4.3 Lock Mode

This mode allows you to lock onto a heading and then steer your vessel

using the off-course bargraph to maintain the locked heading, which is

stored as the datum as soon as you engage lock mode.

AVERAGE

D1796-1

The off-course bargraph consists of 5 port and 5 starboard segments plus

the arrow head, which indicates a course error of 2°. The 5 segments

indicate course errors of 4°, 7°, 11°, 16°, and 22°.

Auto Lock

If AUTO is engaged from an Autohelm autopilot, the pilot will override the

ST30 compass locked heading. The small “AUTO” legend is displayed

during this mode to indicate that AUTOLOCK has been engaged.

Reciprocal Locked Heading

If your course error exceeds +/-- 110° the compass automatically selects

the reciprocal locked heading.

Please note...

If the ST30 Compass is being used with an autopilot, the reciprocal

heading feature is disabled.
