Restarting Calibration; Locking Compass Calibration; Multiple Data Sources (Mds) - Raymarine Lighthouse Sport 3.10 Series Advanced Operation Instructions

1. If the difference is within plus or minus 10°, then select the Compass offset field and adjust
until COG and heading values are the same, or
2. If the difference is greater than plus or minus 10° you can align your heading sensor to the COG,
reported by you GPS/GNSS, by selecting Align to GPS and following the onscreen instructions.

Restarting calibration

If you experience problems with your heading data or have had to relocate the EV-1 sensor then you
can restart the automatic calibration.
From the this display menu:
1. Select EVO set-up.
2. Select Restart calibration.
The maximum deviation will be reset and automatic calibration will commence once vessel speed
(3 to 15 knots) and turn circle ()at least 270° turn) conditions are met.

Locking compass calibration

The EV-1 sensor is designed to continually adjust its calibration settings in the background to
improve its accuracy.
If your vessel is regularly in environments with strong magnetic disturbances (e.g.: offshore wind
farms or busy rivers) it may be desirable to use the compass lock feature to prevent the continual
adjustment, as over time this may cause an error in reported heading.
To enable compass lock:
1. Select EVO set-up from the This display menu.
2. Select the Compass lock toggle switch so that it is enabled.
Note:
You can disable the calibration lock at anytime by disabling the Compass lock toggle switch.

4.8 Multiple data sources (MDS)

MDS is a Raymarine scheme for managing multiple sources of identical data types on any single
network (e.g.: in a MFD network you may have more than one source of GPS / GNSS position data).
The following data types can have a preferred source assigned to them:
• GPS Position
