Heading sensor calibration
The built in heading sensor will need to be calibrated before use
to compensate for local magnetic fields on your vessel for accurate
chart with radar overlay.
Auto Calibrate mode
Before the heading sensor calibration is started, make sure that
there is enough open water around for the vessel to make multiple
full turns. The calibration should be done in calm sea conditions
and with minimal wind to obtain best results.
ADisconnect then reconnect the sensors NMEA 2000® cable.
BMake two consecutive turns of 360 degrees. The completion
of these two turns automatically activates the Auto Calibration
procedure.
CContinue with a smooth third turn and a quarter (of at least 390
degrees) within 2 to 5 minutes, to complete the calibration.
DCalibration should be complete. If the time is outside the limits,
the calibration is void and the radar overlay may not appear
accurate on your chart. Repeat steps A-D if calibration fails.

Calibration from a Multifunction display
Calibration can be performed from a compatible Multifunction
display, instrument display or autopilot controller. For more
information, refer to the documentation for your display unit.
Multiple heading sensors on the network
WARNING: Point-1 is a heading sensor and GPS antenna. By
default, Point-1 is a heading sensor if there are no other heading
sensors on the network. If there are two Point-1 units on the
network, only one can be a heading sensor, the other will function
as a GPS antenna. In this case, the Point-1 unit that is used as the
heading sensor must be set to instance ‘1’.
If there is a Point-1 unit and another heading sensor on the
network, such as Precison-9, the latter would be the heading
sensor by default.
If you have multiple Simrad® GS25 or B&G® ZG100 heading
sensors on the network, your MFD will only receive data from the
heading sensor set as the compass source in the system.

Heading sensor application
This sensor includes an electronic heading sensor to provide chart
stabilization, course over ground at low speeds, and overlay of
radar on charts.
Acceptable performance for the application.
A rate stabilized heading sensor such as
Precision-9 will provide the most robust
performance for demanding applications.
