Important Safety Information
Operator Alertness and Responsibility
The console helps the operator to steer the vehicle, but the operator remains in charge
and must be alert and in complete control of the vehicle at all times. The operator is
ultimately responsible for safe operation of this equipment.
It is essential that safety requirements are met when operating the console and any of
its components. All operators and other relevant personnel must be advised of safety
requirements.
Electrical Safety
WARNING: Incorrectly connected power can cause severe injury and
damage to people or the equipment.
When working with electrical components, you must do the following:
Make sure the negative terminal of the battery is disconnected before doing any
welding on the vehicle.
Check that all power cables to system components are connected to the correct
polarity as marked. Please refer to the vehicle manual for safety information.
Check that equipment is grounded in accordance with installation instructions.

viii
Operation and Risk of Obstacles
The following list is not exhaustive or limited. To use the console for assisted steering
along a defined wayline, the operator must ensure that it is used:
Away from people and obstacles
Away from high voltage power lines or other overhead obstructions (identify any
clearance problems before activating the console)
On private property without public access
Within cleared fields
Off public roads or access ways.
Note that:
The operator needs to know the vehicle’s position and the field conditions at all
times.
The operator will need to respond if the GNSS satellite or differential correction
signal is lost momentarily.
The console cannot detect obstacles (people, livestock or other).
Only use the console in areas that are clear of obstacles and keep a proper
distance.
Steering needs to be disengaged for manual control if an obstacle appears in the
path or the vehicle moves away from the wayline.
On/Off and Manual Control
WARNING: Ensure the steering switch is Off to prevent unintentional
engagement of the assisted steering. When repairing or maintaining
the vehicle/implement, ensure the vehicle CANNOT be moved.
Disengage steering, apply brakes and remove keys.
The operator must ensure that the steering switch is Off (all LED indicators are off)
when assisted steering is not being used.
The operator must disengage assisted steering and use manual control if an obstacle is
in the line of travel or moves into the line of travel, or if the vehicle steers away from
the desired wayline.
To disengage assisted steering:
Turn the steering wheel a few degrees OR
Select the Disengage Auto Steering button on the console AND/OR
If using an external steering switch, disengage using the switch if the above
actions do not disengage assisted steering.

ix
Vehicle Shut Down Safety
Before leaving the vehicle, disengage assisted steering, disengage external steering
switch if this is being used, and remove the key from the key switch.
Using a Reference (Base) Station
WARNING: Do not move a reference station while in operation.
Moving an operating reference station can interfere with the
controlled steering of a system using the reference station. This could
result in personal injury or damage to property.
Operators and other affected personnel must be advised of the following safety
precautions.
Do not erect the reference station under or within the vicinity of high voltage
power lines.
When using the portable reference station, make sure that the tripod is securely
mounted.
To Get the Best Out of the Product
Back up data regularly. The console has large, but limited storage capacity. Use the
Diagnostics Mini-view to view capacity available. A warning screen displays if
storage is reaching its limit.
Be aware of file format compatibility. Discuss compatible formats with the dealer.

Introduction
Chapter 1 –
Correct auto steering tuning is required to ensure the vehicle
approaches and follows guidelines in a smooth and consistent manner.
Tuning should only be carried out if auto steering performance is
unsatisfactory.
Note: Tuning should be carried out in a clear area away from high
voltage power lines and large metal objects. Allow enough space to
drive in a straight line for a minimum of 100 meters and enough room
to drive in complete circles. Tuning should be carried out at a speed
matching the speed of the operations planned.
The following factors can affect the performance of the steering
system:
Tyre size and number
Implement size, shape and loading
Vehicle speed
Terrain and soil condition
Tuning the vehicle is a real world application that is best performed in
actual working conditions. For example:
On soft ground with the implement fitted and engaged in work.
Hydraulic fans running if it is a seeder.
For self-propelled sprayers; have boom folded out with half a tank
of water.
For windrower, combines etc, have the front fitted and machine
running.
All these factors can severely affect steering performance and tuning
ability.
Note: The steering response of each vehicle will behave in a slightly
different manner. Two vehicles of the same make and type may
require different settings for optimal performance.

The X14, X30 and ISO UT consoles are included in this guide.
Note: If using an X14 console, follow the instructions supplied for the
X30 console if X14 instructions are not supplied separately.
Note: If you are using an ISO UT console, the advanced tuning
settings are not accessible. The AES-25 wheel angle sensor is not
supported for ISO UT. Contact Topcon technical support for
assistance.
