Compass deviation correction (SWING COMPASS)
The compass deviation correction option allows you to correct the
compass for deviating magnetic fields. The procedure must be
performed as the first item in your initial sea trial, and is described in
detail in Chapter 6, Post Installation Procedures.
Deviation display (DEVIATION)
The deviation screen shows the current deviation value, calculated
from the correction procedure (Swing Compass). You cannot edit
this value.
Heading alignment (ALIGN HDG)
The heading alignment screen is used to align the autopilot compass
with the ship’s compass.
• Steer your vessel onto a known heading.
• Adjust the displayed heading using the -1, +1, -10 and +10 keys.
• Check the autopilot display on various headings and adjust as
necessary.
Heading mode (HDG MAG/TRUE)

magnetic mode has been selected.

setting. Note that a rudder reference transducer is required for
