Zero Point Calibration
The “Zero Point” is the programmed point that the unit 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. Manually run the jacks to level the unit. This is best achieved by placing a level in the center of the unit
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 unit is level, turn off the touch pad.
3. With the touch pad off, press and release the “FRONT” button (Fig. 1G) five (5) times and then press
and release the “REAR” button (Fig. 1J) 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. 7).
5. To set the current position as the zero point, press the “ENTER” button (Fig. 1C).
