Operating hints
Steering sense
When the pointer indicates an off course error, steer the vessel in the direction you
want the pointer to move.
Man overboard/reciprocal course
If the vessel is turned through 110° or more when the ST60+ Compass Instrument
is in lock mode, the ST60+ Compass Instrument automatically locks to the
reciprocal of the original course (180° from the original). The digital display shows
the reciprocal course and the pointer shows the course error from the reciprocal
course.
The reciprocal course function is reversible, so that a second similar turn would
lock onto the original locked course.
Note:
The Man overboard/reciprocal course feature is not available when operating in
Auto mode.
Note: * relies on external data.
