6.2 Seatrial Calibration
When you have completed the dockside calibration, you must
complete the setup by taking the boat on a short seatrial to:
1. Calibrate the compass:
• complete the automatic deviation correction
• align the compass heading
2. Adjust the autopilot settings to suit your boat:
• automatically on Type 150G/400G autopilot systems
• manually on Type 150/400 (non-GyroPlus) and Type 100/300
autopilot systems
Seatrial safety
Note: You can return to hand steering at any time during the
seatrial by pressing standby.
You should only perform the initial seatrial:
• when you have successfully completed the dockside calibration
• in conditions of light wind and calm water, so you can assess
autopilot performance without the influence of strong winds or
large waves
• in waters that are clear of any obstructions, so the boat has plenty
of clear space to maneuver
Note: Before you start your seatrial, make sure you have switched on
any ancillary equipment – such as a GPS (providing course over
ground (COG), speed over ground (SOG) and latitude (LAT) data) or
a speed log (providing speed through the water). This information
will help the autopilot achieve its best performance.
CAUTION: EMC conformance
Always check the installation before going to sea to make sure
that it is not affected by radio transmissions, engine starting etc.
