Caution Item on Equipment

Caution on a high voltage inside.

Ahigh voltage, which may risk your life, is used. This high voltage remains

in the circuit after you have powered off switch. To prevent touching the

high voltage circuit inadvertently, the protective cover is provided to the

high voltage circuit and the high voltage caution label is affixed. Ensure to

power off switch for your safety and discharge the electricity remaining in

the capacitor before starting to check. An engineer authorized by our

company should inspect and maintain the circuit.

Be sure to switch off the power in the boat.

If the power switch is inadvertently powered on during work, you will be

electrified. To prevent such accident from occurring, ensure to switch off

the power in the boat and the power of equipment. Furthermore, it is safer

to hang the caution tag with description of [Under Work] near the power

switch of equipment.

Caution on dust

Inhaling dust may cause respiratory disease. When cleaning the inside of

equipment, be careful not to inhale dust. Wearing a safety mask is

recommended.

Caution on location of equipment

Do not install the equipment where it is excessively damp and suffers from

excessive water drops.

Caution on static electricity

The static electricity may be generated from the carpet on the floor in the

cabin or clothes made of synthetic fiber. The static electricity may destroy

the electronic parts on the circuit board. Handle the circuit board, taking

the suitable anti-static measures.

Prohibited matter

Any Display and Scanner unit combination other than specified in the

manual is prohibited and will void manufacturer’s warranty.

Caution Items on Handling

Caution on the rotating aerial

The radar antenna may start to rotate without notice. Please stand clear from

the antenna for your safety.

Caution on electromagnetic disturbance

The operating Antenna & Scanner unit radiates high-energy electromagnetic

wave. It may cause harmful effect for human body due to its continuous

radiation. As International regulation says, electromagnetic waves less than

100 watt/m2does not have a harmful effect on human bodies, but some kind of

medical devices such as heart pacemakers are sensitive even under the low

energy electromagnetic wave. Any personnel with such a device should keep

away from the electromagnetic wave generating position at all times.

Do not disassemble or modify. It may lead to trouble, fire, smoking or

electric shock. In case of trouble, contact our dealer or our company.

In case of smoke or fire, switch off the power in the boat and the power of

equipment. It may cause fire, electric shock or damage.

Caution on the remaining high voltage.

A high voltage may remain in the capacitor for several minutes after you

have powered off. Before inspecting inside, wait at least 5 minutes after

powering off or discharging the remaining electricity in an appropriate

manner. Then, start the work.

The information displayed in this unit is not provided directly for your

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

Use the specified fuse. If un-specified fuse is used, it may cause a fire,

smoke or damage.

MDC-5000/5200/5500/7000(P)/7900(P) Series Break in procedure of stored radar

0093855002-00 vii

Break in procedure of stored radar

Following procedure is recommended for “Break In” of the stored radar.

Otherwise the radar sometimes exhibits unstable transmitting operation

such as arcing at its initial operation after long period of storage and make

the operation more difficult.

1. Extend preheat time as long as possible (preferably 20 to 30

minutes).

2. Set the pulse width to the shortest one and start the operation.

When the operation in the shortest pulse is stable then go to

operation in longer pulse and repeat the similar step until the

operation reaches to the final pulse condition.

Disposal of used cell and this radar MDC-5000/5200/5500/7000(P)/7900(P) Serie

Disposal of used cells and this radar

Treatment of the used lithium ion cells

To dispose built-in lithium ion battery cells (CR2032) in this radar, insulate each terminal with scotch

tape, etc. and wrap in a plastic bag, etc.

The disposal and collection rules may be different depending on each municipal district. Obey the

directions of each district.

Disposal of this radar

This radar shall be disposed according to the municipal regulations or rules.

A high-energy density lithium ion battery cell is built in this radar.

Improper disposal of the lithium ion battery cell is discouraged as the cell

has possibility of short-circuiting. If it gets wet, generation of heat,

explosion or ignition may occur resulting in injury or fire.
