Safety Information
TeeJet Technologies is not responsible for damage or physical harm caused by failure to adhere to the following safety requirements.
As the operator of the vehicle, you are responsible for its safe operation.
Assisted/Auto Steering is not designed to replace the vehicle’s operator.
Do not leave a vehicle while the Assisted/Auto Steering is engaged.
Be sure that the area around the vehicle is clear of people and obstacles before and during engagement.
The Assisted/Auto Steering is designed to support and improve efciency while working in the eld. The driver has full responsibility for the quality
and work related results.
Disengage Assisted/Auto Steering before operating on public roads or when not in use to prevent loss of vehicle control.
WARNING: PINCH POINT HAZARD! To prevent serious injury or death, avoid unsafe practice while manually operating hydraulic

Valve Test
The Valve Test veries if steering is directed correctly. It can also be
used to test the amount of time to steer the wheels from full left to full
right (lock to lock) for non-proportional valves.
For non-proportional valves, the amount of time for left-to-right or right-
to-left (lock to lock) will be established by mechanically adjusting oil
ow through the valve.
For a UniPilot ESM, the amount of time for left-to-right or right-to-left
(lock to lock) will be established by adjusting the Max Duty Cycle value.
For recommendations and factory settings for the FieldPilot or UniPilot
setup values, see chart on page 21.
1. Select Valve Test .
2. While the vehicle is moving in a slow forward motion, turn
the wheels all the way to the left.
3. Press RIGHT arrow .
4. Press the engage/disengage switch or foot switch to activate the
test. This will start a timer as well as turn the vehicle to the right.
WARNING! When using a UniPilot, the UniPilot will move the
steering wheel very quickly. Keep loose clothing, hair and
hands away from the steering wheel while preforming this test.
5. Press the engage/disengage switch or foot switch when the wheels
are all the way to the right. The time displayed is the lock to lock
time.
6. While the vehicle is moving in a slow forward motion, turn
the wheels all the way to the right.
7. Press LEFT arrow .
8. Press the engage/disengage switch or foot switch to activate the

TILT CORRECTION
When a Steering Control Module (SCM) or Tilt Gyro Module (TGM)
is present, Tilt Correction options will be available. The Tilt function
corrects the GPS signal to compensate for errors in the GPS position
while operating on sloped terrain.
NOTE: A mistake in the calibration process that results in a 1 degree
error in the Tilt reading from the SCM/TGM will result in a
2.0 in. / 5.1 cm error in guidance [on a machine that has
9.5 ft. / 2.9 m antenna height]. This potential error necessitates
that all reasonable care is taken to ensure that the system is
installed and calibrated correctly in order to produce accurate
Tilt measurement and machine guidance.
