For Your Safe Operation
Symbol used in this Operation 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.
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.
