Pictograms used in this Service Manual

The following pictograms are used in this manual. The meaning of each symbols shall be well

understood and the maintenance and inspection shall be carried out.

Symbol Meaning

Mark for warning

This mark denotes that there is a risk of death or serious injury when

dealt with incorrectly.

Mark for danger of high voltage

This mark denotes that there is a risk of death or serious injury due to

electric shock when dealt with incorrectly.

Mark for caution

This mark denotes that there is a risk of slight injury or damages of

devices when dealt with incorrectly.

Mark for prohibition

This mark denotes prohibition of specified conducts. Description of the

prohibition is displayed near the mark.

Precautions on equipment

Be careful of high voltage inside

High voltage, which may risk you life, is used. This high voltage may

remain in the circuit even after the power is switched off. To prevent

contact with the high voltage circuits accidentally, a protective cover or

the label with this mark is provided on the high voltage circuit. When the

inside is to be checked, ensure to switch off the power and to discharge

the residual voltage for safety. An engineer authorized by Koden shall

carry out the inspection and maintenance works.

Power off in the boat

An accidental power-on during works may result in worker’s

electrification. To prevent such accident in advance, ensure that power

in the boat and on the equipment are switched off. Furthermore, it is

safer to hang a caution tag saying “Under work” near the power switch

of equipment.

Be careful of dust

Inhaled dust may cause respiratory affection. At the time of cleaning the

inside of equipment, be careful not to inhale dust. Wearing a safety

mask is recommended.

Caution on location of installment

The equipment shall not be installed at locations which are excessively

damp and suffers from water drops. Otherwise, dew condensation may

occur inside the display screen, and corrosion may occur inside the unit

box.

Measures against static electricity

Static electricity may be generated from the carpet on the floor in the

cabin or clothes made of synthetic fiber, and it may destroy the

electronic components on circuit boards. The circuit boards shall be

handled with appropriate measures against static electricity.

Caution at installation o

transduce

Transducer shall be installed at locations where there is no effect by

bubble and noise. Bubble and noise may seriously degrade the

performance of this equipment.

Precautions on handling

No disassembly or modification of this equipment is allowed. It may lead

to failure, firing, smoking or electric shock. In case of failure, please

contact Koden’s dealers or Koden.

In case of smoking or firing, switch off the power in the boat and of this

equipment. It may lead to firing, electric shock or damages.

Be careful of residual high voltage

High voltage may remain in capacitors for several minutes after

switching off the power. Before inspection of the inside, please wait at

least 5 minutes after switching off or discharge the residual electricity in

an appropriate manner. Then, start the work.

The information displayed on this equipment is not intended to use for

your navigation. For your navigation, be sure to see the specified

materials.

Please use the specified fuses. If un-specified fuses are used, they may

cause firing, smoking or damages.

Be sure to submerge the transducer in water before transmission. If

not, it may be damaged.

KGC-222 Introduction

0093822202-01 vii

Introduction

KGC-222 is a GPS compass.

Through the use of GPS satellites, it outputs the heading of vessel with a high degree of

accuracy by calibrating the phase difference of two GPS antennas.

The main features of this unit are as follows:

KGC-222 consists of two main components, Display and Antenna.

Display unit has processor, receiver and LCD display built-in.

KGC-222 has internal electronic compass as backup sensor.

This enables the backup sensor to output heading even if the GPS signals are interrupted

in such case as the vessel passing under a bridge.

KGC-222 can also output pitch / roll and heaving data.

When KGC-222 is used with an echo sounder with heaving compensation function, you

can obtain stable sea bottom without effect from heaves and waves.

It has 3 heading data output ports. Up to 5 ports will be available with connecting an

optional junction box.
