Safety Notices
OPERATOR SAFETY
Watch for the rotating antenna:
The radar antenna will start to rotate without notice. For your safety, keep away from
the area in the vicinity of the radar antenna.
Be aware of RF Radiation Hazard:
The active radar antenna radiates powerful RF energy. Continuous exposure to RF
energy may cause harmful effects to the human body. It also causes Cardiac
Pacemaker to malfunction. A person who uses a Cardiac Pacemaker should under no
circumstances be exposed to RF radiation.
Most countries accept that RF power density levels below 100 W/m2 cause no
significant RF hazard.

Dangerous HIGH voltage inside:
Life threatening high voltage is present in the antenna and display units. This high
voltage may be present even after the power switch has been turned off. The high
voltage circuits are provided with protection covers and warning labels to avoid
unintentional contact with these sections. For safety reasons, switch the power off

before accessing the internal circuitry and discharge any residual voltages in
capacitors by an appropriate method. Only qualified personnel should attempt these
maintenance procedures.
MAINTENANCE SAFETY
Beware of residual high voltages:
High voltages may remain in the capacitors and the anode cap on the Cathode Ray
Tube several minutes after you have turned the power switch off. Wait at least five
minutes or discharge them to ground before starting your inspection.
Make sure the main power supply is OFF:
To prevent an electrical injury due to erroneous power switching, make sure that the
main power supply and the system power switch are both OFF. Also attach a safety
label showing that service is in progress.
Avoid inhaling dust:
The dust could be a temporary health hazard. When cleaning inside of the equipment,
avoid inhaling the dust.
Avoid static electricity:
Take care not to damage the ESDs (Electrostatic Sensitive Devices) due to static
electricity from carpet and cloths.

Installation
4.1 Installation considerations
Qualified service personnel should perform the installation of the RA83/84/85/93/94/
95 series. The installation comprises the following operations.
(1) Unpacking each component of the system.
(2) Inspection of the exterior of each component unit and accessory.
(3) Checking the ship’s mains voltage and current capacity.
(4) Determining the site of installation
(5) Installing the Antenna Unit.
(6) Installing the Processor Unit
(7) Installing the accessory items
(8) Planning the cable routing and connections
(9) Commissioning
4.2 Unpacking each component of the system
Unpack your package and check if all of the items stated in the packing list are
contained in the package. If not, report this to the insurance agent for tracing missing
goods or refund.
4.3 Inspection of each component unit and accessories
Carefully check the exterior of each component unit for dents, damage, etc. Also
check the inside of component units for electrical and mechanical damage.
4.4 Setting the units
To achieve the best operational performance, the following factors must be
considered.
4.4.1 Antenna Unit
(1) The radar antenna should be mounted on the centerline of your ship where no
large obstacles interfere with the path of the radar beam.
(2) Location should be as high as possible, however, keep in mind that nearby objects
may be overlooked if mounted too high. Also note that the higher the antenna, the
higher the level of sea clutter.
(3) The mounting surface should be as flat as possible and approximately parallel
with the vessel’s water line.
(4) The antenna unit should be positioned forward of large structure and exhaust

OperationManual
stacks, to avoid causing blind sectors on the radar screen as well as
contamination from engine exhaust on the radar antenna aperture.
(5) Provide sufficient servicing space.
4.4.2 Processor and Operation Unit
(1) Select a location that provides good observation to radar screen and outside
environment.
(2) Locate the display so that it provides easy viewing from all likely operator’s
positions.
(3) Select a position safe and free of dampness, water spray, rain and direct sunlight.
(4) Provide enough space for servicing. Consider access to the rear panel for
connecting various cables.
(5) Position the processor unit as far as possible away from other radio equipment.
(6) Keep a safe distance from the magnetic compass: standard: 0.60 m, steering:
0.40 m.
4.5 Cable routing and connections
4.5.1 Antenna
(1) The cable connecting the antenna and display should be run separately away from
other cables such as, radio antenna feeders, power cables, etc. Under no
circumstances should it be in parallel arrangement with other cables. These
precautions are essential to avoid radio interference to/from other equipment
installed on the ship. If this is not possible, either cable set should be screened
with metal conduit or another form of shielding.
(2) Cable should be run as short as possible but be kept within the standard length to
achieve best radar performance.
(3) The copper braids of the cable must be grounded via a grounding stud in the
transceiver unit.
4.5.2 Processor Unit
(1) The Processor Unit must be grounded to the hull via a grounding stud at the rear
of the processor unit.

4.6 Installation procedure
Observe the following procedure for installing the Antenna unit and Processor unit.
4.6.1 Installing the Transceiver Unit
When mounting the unit, position the transceiver unit as shown, so that a notched part
of the transceiver base is directed towards the aft. This arrangement simplifies cable
fitting and servicing. Also take note of the precautions detailed in paragraph 4.4.1
when you attempt to install the antenna unit.
(1) Drill four fixing holes of 14 mm diameter on the fitting surface of a radar platform,
as shown in Figure 4.1.
(2) Fit the transceiver unit on the position and fix it using the 12 mm stainless bolts
prepared as installation materials.

arisen to change these settings use the following procedures. Resetting must be
carried out in the following order.
1. Manual GAIN setting
2. STC (Height) setting
3. Manual STC setting
When completed, be sure to record respective setting values in the
GAIN/SEA/HEIGHT sheet prepared in this paragraph.
4.7.3.1 Manual GAIN setting
(1) Press and hold the MODE key and turn the power on. When a beep is heard,
release the key.
(2) Transmit the radar when STBY is displayed on the screen.

sheet (GAIN/SEA/HEIGHT sheet, hereafter).
(8) Repeat the above procedure for all range scales, if required.
4.7.3.2 STC (Height) setting
The STC characteristic is more less subject to vary depending on the height of the
antenna from the sea surface. Resetting the STC may be needed according to the
circumstances of the respective vessels. To achieve the best result, this setting should
be carried out off shore. Use the following procedure to do.
(1) Set SEA, GAIN and RAIN control to manual mode.
(2) Set GAIN to 8, SEA to 0 and RAIN to 0, respectively. Make sure that the sea
clutter speckle is appropriately shown on the screen. If the speckle is too much
or too short on the display, adjust the GAIN control as appropriate.
(3) Select an appropriate range scale to permit the clutter speckle is shown within
the screen.
(4) Adjust the SEA control to reduce the sea clutter until some residual clutter
speckle is shown.
(5) Turn the SEA control either clockwise or counterclockwise to see the effect of the
STC. If the effect is uniform in both long and short ranges, the STC Height
selection is considered appropriate. In such a case when the short range sea
return is suppressed earlier that that of the long range or vice versa, use the
following procedure to correct.
(6) Go SYSTEM>SYSTEM SETUP>HEIGHT and display the HEIGHT index entry
window.
(7) Adjust the SEA control to see the tendency of the control. If the short-range
clutter return is suppressed in advance to the long range one, reduce the
HEIGHT value by pressing the Joystick downwards, and vice versa.
(8) Adjust the SEA control to confirm the effect. If the result is not satisfactory, repeat
the above procedure.
(9) Press the ENT key to fix the setting.
(10) The HEIGHT index is irrelevant to the range. If this setting cannot be performed
offshore, the HEIGHT index should be selected with reference to the actual
antenna height from the sea surface. Use the following criteria as reference.

4.8.2 Remote Display operation
A Processor Unit type RP100A can be used as a remote display. To use the display in
this configuration, use the following procedure.
4.8.2.1 Connecting the Remote Display
Connect the Master display (RP100A) and a Remote display (RP100A) with the
connecting cable CW-561 (10m) as shown in Figure 4.16.
4.8.2.2 Required set up
In the Slave display, set the status switch S1-6 on the Logic PCB (E47-700*) to ON.
CAUTION:
Do not connect the Antenna unit to the remote display. If do so,
the remote display may malfunction.
4.8.2.3 Possible operation on Remote Display
The remote display is configured to be slave to the master display in terms of
transmission control, transmit and standby. Except this function, the remote display
has all controls that the master does, such as, gain, STC, FTC, range scale change,
off-centering, changing mode of operation, VRM, EBL, fixed rings, etc.
In the following circumstances, the display presentation becomes abnormal but is not
fault.
(1) When the transmission is turned off, the slave screen is displayed with plural
coaxial video caused by non-updated video data.
(2) When the master display is set to short range and the remote display to long
range, the remote screen will be shown with coaxial radar picture caused by
higher transmission rate video being supplied from the master display.
(1) On the contrary, when the master display is set to long range and remote display
to short range, the remote display screen will be shown with stretched video
towards range. In a particular case, the radar video display will be shown
halfway due to slower transmission rate.
NOTE: To utilize the nav data, true bearing mode, true motion mode and EPA/ATA
functions in remote display, relevant sensor units such as, gyro compass, speed log
and GPS receiver must be connected.

APPENDIX 1: Interpretation of Radar Images
Factors that affect the radar detection range
Radar Horizon
The radar uses microwave energy that
travels in a straight line like light. Light is
reflected towards the surface of the earth
due to the temperature, humidity, and the
atmospheric pressure changes in the air.
This causes the visual range to extend
beyond the physical horizon. This is called
the optical horizon. Microwave has the same
effect and this is called the radar horizon.
Meanwhile, its wavelength is longer than
that of light. The radar visual range is
therefore longer than light by approximately
6%.

D=2.2(√H1 + √H2)
Sub-refraction
Sub-refraction
When cold air flows over a warm surface,
the microwave is bent upwards as shown in
the figure. This phenomenon is called
sub-refraction. As a result, the detectable
range may be reduced. This situation is
likely to occur in the Polar Regions, or in
warm current waters where cold air from the
Polar Regions flow over the sea surface.
Cold air
Warm air
Antenna
Detectable range is shortened
Earth
Super-refraction
When the air being warmed up in an inland
area flows over the cold sea, the microwave
is bent downwards. In this case, a
detectable radar range may increase. This
situation may occur produced in warm
coastal regions, and it becomes noticeable
as the temperature difference becomes
larger.
Super-refraction
Warm air
Cold air
Antenna
Detectable range is lengthened
Ducting
When two or more layers of different
temperature come into contact with one
another, the radar wave may be reflected
from the boundary surface where different
refraction indices exist. As a result, the
microwave propagates along the curvature
of the earth while being reflected on the
wave passage situated between the
interface and the surface of the earth. This
passage is called “Duct”, and an abnormal
propagation of the radio wave caused by the
duct is called “Ducting”. If the air layers with
mutually
different
temperature
or
atmospheric pressures are alternately
present along the different altitudes, radar
may be able to detect a target far beyond its
maximum detectable range.

Picture resolution
The picture resolution depends on the bearing and range discriminations that are
solely determined by the antenna horizontal beam width and the transmission pulse
length. These factors are defined in the following explanations and illustrations.
(1) Bearing discrimination
The bearing discrimination is defined as the minimum bearing where two targets of
the same distance are displayed as two independent images on the screen. The
bearing discrimination is determined by the aerial horizontal beam width.
The distance between two targets
in azimuth is shorter than the radar
beam width.
The distance between two targets
in azimuth is longer than the radar
beam width.
(2) Range discrimination
The range discrimination is defined as the minimum distance where two different
targets situated in line on the same bearing are shown separated. The range
discrimination is dependent on the transmission pulse length.
When the range between two targets is wider than the transmission pulse length.

situation around your own ship.

The buoy No.1 is not detected because the cape blocks it.
The echo of the large boat is painted similar to its actual profile because of short
distance.
The echo of a small boat is shown as a spot because it has a small echoing area.
The hill located on the starboard (in the bearings of 90 deg to 130 deg) has a deep forest
zone, and its echoing area is large. It is represented as wide spreading echoes on the
screen.
Since the sand beach on the port side is deep, but is not topographic. The echoes are
shown weak.
The windbreak forest produces strong echoes, and it is shown as massive echoes in
high contrast.
The echoes reflected from the sea surface change from time to time, depending on the
wind speed and direction．These echoes are shown as a group of spots.
False echoes
The operator should be fully aware of various false echoes caused by the radar
performance, terrain and structures on the land, as mentioned below.

(2) False echo caused by multiple echoes
True echo
When a boat passes near a large boat, radio waves
are repeatedly reflected between own boat and the
boat nearby, causing several echoes at regular
intervals to appear in the same bearing (Multiple
reflections). These false echoes produced by
multiple reflections are called multiple echoes. In this
case, the real target is the closest one. The multiple
echoes soon disappear when your boat moves from
the boat that caused the multiple reflections or, the
boat has changed her course. For this reason, the
true False
image can
easily
be identified.
(3)
echo
caused
by the side lobes
The radio beam emitted from a radar
antenna contains some residual smaller
beams on both sides of the main beam.
These components are called the side
lobes. A closely located target with high
reflectivity can be displayed as an arc
caused by the side lobes. To reduce these
false echoes, reduce the gain slightly or
apply A/C sea control.

(4) Shadow and dead angle
If the funnel, mast or other structures are located near a radar antenna, the radar beam will be blocked,
causing a shadow area where no object will be detected by the radar. The angle of the shadow is called the
dead angle. To avoid the shadow, the radar antenna position should be changed to a better place to
minimize this effect. If this is not possible, the operator should be aware this dead angle exists while
operating the radar.

Shadow caused by a mast
and other structures nearby
These echoes are not shown
caused by the dead angle
The dead angle changes according to the
dimensions and distance of the structures.
Height of antenna affects the short
range target detection. If the
antenna is mounted too high, the
radar beam may skip the target,
causing no echo detection. The
vertical beam width of the radar
antenna also affects the close range
detection.

APPENDIX 2: Receiving the Radar Beacons and SARTs
The X-band radar system is required to be capable of receiving signals emitted from a
Radar Beacon and a SART (Search and Rescue Transponder). To receive those
signals by the radar system, use the following procedures.
(1)
(2)
(3)
(4)
Set the range scale to 6 or 12 NM.
Turn off the Interference Rejection function from DISP/ECHO/IR menu item.
Refer to Para. 6.1.2 “IR (Interference Rejection).
In case the radar picture is obscured with too many echo signals, detune the
receiver a little for better observation.
When your vessel approaches the transmitting Radar Beacon or the SART, the
echoes will become blurred in an arc. For better observation of those signals,
adjust the Gain, Anti-clutter Sea and RAIN controls, as appropriate.
About SART
According to the GMDSS (Global Maritime Distress and Safety Systems) requirement,
the IMO/SOLAS class ships must be equipped with a SART. When a ship is in distress,
a signal will be automatically emitted from the SART so that other ships and/or
aircrafts can identify its location. When your ship carrying the X-band radar comes
within 8 miles of a ship in distress, the SART picks up the radar signal and responds to
it. The signal consists of 12 sweeps and is emitted in the frequency range of 9.2 GHz
through to 9.5 GHz. The SART has two sweep times that switch from slow sweep (7.5
us) to fast sweep (0.4 us) and vice versa, according to the distance. When the radar
receives this signal, a line of 12 dots, which is equally spaced at about 0.64 NM,
appears on the screen. The nearest blip of the SART indicates the location of the ship
in distress. When your vessel comes within 1 NM to the SART, a fast sweep signal is
displayed on the radar and a thin line connects the 12 blips.
Actual location of the ship carrying the SART
If your vessel is located at 1 NM or more away from the SART, the position at which
the first echo is displayed is 0.64 NM behind the actual SART position when the 12
SART echoes are identified. If your vessel comes within 1 NM from the SART, the fast
sweep signal is indicated. The position of this echo is displayed 150 meter beyond the
actual SART position.

6.7.1 Using the ATA
The ATA (Automatic Tracking Aid) unit is an optional PC Board that can be installed
into the processor unit. Using this function, up to ten targets can be manually acquired
and tracked automatically. All tracked target data is the same type as the EPA data,
and is shown on the right of the screen.
All operating procedures are also the same as that of the EPA function with one
exception i.e. no second plotting is needed in the ATA system.
Note: If the ATA system gets malfunctioned, the plotting system will switch to EPA
mode automatically.

(1) Sea clutter and weather clutter such as rain and snow may degrade the ATA tracking
capability. These clutter components should be appropriately reduced.
(2) Poor receiver sensitivity may also degrade the tracking capability.
(3) Faulty azimuth synchronization could be the cause of erratic vectors.
(4) Degraded bearing and speed data fed from external sensor devices also cause erratic
vectors.
If any of the errors stated above are detected, the following data provided by the ATA will be
erratic.
(1) The CPA and TCPA value.
(2) The target ship’s course and speed.
(3) The target ship’s bearing and distance.

Warning symbols
The following symbols are used in the EPA functions to notify the operator of a
high-risk target or invalid plotting. These symbols will blink when they are shown.
This is a CPA alarm symbol that appears when a displayed target is
predicted to infringe a predetermined CPA and/or TCPA range. It
blinks at an interval of 0.5 seconds. The data can be displayed by
assigning the target number.
This is a CPA alarm symbol that appears when the relevant target
number is assigned. The rest of the features are the same as above.
This symbol appears with audio alarm when the target is lost during
tracking. The on-screen error message “UNRELIABLE PLOT DATA” will
also appear on the screen. The symbol mark and audio-visual alarm will
be turned off automatically 15 seconds after first appearance of the

6.8 Operating the AIS
NOTE: To use this function, the optional AIS interface module (PCB based) must be
installed inside the processor unit and connected to an external AIS transponder. The
installation of the module must be performed by an authorized KODEN service
personnel.
Reference description: APPENDIX 1 Installation of AIS module, AIS-100, Chapter 4
Installation.
6.8.1 Outline of the AIS
The AIS interface module receives the other ship’s information sent from an external
AIS transponder and displays the AIS symbols and data. (NOTE: The AIS transponder
transmits own ship’s information at certain interval and also receives the navigational
information broadcast from ships located within the AIS reception coverage.
6.8.2 Setting the AIS to work
(1) In the DISP menu select AIS and select ON.

(2) In the RADAR menu select LIM (AIS range). Selecting the LIM range causes the
AIS symbols to be displayed within the LIM range.
(3) The AIS symbols are displayed on the target echoes, which are termed “activated
target.” The AIS interface can handle up to 20 targets for AIS processing. The
targets of 21 up to 40 are deemed to be “sleeping targets” or unprocessed targets,
causing the alarm message “Number of targets have exceeded the limit” to be
shown on the screen.
(4) To prevent potential dangerous targets from being unprocessed, always keep the
LIM range to allow a total number of activated targets to be within 20. To view the
AIS data of a specific activated target, set a target ID number in the RADAR menu
to an associated TARGET ID shown on the screen.

Sleeping Target
A target, which is not activated by the AIS user is termed “Sleeping Target.” The target
has no ID, vectors or ROT information, only showing the presence of a vessel with AIS
equipped.
Figure 6.10 Sleeping Target Symbol
Selected Target
A target selected by the AIS user is termed “Selected Target.” A target to be selected
can be Activated or Sleeping, whatever. Once selected, a dashed square is drawn
around the target and AIS data (MMSI, CPA, TCPA, COG and SOG) will be displayed
in the AIS data window.

Dangerous Target
If predicted CPA and TCPA values of an Activated Target are smaller than the one
being set up, the AIS target symbol will turn to a flashing bold symbol as shown below.
Figure 6.12 Alarm Target Symbol
Lost Target
A target that strays out of tracking is termed “Lost Target.” The lost symbol is
displayed flashing with a line drawn across. When an activated target changes to a
lost target, the buzzer sounds. When a sleeping target changes to a lost target, the
buzzer does not sound and the symbol will disappear automatically approx. 1 minute
later.
Figure 6.13 Lost Target Symbol
NOTE:
The radar vector (generated by EPA or ATA) and the AIS vector may differ in terms of
the vector length and its direction. This is not a fault. The radar vector is developed
based on the past target positions stored either by manual plotting (EPA) or automatic
tracking (ATA). Meanwhile, the AIS vector is generated from the navigation data sent
from the AIS transponder. The radar vectors take a certain time until they are fully
displayed, while the AIS vector is displayed as soon as the AIS data is received from
the AIS transponder.

9.1 Periodic inspections and cleaning
Periodic inspection and cleaning is essential to allow the radar set to work in good
order for a long period of time.
9.1.1 Monthly Check
(1) Check the antenna radiation surface for stains due to dirt soot. Wipe off the surface
using a soft cloth soaked with fresh water or soapsuds. Also make sure the radiating
surface of the aerial is free from residual paint or scratches.
Never turn the radar on while maintenance work is in process.
(2) If the display screen is dirty, clean the screen with a cloth soaked with anti-static
agent. Do not use a dry cloth as it causes static charging, which accumulates dust.
9.1.2 Yearly check
Check the motor brushes of the antenna unit every 2,000 working hours. Replace
them if the brushes are less than 6 mm in length.
Figure 9.1 Details of motor brushes
Figure 9.1 Criteria of the Motor Brush replacement
(1) Loosen the four fixing screws that fasten the front side cover and remove the cover.
The antenna motor will be found in the lower part in the antenna housing.
(2) Use a flat-blade screwdriver to loosen the motor brushes as shown in Figure 9.2..
(3) Insert a screwdriver into the groove provided on top of the brush and gently turn
the screwdriver counter clockwise. Make sure to remove both brushes.
(4) Install a new pair of brushes and reverse the procedure from step (3) to fix the
brushes.
Alarm: Make sure to turn off the equipment before attempting to reach inside of
the antenna unit. Failure to do so may lead to electrical shock.
