make it more clear:

     [BAND]      One tap shows frequency: first MHz, second KHz, third display frequency
                      with resolution dependent on setting by VFO tap (or double-tap).
                      ...and so on...

What threw me for a loop was that the third display looked to be something unusual
since I was not expecting it and I was confused as a result.  I now understand how this
works but when first confronted by the display of MHz, KHz, and so on I was not
expecting three different numbers.
