I believe there might should be 2 LEDS that represent the states in Binary (Red and Green) ( I know that is the case with the color change). Laser Up arrow will give you a thread feed advance of I believe 91mm? But either way you should see the LEDS flash through all 4 or 8 states (if off is a state, I can't remember). But look at the color change for reference.
