──ABOUT YOUR SAFETY──
Cautions for high voltage
High voltages from hundreds volts to tens of thousands volts are to be applied to the
electronic equipment such radio and radar devices. You do not face any danger during
normal operation, but sufficient cares are required for maintenance, inspection and
adjustment of their internal components. (Authorized maintenance personnel alone are
permitted to implement maintenance, check-ups or adjustment of internal components.)
High voltages of tens of thousands volts are so dangerous as to bring an instantaneous
death from electric shock, but even voltages of hundreds volts may sometimes lead to a
death from electric shock. To prevent such an accident, make it a rule to turn off the
power button, discharge capacitors with a wire surely earthed on an end and make sure
that internal parts are no longer charged before you touch any parts inside these devices.
At the time, wearing dry cotton gloves ensures you further to prevent such danger. It is
also a necessary caution to put one of your hands in the pocket and not to use your both
hands at the same time.
It is also important to select a stable foothold always to prevent additional injuries once
you were shocked by electricity. If you were injured from electric shock, disinfect the
burn sufficiently and get it taken care of promptly.
What to do in case of electric shock
When finding a victim of electric shock, turn off the power source and earth the circuit
immediately. If it is impossible to turn off the circuit, move the victim away promptly
using insulators such as dry wood plate and cloth without touching the victim directly.
In case of electric shock, breathing may stop suddenly if current flows to the respiration
center in the brain. If the shock is not so strong, artificial respiration may recover
breathing. When shocked by electricity, the victim will come to look very bad with weak
pulse or without beating, resulting in unconsciousness and rigidity.
FIRST AID TREATMENTS
☆ First-aid treatments
As far as the victim of electric shock is not in dangerous condition, do not move him and practice
artificial respiration on him immediately. Once started, it should be continued rhythmically.
（1） Do not touch the victim confusedly as a result of the accident, but the rescuer may also get
an electric shock.
（2） Turn off the power source calmly and certainly and move the victim away quietly from the
electric line.
（3） Call a physician or ambulance immediately or ask someone to call a doctor.
（4） Lay the victim on his back and loosen his necktie, clothes, belt, etc.
（5） a. Examine the victim's pulse.
b. Examine his heartbeat bringing your ear close to his heart.
c. Examine his breathing bringing the back of your hand or your face close
d. Check the size of the pupils of his eyes
（6） Open the victim's mouth and take out artificial teeth, cigarette or chewing gum if any.
Keep his mouth open, stretch his tongue and insert a towel or the like in his mouth to
prevent the tongue from suffocating. (If it is hard to open his mouth due to set teeth, open it
with a screwdriver and insert a towel in this mouth.)
（7） Then, wipe his mouth so that foaming mucus does not accumulate inside.
☆When pulse is beating but breathing has stopped
(1)
Tilt the victim's head back as far as this face looks back. (A pillow may be inserted under his
neck.)
(2)
Push his jaw upward to open his throat wide (to spread his airway).
(3)
Pinch the victim's nostrils and take a deep breath, block his mouth completely with yours
and blow into his mouth strongly. Take a deep breath again and blow into his mouth.
Continue this 10 to 15 times a minute (blocking his nostrils).
(4)
Carefully watch that he has recovered his natural breathing and stop practicing artificial
respiration.
(5)
If it is difficult to open the victim's mouth, insert a rubber or vinyl tube into one of his
nostrils and blow into it blocking the other nostril and his mouth completely.
(6)
When the victim recovers consciousness, he may try to stand up suddenly, but let him lie
calmly and serve him with a cup of hot coffee or tea to keep him warm and quiet. (Never give
him alcoholic drinks.)
Method of mouth-to-mouth respiration by raising head
①
(1)
Raise the victim's head. Support his
forehead with one of your hand and his
neck with the other hand. → ①
When you tilt his head backward, the
victim, in most cases, opens his mouth to
the air. This makes mouth-to-mouth
respiration easy.
(2)
②
Cover his mouth as widely as possible
with yours and press your cheek against
his nose → ② , or, pinch his nostrils
with your fingers to prevent air from
leaking. → ③
(3)
③
Blow into his lungs.
Continue blowing into his mouth until his
breast swells. Blow into his mouth as
quickly as possible for the first 10 times.
Fig.1 Mouth-to-mouth respiration
☆When both pulse and breathing have stopped
When no pulse has come not to be felt, his pupils are open and no heartbeat is heard, cardiac
arrest is supposed to have occurred and artificial respiration must be performed.
(1)
Place your both hands, one hand on the other, on the lower one third area of his breastbone
and compress his breast with your elbows applying your weight on his breast so that it is
dented about 2cm (repeat compressing his breast 50 times or so a minute).
