Zero Point Calibration
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 (Fig. 18G) 5 times and then press and
release the “REAR” button (Fig. 18J) 5 times.
4. The touch pad will flash and beep and the display will read “ZERO POINT CALIBRATION ENTER to set,
Power to Exit” (Fig. 19).
5. To set the current position as the zero point, press the “ENTER” button (Fig. 18C).
6. LCD display will read “Zero point stability check” (Fig. 20).
7. LCD display will read “Zero point set successfully” once process is complete (Fig. 21).
8. The system will set this point as its level state and the touch pad will turn off.

11. Push the “UP” arrow (Fig. 18A) to scroll to “Drop Front Jacks” option on LCD screen.
12. Red indicator lights (Fig. 22B) may come on, indicating the current disposition of the trailer. In this case,
the front and right side of the trailer are low.
13. Push “ENTER” (Fig. 18C). Both front jacks will go to ground and stop.
