The zero point calibration is not a warranty issue. The inability to level the motorhome manually when withing a few degrees of level to start is a warranty issue.
This is an example of the procedure for setting the zero point calibration and may or may not apply directly to your system:
Zero Point Calibration
1. Set a carpenter’s level on the floor inside the unit and use the manual controls to manually level the
unit according to the carpenter’s level. Do this for front to back and side to side level.
2. Once the unit is level, press the “ON/OFF” button to turn off the interface.
3. With the interface turned off, press and release the “FRONT” button 10 times and then press and
release the “REAR” button 10 times. The interface will flash and beep, and the display should
read “ZERO POINT CALIBRATE”. To set this position in the memory, press “ENTER”.
4. The display should read “ZERO POINT STABILITY SUCCESSFULLY SET”
5. The Level Up system is now calibrated and ready to use.
