Preface
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.

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.

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.

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.

Warning: To prevent electric shock, be sure to turn off the radar system power before
opening the cover of the Antenna unit.
For health safety reason, transmission is basically inhibited when antenna is not rotating.
However when transmission is required for any reason without antenna rotation, following procedure is
provided to do it.
Special Service Mode
1. Turn off the radar and remove the Antenna drive motor fuse according to Figure 5.3.
2. Turn on the radar at the Operation unit by pressing the POWER ON/OFF key while the OFF key is
pressed.
Keep pressing the OFF key until "NO ERROR DETECT" is displayed.
3. After preheating time of 3 minutes, press the STBY/TX key.
If the magnetron is already heated, transmission is possible after 10 seconds, when "NO ERROR
DETECT" indication disappears.

6.2 Regular service and cleaning up
Periodic inspection and cleaning is essential to keep the radar system in the good working order for the
life of the radar.
6.2.1 Monthly inspection
(1) Check whether there is any dirt or soot on the radiating part of the Antenna unit. If any, wipe it with
soft cloth soaked in water or soap detergent. Also make sure no cracks or coating material is on the
front radiation part of Antenna unit.
Never turn on the power of radar system under inspection.
(2) Wipe the radar display with cloth soaked in static electricity inhibitor if dirty. Avoid using a dry cloth
since it will generate static electricity resulting in the accumulation of dust.
