Hitch Recognition
1. Turn on the touch pad.
2. Press the left and right buttons simultaneously (Fig. 6A/B).
3. All leveling jacks will retract first, then the landing gear will extend to raise the unit to the height where
the auto level sequence was started.
NOTE: If the auto level sequence was started with the front of the unit in a below-level condition, the Hitch
Recognition will not function and the LCD will display “Feature Disabled.” In order for the Hitch
Recognition feature to function, the auto level sequence MUST be started with the front of the unit
above level.

Homing Jacks
1. Introduce an error - disconnect one of the hall effect sensor wires at the controller.
2. Attempt to operate the jack that is associated with the sensor wire that was disconnected. The touch
pad screen will display an error for that jack.
3. Reconnect the hall effect sensor wire. Manually extend all jacks down a minimum of 6 inches.
4. 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.
5. The jacks are now “homed.”
NOTE: If the jacks do not retract, an error should display on the touch pad screen. This is typically caused by
wiring interruption.
NOTE: In order to "home" jacks, middle jacks MUST also be extended. Refer to Basic Jack Operation for
middle jack operation.

NOTE: If the AUTO LEVEL sequence does not perform as described, place the system in manual mode and
test that the jacks operate correctly by pushing their coordinating buttons on the touch pad; i.e.
FRONT button operates only the front jacks.
