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
0092655002-03 1
Preface MDC-5200/5500 Series
is discharged in a suitable manner when checking the inside of the antenna. Maintenance and
inspection should be conducted by qualified engineers only.
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.

Chapter 1 Prior to installation
1.1 Installation precautions
In order to obtain the maximum performance of radar systems, this radar system should be installed by
qualified engineers in charge of installation and maintenance. Installation procedures include the
following:
(1) Unpacking of components;
(2) Inspection of composition units, spare parts, accessories and installation materials;
(3) Checking of supply voltage and current capacity;
(4) Selection of the location for installation;
(5) Installation of the Antenna-Scanner unit;
(6) Installation of the Display unit;
(7) Attachment of accessories;
(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.

1.4.1 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) The orientation of the Display unit shall be such that the user is looking ahead, the lookout view is
not obscured and there is minimum ambient light on the display viewing surface.
(2) Choose the best location from humidity, spray, rain, and direct sunlight.
(3) Keep sufficient maintenance area. Especially sufficient space is required near the back panel
where cables are connected.
(4) Keep as far as possible from other radio devices.
(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.

3.1.1 Installation of the Antenna Scanner unit
The Antenna Scanner unit is equipped to orient the notch of the attachment to stern as shown in Figure
3.1. Installation in this way eases maintenance work. Also refer to the consideration on equipment
shown in 1.4.1.
(1) Four mounting holes 14 mm in diameter are located on the mounting platform with reference to
Figure 3.1.
(2) The Antenna Scanner unit is secured with four 12 mm stainless steel bolts contained in installation
material.

3.1.2 Mounting the Antenna
(1) Remove the protective cap on top of the Scanner unit rotational shaft.
(2) Remove four bolts tentatively fixed to the base of the antenna and install the Scanner unit to the
rotating base. Align the direction of antenna radiation side (KODEN –mark side) with the projection
mark on the rotating base.
(3) Fix the aerial with four bolts removed in step 2.
