The document provides instructions for setting up and calibrating the EZ-Steer Assisted Steering System that works with the CFX-750 touchscreen display. It includes setting up options like maximum angle, engage/disengage distances, override sensitivity, and more. Vehicle measurements also need to be entered like wheelbase, antenna height and offset. The calibration wizard guides the user through entering vehicle measurements, T2 roll calibration, and EZ-Steer system calibration to complete the setup.

Entering vehicle measurements For optimum guidance, you must take accurate vehicle measurements and enter them into the display. Note - Do not enter calibration numbers from EZ-Guide Plus or EZ-Steer T2 systems. This may cause very poor vehicle control, including swerves and/or large oscillations. To streamline the calibration process, you may want to take the vehicle measurements and record them for entry later on. The techniques for taking vehicle measurements are described below; to learn about implement measurements, see the User Guide. Before you take the measurements, position your vehicle as Note - If the EZ-Steer Setup button does not appear, tap Auto follows: Steer System Type and then select EZ-Steer for your controller. • Park the vehicle on level ground. 3

Engage status indicators Engaging the system Engage status Icon color Before you can engage the EZ-Steer system, you must: Ready to engage • open a field in the guidance screen • define an AB line • position the vehicle within the configured engage limits Engaged To engage the system: 1. Point the nose of the vehicle toward the guidance line and drive at operational speed. Cannot engage 2. Do one of the following: –– From the guidance screen, tap . –– Press the optional remote engage foot pedal. Antenna Disengaging the system CFX-750 display The EZ-Steer system automatically disengages when one of the following happens: • The vehicle is outside the configured engage limits. • You pause the system. EZ-Steer motor cable • GPS positions are lost. • You tap the Engage button on the guidance screen. CFX-750 power cable EZ-Steer motor You can manually disengage the EZ-Steer system by turning the steering wheel (this overrides the electric motor). Check this Antenna cable setting before you start using the system by engaging on a line and then turning the wheel until the system disengages. To adjust the amount of force required to disengage the system, change the CFX-750 power to Override Sensitivity in the Engage Options screen.
