  • To stop all antenna motion as quickly as possible, push the red e-stop switch.
  • To release the e-stop, twist the knob clockwise.
  • During an emergency, disconnect all power sources.

    • “Local” — enable these jog controls, overriding the ACU.
    • “Slew” — jog buttons will move the antenna as its slew speed.
    • “Toggle” — sustain antenna motion* once started, instead of only moving while a jog button is depressed
  3. As needed, use the jog buttons to…
    • move “AZ” (clockwise or counterclockwise)
    • move “EL” (up or down)
    • move “POL” (clockwise or counterclockwise)

*Until it hits its limit or the operator presses the jog button(s) again.
