When the fixed sensor initialization step is completed, a green circle with a check mark sign before the term "Complete" appears in the "Fixed Sensor Initialization" field. The fixed sensor initialization completed date will appear below the term "Complete". Refer to Illustration 104.Verifying 2D and 3D Guidance Accuracy
To verify the machine dimensions, use either two known good points or use a GNSS survey tool to measure points.
Park the machine on an even surface that has a clear view of the sky.
Press the Next key until the second text window appears that shows "Northing", "Easting", and "Elevation".
Verify that the GRADE display is set for "Bucket: Center".
Place the front linkage in the air and swing the machine 90+ degrees or track the machine forward approximately 1 m (3.3 ft) to ensure that the GNSS receivers have an RTK fixed position and location history.

With the bucket near the tracks, place the "Bucket: Center" focus point on the known location.Note: The known location may be replaced with a surveying rover except the linkage can obstruct a clear view of the sky and satellites without getting multi-path from signal reflections.
Note the values of the Northing, Easting, and Elevation from the GRADE display for the center focus point of the bucket.
Compare the values from the known point (or the surveyed point) and the values that are shown on the GRADE display. The values should be within two tenth of a foot.
Illustration 106 g06282401
Illustration 106 shows the Northing, Easting, and Elevation for the focus point of the bucket. The focus point is shown with the center selected.Note: The GRADE display rounds off the values. The survey tool will carry out the values to more digits. If the values are not within two tenth of a foot, then the calibration and measure-up process will need to be repeated.

Repeat Step 5 through Step 7 with a known (or surveyed) point near full reach of the front linkage.Note: Two known survey points may be used and will provide a good evaluation of the system but one known survey point may also be used if the machine position is moved to reflect the linkage positions shown.Function Checkout
Press the arrow keys until "Diagnostics" is highlightedNote: "Diagnostics" is always the last item in the list.
Press the "OK" key.A screen appears showing all the devices that are detected.
Verify that all the following components are found and configured:
