Preface

[Precaution for safety issues]

Precaution for operation

• Caution about rotating antenna:

The radar antenna may start rotating without notice. Please keep away from the antenna for your

safety.

• Caution about health risks caused by radio wave:

Powerful electromagnetic waves are emitted from the antenna during operation. These waves can

cause ill effects on human bodies when exposed to continuous radiation.

International criteria

Though the international regulation states that the electromagnetic waves with a high-frequency

2

power density of not more than 100 W/m

do not have an ill effect on human bodies, medical

devices such as a pace makers are sensitive to electromagnetic waves with minute electric power

and their operation may become unstable. In any event, any person with such a device must keep

away from electromagnetic sources.

• Caution about dangerous internal high voltage in the device:

High voltage that may cause risk of life is present in the Antenna unit and the Display unit of this radar.

This high voltage can remain in the circuit after the switch has been turned off. The high-voltage circuit

has a protective cover with a label “Caution against high voltage” so that no one will accidentally touch

it. Please ensure for your safety that the power switch is turned off and residual voltage in the capacitor

is discharged in a suitable manner when checking the inside of the antenna. Maintenance and

inspection should be conducted by qualified engineers only.

0092669006-05E 1

Preface MDC-7000P/7900P Series

Precautions for maintenance

• Caution against residual high voltage:

Capacitors used in the Display unit and the modulator circuit of the transmission unit may keep high

voltage for several minutes even after turning off power. The maintenance and inspection of this part

should be performed at least 5 minutes after powering off or applying the appropriate measure to

discharge the residual electrical charge.

• Keep inboard power source “Off”:

An electric shock is possible if the power switch is accidentally turned on during the maintenance

operation. In order to prevent such an occurrence, please ensure to disconnect the power breaker of

the onboard power source and the device. Furthermore, it is recommended to post the word-of-caution

tag shown to be in a "working state" near the power switch of the device.

• Caution against the dust:

Dust can temporarily cause distress to the respiratory system. Take care not to inhale dust when

cleaning the interior of the device. It is recommended you wear a safety mask.

• Measures against static electricity:

Static electricity occurring from carpet on the floor of the cabin, clothes made of synthetic fiber etc., may

damage some electronic parts on the printed circuit board. Please work on the printed circuit board only

after taking measures against static electricity.

• 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.

(8) Planning and implementation of cable laying and connection;

(9) Coordination after installation.

1.2 Unpacking of components

Unpack components and check that all items correspond with the description of the packing list. When

a discrepancy or damage has been found, please contact the transportation/insurance firm, and follow

procedures for searching for loss items and claim of expense.

1.3 Appearance verification of each unit and accessories

Please check the appearance of each unit carefully, confirm that they are dent and crack free.

Moreover, please also check the interior of each unit and confirm that there is no electric or

mechanical damage.

The illumination panel (back light) of the LCD module is made of glass. If the unit is dropped, damage

may occur. Since the presence of damage might not be found by checking of the appearance, please

confirm in the display after power on.

1.4 Selection of location for installation

In order to obtain the maximum performance of the units, it is necessary to install them in consideration

of matters as described below.

1.5 Cable wiring and interconnection

1.5.1 Antenna Scanner unit

(1) The connecting cable between the Antenna-Scanner unit and the Display unit should run apart

from any other radio antenna cable or power cables of the other devices. Do not lay the radar cable

in parallel to the sea surface together with other cables. These considerations are effective to

prevent random radio interference between systems. When these measures cannot be applied

because of space limitations, use metal pipes for each cable or other suitable ways to shield.

(2) In order to maximize the performance of the radar, the antenna cable and the power cable should

be as short as possible, and should be laid within the nominal length.

(3) Connect the shielded braided wire of the antenna cable to the grounding terminal inside the

Antenna unit

1.5.2 Display unit

(1) Ground the braided wire of a cable firmly with the cable clamp fixing screw to the back panel.

(2) The Display unit housing should be grounded to the ship ground by using the ground terminal of

the back panel.
