MULTI CONTROL
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 a press on CLEAR.
12.4.2 Automatic compass deviation check (Auto CHK)
(Auto CHK) is done by driving the boat in a circle up to 1 ¼ turn, after (Auto DEV) is performed. The result will be compared with (Auto DEV). If the deviation is less than 1,5*, the average value from the comparison between (Auto DEV) and (Auto CHK) will be stored.
If the check is OK, (Auto CHK) will be displayed.
If not an error message will be displayed.
Select automatic compass check (Auto CHK), press SET and repeat the same circle manoeuvre as described in the (Auto DEV) routine.
Note: As soon as you place any kind of ferrous items close to the compass, the (Auto DEV) / (Auto CHK) routines should be repeated. So if you have packed your boat for the vacation, think about where you place ferrous items in relation to the compass transducer.
12.4.3Cancel earlier performed compass deviation (Auto CLR)
To cancel earlier (Auto DEV), press SET.
12.4.4Compass misalignment correction (Adj)
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
To check the transducer position, sail/drive your boat in a straight line towards two visible objects in a line. If the actual heading taken from the sea chart is 330° and the compass displays 335°, then set calibration code C36 value to 360° - 5° = 355°.
