A.
Press "FRONT" (Fig. 24H) to extend the front jacks (if required).
B.
Press "REAR" (Fig. 24K) to extend the rear jacks (if required).

Press and hold the retract button until all of the jacks begin to retract. The jacks will retract until they
reach the hard current limit.

The jacks are now “homed” and the special jack error code will be cleared.
NOTE:
If the jacks do not retract, an error should display on the touch pad screen. This is typically caused by
wiring interruption.
Zero Point Calibration
The “Zero Point” is the programmed point that the trailer will return to each time the Auto Level feature
is used. The “Zero Point” must be programmed prior to using the Auto Level feature to ensure the proper
operation of the system.
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. 24H) 5 times and then press and
release the “REAR” button (Fig. 24K) 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. 25).
5.
To set the current position as the zero point, press the “ENTER” button (Fig. 24C).
6.
LCD display will read “Zero point stability check” (Fig. 26).
7.
LCD display will read “Zero point set successfully” once process is complete (Fig. 27).
8.
The system will set this point as its level state and the touch pad will turn off.

Unhitching From Tow Vehicle

4.
Disconnect any wires, chains, or sway control that may be equipped
between the tow vehicle and the trailer. Unlatch the trailer coupler.
5.
Press and hold the “EXT” button (Fig. 28B) on the Power Tongue Jack
or press the "FRONT" button (Fig 24H) on the touch pad in standard
mode to extend the Power Tongue Jack until the footpad touches
the ground and the coupler clears the hitch ball.
6.
Once the coupler is clear of the hitch ball, move the tow vehicle a
safe distance away from the trailer.
