[sdiy] JH Frequency Shifter question

[JH.]

My Frequency Shifter can shift "thru Zero".
So, when you turn the knobs, or apply modulation voltages such that a shift 
goes down to zero, and further into the "negative" frequency range, what has 
been an "up-shifting" output, now becomes a "down-shifting" output, and vice 
versa. In order to indicate this on the front panel, you have the "Direction 
LED", abbreviated DirLED on the board connector.

What is the DirLD indicator on the JH FS-1A frequency shifter? I'd like to
label the dual led but cant' quite figure out what it is telling me.
