System Monitoring And Adaptation; Compass Lock; Locking The Compass - Raymarine LIGHTHOUSE 3 Advanced Operation Instructions

The compass offset can be adjusted from the Pilot set-up menu: Homescreen > Settings > Autopilot
> Pilot set-up > Compass offset.
Important:
Do NOT rely on the reported heading until compass linearization and alignment is complete.

System monitoring and adaptation

To ensure optimum performance, after the initial linearization process is complete the EV continues
to monitor and adapt the compass linearization to suit current conditions.
If the conditions for linearization are less than ideal, the automatic linearization process temporarily
pauses until conditions improve again. The following conditions can cause the linearization process
to temporarily pause:
• Boat speed < 3 knots.
• Boat speed > 15 knots.
• Rate-of-turn is too slow.
• Significant magnetic interference is present.

Compass lock

Once you are satisfied with the compass accuracy, you can lock the setting to prevent the system
from completing a further automatic linearization in the future.
This feature is particularly useful for vessels in environments that are exposed to strong magnetic
disturbances on a regular basis (such as offshore wind farms or very busy rivers, for example). In
these situations it may be desirable to use the Compass lock feature to disable the continuous
linearization process, as the magnetic interference may build a heading error over time.
Note: The compass lock may be released at any time, to allow the compass continual monitoring
and adaptation to re-commence. This is particularly useful if planning a long voyage. The earth's
magnetic field will change significantly from one geographical location to another, and the
compass can continually compensate for the changes, ensuring you maintain accurate heading
data throughout the voyage.

Locking the compass

Follow the steps below to lock the compass linearization.
From the Pilot set-up menu: Homescreen > Settings > Autopilot > Pilot set-up.
1. Select the Compass Lock toggle option so that it is enabled (Green)..
The compass linearization is now locked and automatic linearization will no longer be performed.
6.2 Autopilot control
Your MFD can be integrated with an Evolution autopilot system and act as the autopilot's controller.
Please refer to the documentation supplied with your autopilot for details on installing and connecting
your autopilot to your MFD.
Autopilot control from your MFD can be enabled and disabled from the Autopilot tab in the Settings
menu: Homescreen > Settings > Autopilot > Pilot control.
