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.

Be sure that the power supply iscompatible with the voltage rating of the equipment.

Connection of an incorrect power

supply can cause fire or equipment

damage.

Use the proper fuse.

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.

1

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

Chinese and English menu display

Electronic Fluxgate Compass

It uses a fluxgate magnetic sensor in conjunction with a microprocessor to

display accurate heading.

The KEC-30 can correct magnetic deviation manually or automatically.

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.
