Caution Item on Equipment
Caution on a high voltage inside.
A high 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.
Ensure 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 A 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.

Caution Item 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
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
irradiation. As International regulation says, electromagnetic waves less than
100 watt/m2 does 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.
Specified power density and distance from the radar (in accordance with the
provision as specified in IEC 60945)

Caution on Display unit
Do not push or scrub the surface of the Display unit with a pointed tip of a
hard matter (tool, tip of a pen, etc) Scars could be made.
Do not press the surface of the Display unit. Interference stripes or display
abnormality could occur.
Disposal of this radar
This radar shall be disposed according to the municipal regulations or rules.
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-2000A Series Break in procedure of stored radar
0093120007-00 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 length 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.

Introduction
Thank for your purchase of KODEN color LCD marine radar MDC-2000A Series.
The quality and endurance of a unit is well considered. For the best performance, read this Operation
Manual and operate a unit correctly and safely.
The main features of this unit are as follows.
 The high performance radar equipped with 10.4 inch display can be used for professional use.
 In the true trail function, as moving targets such as other ships are displayed being tailed and
stationary targets such as land are displayed being fixed, the moving targets and fixed targets can
be easily discriminated.
 Two screen images of different ranges can be displayed. If you set a near distance screen and a far
distance, you can navigate properly and grasp a situation.
 The automatic tracking function (ATA) is provided. The maximum 50 targets can be tracked. The
current motion of other ships can be grasped in a vector and numeral so that it helps your ship to
navigate safely. (Optional)
 By connecting the AIS receiver, the gathered information such as name, heading and speed of a
ship can be displayed. (Optional interface)
 With the adoption of a specific filter (AR coat), an image can be seen clearly, refusing sunshine. The
countermeasures against the reflection on the LCD screen and dew are provided.
 The RGB output for an external monitor is provided as standard equipment. The use of the external
monitor enables you to observe easily the radar screen at a location which is remote from a main
unit. (External monitor: Prepared by a customer)
 A video from a CCD camera can be displayed. The inside of a ship can be observed by a camera
installed at the engine room helps your ship navigate safely. (CCD camera: Prepared by a customer)
(CCD camera cable: Optional)
 With the adoption of the GAIN/STC rotary knob, the operability is enhanced.
 When flush-mounted, a unit can be installed or removed from the front of the unit.

Change the observation range with the [- RANGE +] key.
When pressing the [+] key, the observation range expands.
When pressing the [-] key, the enlarged surrounding around own ship can be observed.
To make it easier to observe the range you desire, change the range.
Example of display :
Long range : Far distance Middle range : Middle distance
Objects at far distance
can be covered.
Short range : Near distance
Objects near own ship
can be easily confirmed.

Example of gain adjustment:
: Too high gain
Noise is also displayed. Desired targets are
displayed.
Some targets are not
displayed.
: Optimum gain : Too low gain
1.7 Gain adjustment
The gain becomes high when rotating clockwise the knob and becomes low when rotating
counterclockwise the knob.
When the observation range is narrow or targets are crowded, reduce the gain so that
targets can be easily seen.
When the observation range is wide, if the gain is increased, it is effective.
But, due to noise increase, small targets become hard to be seen.
