Note: You will get the best result in calm water with a smooth turn
on the steering wheel independently of how the circle is
performed. When activated, you can stop the automatic compass
deviation at any time with the command C3.
3.1.3 Magnetic deviation
Magnetic variation. Maximum +/- 179.9°.
Easterly variation = no sign.
Westerly variation = minus ( - ) sign.
The local magnetic variation is usually printed in the sea chart.
1. Press ESC, to stop the transmission
2. If you press A? The current variation is displayed
3. Set the new variation in tens of degree (1 degree = 10)
Example 1. If you want 1.8 degree east enter the value A18
Example 2. If you want 5.5 degree west enter A-55
3.1.4 Compass misalignment correction
Compass transducer misalignment correction or the so called ”A-
fault”. Can be set between 000°and 359°. Allows 180° reversed
mounting if needed. Never mount the transducer in a 90° position
relative to the boats fore-aft line.
To check the transducer position, sail/drive your boat in a straight
line towards two visible objects in a line.
Maximum Misalignment. +/- 179.9°.
1. Press ESC, to stop the transmission
2. If you press D? The current variation is displayed
3. Set the new variation in tens of degree (1 degree = 10)
Example 1. If you want 1.8 degree enter the value D18
Example 2. If you want -5.5 degree enter D-55
3.1.5 Cancel earlier performed compass deviation
1. Press ESC, to stop the transmission
2. Press C0 to cancel the previous Autodeviation