(Cardiac massage)
(2)
In case of one rescuer,
Repeat cardiac massages about 15 times and blow into his mouth 2 times quickly, and repeat
this combination.
In case of two rescuers,
One person repeats cardiac massages 15 times while the other person blows into his mouth
twice, and they shall repeat this combination.
(Cardiac massage and mouth-to-mouth respiration)
(3)
Examine his pupils and his pulse sometimes. When the both have returned to normal, stop
the artificial respiration, serve him with a cup of coffee or tea and keep him warm and calm
while watching him carefully. Commit the victim to a medial specialist depending on his
condition. To let him recover from the mental shock, it is necessary for persons concerned to
understand his situations and the necessary treatments.

●Cautions to be used during operation●
●
The customer should refrain from inspecting or repairing the internal parts of
this equipment.
Inspection or repair other than by specialized service personnel may cause
death or a serious injury of any person.
Please contact the sales department of Japan Radio Co., Ltd. or your local
branch, outlet or sales office with respect to maintenance and repair.
When performing maintenance in increment weather, please be sure to shut
the main power off.
Maintenance work performed without shutting the main power off may cause
death or a serious injury of any person by electric shock.
When performing maintenance or inspection of the scanner unit, be sure to
shut off the main power source.
Sudden movement of the scanner may cause death or a serious injury of any
person.
Be sure to shut off the main power source when approaching the scanner unit
for the purposes of maintenance or inspection.
Exposure to electric waves at proximate distances may cause death or a
serious injury of any person.
High Voltage
Since some sections of the modulator (CME-322 or QME-323) generate a high
voltage of about 4000V, no one except service engineers are allowed to touch
inside of the modulator.
The high voltage may cause death or a serious injury of any person by electric
shock.
When the above setting is set to OFF, microwaves are radiated even if the
scanner unit is not rotating, it may cause death or a serious injury of any
person. Therefore, utmost care is necessary.
Make the setting is set ON after the required operation is completed.
III
Make sure that the main power is turned off before maintaining the
equipment.
In particular, when a rectifier is used, a voltage is output from the rectifier
even if the power of the display is turned off and the radar is stopped.
This may cause failures of equipments, or death or a serious injury of any
person by electric shock.
When checking a scanner unit for maintenance, make sure that the main
power is turned off and the safety switch attached to the scanner unit is se to
OFF.
If the power is not turned off, failures of equipments may occur, and death or a
serious injury of any person may occur by electric shock.
And touching a rotating scanner unit may cause failures of equipments, or
death or a serious injury of any person by electric shock.
IV
Do not touch the insides of the scanner unit, transceiver and display unit.
Touching any high voltage area, you will get an electric shock.
For
maintenance, inspection and adjustment of internal parts of these equipment,
consult with our sales office or distributor in your district.
Since the scanner unit radiator rotates, do not approach it.
The scanner unit may start rotating suddenly, and consequently any person
may be struck and be injured. We recommend you to install the scanner unit
radiator on the roof of the wheel house, flying bridge, trestle, radar mast or
any other high position so that no person can approach it. When servicing the
scanner unit, set the scanner unit safety button to the OFF position.
Install the scanner unit at any place higher than any person.
If being exposed directly to electric wave at close range, you may suffer
adverse influence.
When approaching the antenna for maintenance or inspection, set the power
button of the display unit to the ST-BY position.
If being exposed directly to electric wave at close range, you may suffer
adverse influence.
Before starting maintenance work or the like, stop power supply by turning off the
power and disconnecting the power connector from the rectifier and the display.
Even if the power switch is turned off, there are live components in each unit.
In this status, maintenance or inspection work causes an electric shock,
system failure, or accident.
Before disposing of used lithium batteries, insulate by affixing tape to the
positive and negative terminals or by other means.
Otherwise, short-circuiting may occur, resulting in heat generation, bursting
or ignition.
Only specialized personnel shall perform installation work.
Installation work performed by personnel other than specialized personnel
may cause breakdown of the equipment, poor performance, fire, severe elec-tric
shock and other property and human damages.
This adjustment is a function of adjusting tune indication and peak of echo, it
is already made at the factory.
The default value is 64.
The settings must not be changed on the spot.
When the tune indication and peak of echo shift, if the settings are carefully
adjusted, you can not get the tuning.
The gain falles, a collision etc. may occur.
Do not change this adjustment unnecessarily.
An incorrect adjustment may erase the closest target and a collision occurs,
this may cause death or a serious injury of any person.
VI
Use these radar only as assisting devices for navigation.
Also, the officer should make the final decision for maneuvering by himself.
