SAFETY INSTRUCTIONS
WARNING
Do not open the equipment.
Only qualified personnel should work
inside the equipment.
Do not disassemble or modify the
equipment.
Fire,electrical shock or serious injury
can result.
Immediately turn off the power at
the switchboard if the equipment is
emitting smoke or fire.
Continued use of the equipment can
cause fire or electrical shock.Contact
a ONWA agent for service.
Use the proper fuse.
Use of a wrong fuse can damage the
equipment or cause fire.
Be sure the power supply is compatible with the equipment.
Incorrect power supply may cause the
equipment to overheat.
The useable temperature range for the antenna unit is -25 to 70 ; -15 to 55 for the display unit.
Use of the equipment out of those
ranges may damage the equipment.
Safety Instructions for the Operator Safety Instructions for the Installer
WARNINGDo not open the cover unless totallyfamiliar with electrical circuits andservice manual.
Improper handling can result in
electrical shock.
Turn off the power at the switchboardbefore beginning the installation.
Fire or electrical shock can result if the
power is left on.

FOREWORD
Thanks you for purchasing the ONWA KEC-30
Your equipment is designed and constructed to meet the rigorous demands of
the marine environment. However, no machine can perform its intended
function unless properly installed and maintained.
Please carefully read and follow the operation, installation and maintenance
procedures set forth in this manual.
We would appreciate feedback from you.
Thank you for considering and purchasing ONWA.
Electronic Fluxgate Compass.

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.
