When setting the zero point of Lippert Ground Control part # LC358590 you would want to have the slide outs in.

The “Zero Point” is the programmed point that the trailer will return
to each time the Auto Level feature is used.

Note: Prior to starting this procedure, double check all connections
on the controller, jacks, and touch pad.

1. In manual mode, run the jacks to level the trailer. This is best
achieved by placing a level in the center of the trailer and leveling
it both front to back and then side to side. (See “Basic Jack
Operation” for instructions on how to manually operate the system).
2. Once the trailer is level, turn off the touch pad.
3. With the touch pad off, press and release the “FRONT” button five (5) times and then press and release the “REAR” button five (5) times.
4. The touch pad will flash and beep and the display will read “ZERO
POINT CALIBRATION ENTER to set, Power to Exit”.
5. To set the current position as the zero point, press the “ENTER”
button.
6. LCD display will read “Zero point stability check”.
7. LCD display will read “Zero point set successfully” once process is
complete.
8. The system will set this point as its level state and the touch pad
will turn off.
