Compass swing
You will need to turn your vessel in slow circles while the system
automatically makes adjustments to account for compass deviation.
Each 360-degree circle should take no less than two minutes, and
you should complete at least two circles.
1. Start moving vessel in slow even circles, then press
START .
2. Keep speed to below 2 knots. Watch the display to ensure your
turn rate is not too fast. If the message ‘Slow Down’ is displayed
reduce your rate of turn, this can be achieved by slowing down
and / or steering in a wider circle.
If a ’Slow Down’ message is displayed the current circle will
have to be repeated.
3. When the compass has been calibrated, a message will be
displayed showing the detected deviation. If this is more than
15 degrees you will need to abort the calibration process and
resite the compass further away from metal items, then repeat
the calibration process. If you still find a deviation of more than
15 degrees, contact your Raymarine dealer for advice. If the
deviation is within acceptable limits, press
CONTINUE .
You can cancel Seatrial calibration at any time by pressing
STANDBY .
Aligning compass to GPS
Note: Systems without a GPS will skip this section and go
straight to Manual compass alignment.
If your system has a GPS connected to your data network (SeaTalk,
SeaTalk
ng or NMEA), the autopilot is tuned to the GPS heading
while you steer to a known magnetic heading. This step provides a
rough alignment and minimizes the amount of compass fine tuning
required.
1. Steer the vessel on a steady course with minimal tide, increase
speed to more than 3 knots and press START to align the
compass to GPS.
2. Follow the on-screen instructions until the process completes,
press the CONTINUE button when it is available to begin
autolearn.
You can cancel Seatrial calibration at any time by pressing
STANDBY .
Aligning compass manually
Where no GPS is present manual alignment of the compass is
required.
1. Continue to steer on a steady course and use the Use +1 and
-1 buttons, or the ROTARY controller to adjust the heading
displayed until it matches the vessel’s compass reading.
2. When complete press CONTINUE to begin Autolearn .
