The KEC-30 is a designed with ONWA`s advanced
LCD high definition display technology. This compass a wide range
of applications for any type of ships
The main features are
Perfect for use as heading sensor for Radar/ARPA, AIS, ECDIS,
scanning sonar
There are no mechanical parts such as gimbals or rotating motor, thus the
compass is free from routine maintenance

In the menu select and press [ENT] key.
The following window appears:
The compass has been calibrated during manufacture. This calibration will be
satisfactory for almost all installations. If you have a steel vessel, or some
other factor which causes the compass to perform poorly, the calibration
procedure will adjust compass characteristics to compensate.
The calibration should only be done if the compass is known to be inaccurate.
If the KEC-30 display as constant offset (e.g. the compass reads 3 degrees
high on all bearings), simply rotate the Fluxgate Sensor case to align
bearings with the ships compass. It is not necessary to re-calibrate the
compass as described below.
If the KEC-30 has inconsistent variation on different headings, the following
calibration procedure can be carried out. This procedure should only be done
in calm waters with adequate sea room.
