AutoAdapt
(AUTOADAPT)
The patented AutoAdapt feature allows the to compensate
for heading errors at higher latitudes, which are caused by the
increasing dip of the earth’s magnetic field.
The increased dip has the effect of amplifying rudder response on
northerly headings in the northern hemisphere, and on southerly
headings in the southern hemisphere.
1. Set AutoAdapt to:
•
nth (north)
in the northern hemisphere
•
Sth (south)
in the southern hemisphere
2. You then need to enter your current latitude in the next setup
screen (
LATITUDE
), so that the can provide accurate
course keeping by automatically adjusting the rudder gain
depending on the heading.
Latitude
(LATITUDE)
The only displays this screen if you have set AutoAdapt to
nth
or
Sth
.
Use the
-1
and
+1
keys to set the value to your boat’s current latitude,
to the nearest degree.
Note: If valid latitude data is available via SeaTalk or NMEA, the
will use this data instead of the calibration value.
