NOTE: Configure tractor as needed, using ballast guidelines and install implement.

NOTE: Drive tractor approximately 3.2 km/h (2 mph) in level field, with no draft load and implement raised, to calibrate radar. A change in loading of tractor can cause angle of radar to change which requires recalibration of radar system.

NOTE: Radar will display true ground speed on corner post below 19.5 km/h. (12.7 mph) and wheel speed above 19.5 km/h. (12.7 mph).

Mark a straight-line course of 122 m (400 ft).

At starting point, press and hold distance touch switch (A) for 3 seconds. Display will show zero.

Configure tractor as needed. To avoid track slip, drive tractor with no draft load at approximately 3.2 km/h (2 mph) to the 122 m (400 ft) mark and stop.

NOTE: Do not backup if end point is exceeded. Return to starting point and repeat procedure.

Press percent slip touch switch (B) and distance touch switch (A) simultaneously. Display will show "End" if calibration was successful. If not, display will show "Err" and calibration should be performed again at a slightly faster speed, but less than 11.3 km/h (7 mph).
