6. Continue slowly turning the boat until the controller beeps and displays the
DEVIATION screen. This indicates that the SPX system has completed the
deviation correction.
Note:
This screen shows the maximum deviation over 360° (not as an east/west value).
If the deviation figure exceeds 15°, the compass is being affected by ferrous objects
on your boat. You should move the compass to a better location. Higher deviation
figures are acceptable on steel boats.

Aligning compass heading

Once the deviation is displayed, press disp to move to the Align Heading
(ALIGN HDG) page, then:
1. Manually steer the boat on a steady course at a speed sufficient to hold the
course.
2. If you have a GPS connected to your SPX system:
• Increase the boat speed to more than 3 knots.
Press auto. The SPX system will then set the heading to agree with the COG
•
(course over ground) heading received from the GPS.
As many factors can cause a difference between heading and COG, you must fine-
tune the heading alignment to match the boat's steering compass (or a known transit
bearing). To do this:
1. Use -1, +1, -10 and +10 or the rotary control to adjust the displayed heading
until it matches the boat's steering compass (or a known transit bearing).
2. Hold down standby for 2 seconds to exit Seatrial calibration and save the new
compass settings.
