Chapter 1: Introduction
Congratulations on the purchase of your Autohelm ST30 Compass.
The compass displays heading information directly from the fluxgate
compass or, if the unit is used as a repeater, via the SeaTalk bus using
data taken from another compass instrument or autopilot.
The compass can also be used as a steering indicator to maintain a
given course. Any helmsmans error, to port or starboard, is indicated by
a bargraph at the bottom of the display. This mode is known as “Lock”
mode.
