Aligning The Compass Heading - Raymarine SmartPilot X-5R Drive Installation & Setup

Chapter 3: Commissioning & Setup
Note:
If necessary, you can quit the correction process by pressing standby or disp. If you then
want to repeat the deviation correction, return to the SWING COMPASS screen.
6. Continue slowly turning the boat until the controller beeps and displays the
DEVIATION screen. This indicates that the SPX-5R Drive system has completed
the deviation correction.
Note:
This screen shows the maximum deviation encountered over 360° (not as an east/west
value).
If the deviation value exceeds 15° the compass is being affected by ferrous objects on
your boat. If this occurs, move the compass to a better location. Higher deviation
figures are acceptable on steel boats.

Aligning the compass heading

Once the deviation is displayed, press
(ALIGN HDG), then:
1. Manually steer the boat on a steady course at a speed sufficient to hold that
course.
2. If you have a GPS connected to your SPX-5R Drive system:
i. Increase the boat speed to more than 3 knots.
ii. Press
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 so it matches the boat's steering compass (or a known
transit bearing). To do this:
-1, +1, -10
1. Use
steering compass (or a known transit bearing).
2. Hold down
compass settings.
