Garmin GHP Reactor Mechanical Installation Instructions Manual page 9

With the engine (or engines) running, compare the RPM
readings on the helm control with the tachometer (or
tachometers) on the dashboard of your boat.
If the RPM numbers do not align, there may be a problem
with the NMEA 2000 speed source or connection.
Reviewing the Results of the Dockside Wizard
The helm control displays the values you chose when you ran
the Dockside Wizard.
1
Examine the results of the Dockside Wizard.
2
Select any incorrect value, and select Select.
3
Correct the value.
4
Repeat steps 2–3 for all incorrect values.
5
When you are finished reviewing the values, select Done.
The Sea Trial Wizard
The Sea Trial Wizard configures the fundamental sensors on the
autopilot, and it is extremely important to complete the wizard in
conditions appropriate for your boat.
Important Sea Trial Wizard Considerations
The Sea Trial Wizard must be completed in calm water.
Because the nature of calm water is relative to the size and
shape of the boat, before you begin the Sea Trial Wizard, the
boat must be in an appropriate location:
• The boat must not rock while sitting still or moving very
slowly.
• The boat must not be significantly affected by the wind.
While completing the Sea Trial Wizard, observe these
considerations:
• Weight on the boat must remain balanced. While completing
any of the steps in the Sea Trial Wizard, do not move around
on the boat.
• On sailboats, the sails must be lowered.
• On sailboats, the motor must remain in a position that drives
the boat in a straight direction.
Performing the Sea Trial Wizard
1 Drive your boat to an open area of calm water.
2 Select Menu > Setup > Dealer Autopilot Configuration >
Wizards > Sea Trial Wizard.
3
If necessary, configure the planing RPM.
This step applies only to planing-hull power boats with the
speed source set to Tach - N2K or Proprietary.
4
If necessary, configure the planing speed.
This step applies only to planing-hull power boats with the
speed source set to GPS.
5
If necessary, configure the high RPM limit.
This step applies only to power boats with the speed source
set to Tach - N2K or Proprietary or GPS.
6
If necessary, configure the maximum speed.
This step applies only to power boats with the speed source
set to GPS.

Set north (Setting North) if GPS-heading information is
available, or set the fine heading adjustment

available.
Calibrating the Compass

Select an option:
• If you are performing this procedure as part of the Sea
Trial Wizard, select Begin, and continue to drive in a
straight line.

• If you are performing this procedure outside of the Sea
Trial Wizard, from the heading screen, select Menu >
Setup > Dealer Autopilot Configuration > Automated
Setup > Calibrate Compass > Begin.
2
Follow the directions on the helm control until calibration is
complete, taking care to keep the boat as steady and flat as
possible.
The boat should not list during calibration.
3
Select an option:
• If the calibration completes successfully, select Done.
• If the calibration is not successful, select Retry and repeat
steps 1 through 3.
When the calibration is complete, calibration values are
displayed. You can use these values to determine the quality of
the calibration procedure.
Compass-Calibration Values
After the compass calibration process is complete, you can
review the results provided on the helm control to determine the
successfulness of the calibration.
• Indicates the level of distortion of the Earth's magnetic
field at the mounting location.
• A value of 100 indicates the device experiences no
magnetic interference at the mounting location.
• If this value is low, you might need to move the CCU and
calibrate the compass again.
• A value of 100 is ideal, but it is not necessary for the
autopilot to function correctly. If the CCU is mounted in an
optimal location on your boat, you should continue
configuring the autopilot and evaluate the performance
again later.
Spin Quality: Represents the level of the boat during the
compass-calibration process.
• A value of 100 indicates the boat remained perfectly level
during compass calibration.
• If this value is low, you might need to calibrate the
compass again.
Performing the Autotune Procedure
Before you can begin this procedure, you must have a large
stretch of open water available.
1
Adjust the throttle so the boat travels at a typical cruising
speed that provides responsive steering.
2
Select an option:
• If you are performing this procedure as part of the Sea
Trial Wizard, select Begin, and continue to drive in a
straight line.
• If you are performing this procedure outside of the Sea
Trial Wizard, from the heading screen, select Menu >
Setup > Dealer Autopilot Configuration > Automated
Setup > Autotune > Begin.
The boat performs various zigzag motions while the Autotune
is in progress.
NOTE: During the Autotune procedure, the number of zigzag
cycles remaining counts down on the helm control. You can
stop the procedure at any time, but allowing the procedure to
complete on its own gives the best results .
3
After the procedure is finished, follow the on-screen
instructions.
4
Select an option:
• If the Autotune procedure is not successful, but you have
not reached maximum cruising speed, increase the speed
and repeat steps 1 through 3 until the Autotune
procedure completes successfully.
• If the Autotune procedure is not sucessful, and you have
reached maximum cruising speed, reduce your speed to
