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
power density of not more than 100 W/m2 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.

Specified power density and distance from antennas (according to the
provision as specified in IEC 60945)

• 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.

0092669002-07 1

Preface MDC-7000/7900 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.

• Prohibited matter:

Any Display and Scanner unit combination other than specified in the manual is prohibited and will void
manufacturer’s warranty.

• 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.

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.

1.4.1 Antenna Scanner unit

(1) Blind sectors shall be kept to a minimum, and shall not be placed in an arc of the horizon from the

right ahead direction to 22.5° abaft the beam and especially shall avoid the right ahead direction
(relative bearing 000°). The installation of the antenna shall be in such a manner that the
performance of the radar system is not substantially degraded. The antenna shall be mounted
clear of any structure that may cause signal reflections, including other antenna and deck structure
or cargo. In addition, the height of the antenna shall take account of target detection performance
relating to range of first detection and target visibility in sea clutter.

(2) Keep the surface of the Antenna-Scanner unit platform horizontal as much as possible.
(3) The Antenna-Scanner unit should be installed in front of large objects or exhaust stack to prevent a

blind sector or the effects on the antenna by engine exhaust soot.
(4) Keep sufficient maintenance area.
(5) Keep safety distance from magnetic compass.

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.
