Chapter 5: Customising the System
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 7, “Post Installation Procedures”.
Deviation Display (DEVIATION)
This 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 shows the current reported heading.
Note: You should always check the compass alignment after performing a
compass deviation correction (see “Post Installation Procedures”).
However, once the initial correction procedure has been performed,
you can make adjustments to the alignment as often as you wish,
without re-correcting your compass.
• Steer onto a known heading, and check the heading displayed.
• If required, adjust the heading value to match the known value, using
the +1, -1, +10 and -10 keys.
Pilot Type*
Displays the Pilot Type: sterndrive, displacement, semi-
displacement or planing.
Heading Mode (HDG)
Select either magnetic or true heading mode, using the +1 or -1 key.
When heading data is displayed in normal operation, the screen
indicates whether true or magnetic mode has been selected.
