60
12.3.12 C41 (0.10 ARC)
Arrival Circle. Set the radius of the arrival circle, from 0,01 to 9,99
NM.
12.3.13 C42 (RDR). C43 (AP1). C44 (AP2)
These 3 calibration codes are reserved for the Nexus autopilot: .
12.3.14 C45 (Pilot SEA)

12.3.15 C46 (000 LGD)
Local geodetic datum. Used to set local geodetic datum for
the Nexus GPS antenna from the Multi Control instrument.
A list for geodetic datum is supplied with each Nexus GPS
antenna.
The antenna is factory set for local geodetic datum WGS-84.
12.3.16 C47 (OFF MAG)
(Available from Multi version 2.0)
(ON) = All headings and bearings will be magnetic.
(OFF) = All headings and bearings will be true.

12.4 12.4 Compass calibration
12.4.1 Automatic compass deviation compensation (Auto DEV)
(Auto DEV) is performed by driving the boat in a circle up to 1¼
turn, so that the magnetic deviation can be measured, and by that
lso compensated.
Select calibration code C33 (Auto DEV).
Drive the boat in a circle for 1 1/4 turn in calm water. When you
start the circle manoeuvre, press KEY.
The un-deviated compass course will be shown in the display as
you turn. Complete the circle up to 1 ¼ turn.
When the manoeuvre is ready, press KEY to store the deviation
value.
If the deviation is corrected (Auto DEV) will be displayed.
