If the joystick is jogged to either jog left, or jog right, and the central switch is pressed while in that position, the mode 1 LED will flash quickly, to indicate that the jog function has switched to jog ABC set point sub mode. In this sub mode, a jog left will move the ABC activation point to a lower MPG to allow the activation at this lower MPG. A jog right will move the activation point to a higher MPG point. To revert back to the jog ABC level, again press the central button while jogging either up or down, or simply tap out of mode 1, and then back into mode 1, as the level jog is the default for this mode.
