System Settings

Zero Point Calibration

The "Zero Point" is the programmed point that the travel 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 travel trailer. This is best achieved by placing a level in the
center of the travel 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 travel trailer is level, turn off the touch pad.
3.
With the touch pad off, press and release the "FRONT" button (Fig. 1H) five (5) times and then press
and release the "REAR" button (Fig. 1K) 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" (Fig. 15).
5.
To set the current position as the zero point, press the "ENTER" button (Fig. 1C).
6.
LCD display will read "Zero point stability check" (Fig. 16).
7. LCD display will read "Zero point set successfully" once process is complete (Fig. 17).
8.
The system will set this point as its level state and the touch pad will turn off.

Preventive Maintenance

1.
For optimum performance, the system requires full battery current and voltage. The battery must be
maintained at full capacity.
2.
Check the terminals and other connections at the battery, the controller, and the jacks for corrosion,
and loose or damaged connections.
3. Remove dirt and road debris from jacks as needed.
4.
If jacks are down for extended periods, it is recommended to spray exposed leveling jack rods with a
silicone lubricant every three months for protection. If the coach is located in a salty environment, it is
recommended to spray the rods every four to six weeks.
