1) This is correct, the green harness has to be plugged in for the green led to blink. I will revised the user manual accordingly, Thank you.

2) On page 12.4, the manual did mention to set the "THRES" to fully CCW (8am). 3 o'clock is the wrong direction.

3) On page 17.8 did mention the usage of the gauge button.

Thanks for chiming in, #1 was very well spotted.
