GHP 12 Installation Instructions 17
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.
You must perform the sea trial wizard while under motor, and not while
under sail.
Important Sea trial Wizard Considerations
Complete the sea trial wizard in calm water. Because the nature of calm
water is relative to the size and shape of your boat, before you begin the
sea trial wizard, you must drive your boat to a location where:
• Your boat does not rock while sitting still or moving very slowly.
• Your boat is not significantly affected by the wind.
While completing the Sea Trial Wizard in calm water, you must:
•
Keep the weight on your boat balanced. DO NOT move around
on the boat while completing any of the steps in the Sea Trial
Wizard .
• Keep the sails lowered.
• Keep the motor in 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. Start the sea trial wizard.
3. If necessary, configure the planing RPM (
page 17 ).
4. If necessary, configure the planing speed ( page 17 ).
5. If necessary, configure the high RPM limit ( page 17 ).
6. If necessary, configure the maximum speed ( page 17 ).
7. Calibrate the compass.
8. Perform the autotune procedure.
9. Set north.
10. If necessary, set the fine heading adjustment.