If you make the final decision of maneuvering only on the information which a
radar display, it may become the cause of accidents, such as collision and
stranding.
Do not set the rain/snow clutter function to too high a suppression level.
Otherwise, not only echoes from rain/snow but also the targets of ships or
dangerous objects are suppressed, which may disturb the detection.
Set the best suppression level whenever you use the ran/snow clutter
suppression function.
Do not set the sea clutter suppression function to a level at which it clears all
sea clutters in short range.
Otherwise, not only echoes from waves but also the targets of ships or
dangerous objects are suppressed, which may disturb the detection.
Set the best suppression level whenever you use the sea clutter suppression
function.
The scanner unit shall be installed where there are not large obstacles in the
direction of the ship's heading line in the same plane.
If there is a large impediment in the same plane as the scanner unit, this may
cause the generation of folse echoes. In particular, if such folse echoes appear
at the ship's heading line, monitoring will be difficult and this may cause
inadequate forecasting of danger.
Do not install the scanner unit near chimney's or the exhaust of chimneys.
Soot will cause the performance of the radar to decrease and heat may cause
breakdown.
Do not install direction antenna or VHF antenna in the vicinity of the scanner
unit. Doing so may cause noise in the antenna reception.
Consideration should be given to separating the radar cable from the cables for
the direction antenna and VHF antenna.
These cables should never be bundled into one. Doing so may cause noise in
the antenna reception.
VII
If felt is not provided where the rope contacts the scanner, or if the scanner is
supported near the both ends of the radiator, you may damage the unit.
Be sure to apply the rope to the antenna support.
When mounting the scanner unit, please check the maximum length of the
holding bolts.
If the bolts are too long, it gives severe damage to inside of the scanner.
When mounting the scanner unit, please use the attached bolts.
The mounting base thickness must not exceed 15mm (0.6inch).
Provide a distance of 1m or more between a processing unit and a magnetic
compass.
If a processing unit is installed in a position too close to a magnetic compass, it
may affect the magnetic compass.
Install a processing unit in the location that is not affected by seawater.
The processing unit is not waterproof.
Use correct fuse ratings.
The use of incorrect ratings may cause an equipment failure.
The GPS compass JLR-10 of JRC always can output absolute azimuth without
gyro setting.
Therefore, do not set a gyro value when connecting JLR-10.
Since the modulation section contains a magnetron with stored magnetism, do
not place a lock or a magnetic card close to the modulation section.
Otherwise, failures or data corruption may occur in such devices.
Do not use solvents such as thinner, gasoline, benzene, trichlene, and ketone.
These solvents cause discoloration or deterioration.

Chapter 1 Introduction
1.1 Functions
This device is a marine radar device that utilizes a scanner unit including transmitter and
receiver and 10.4 inch liquid crystal display unit and uses a compact raster scan method for
achieving a fully semiconductor adopted (except for special electron tubes) system.
This equipment comprises radar as defined in the Wireless Telegraphy Act.
1.2 Features
Enhanced fundamental performance of the radar
Through switching among 4 steps in terms of pulse width/cycle switching of frequency and
switching among 3 steps in receiver bandwidth, enhanced fundamental performance of the
radar has been achieved towards display of clearer and high quality images.
Moreover,
through the incorporation of advanced digital signal processing, performance in target
de-tection during increment weather has been improved.
Confirmation of the ship's position and identifying the waypoint at a glance
Through connecting to external navigation equipment such as GPS, the location of the ship
(numerical values) or a mark on the waypoint may be displayed on the screen. This allows for
confirmation of the difference between the waypoint and the ship's heading at a glance.
High operability
A jog dial has been incorporated for simple operation of menu selections, EBL/VRM.
The track ball may also be used to capture the MARPA target in a simple manner.
A system for the direct display of menu items that are frequently used with dedicated keys has
been adopted.

3.1 Operation Flow
Power-on and start
▼
Tuning
▼
Observation and image adjustment
▼
Data acquisition and measuring
▼
Operation termination and stop
This chapter explains operations roughly divided into the following:
Power-on operation
Basic operation
General operation
Function key operation
Power-on operation must be set before this radar is turned on/off or the equipment is operated.
Basic operation is the minimum operation for operating the radar.
General operation is necessary for customizing the settings used with basic operation to best suit
your needs or for using more useful functions.
Function key operation is necessary for storing the settings determined through general
operation by the user or for implementing more advanced usage.

44
3.5.2 When it is raining or snowing [AUTO-RAIN]
Do not set the rain/snow clutter function to too high a suppression level.
Otherwise, not only echoes from rain/snow but also the targets of ships or
dangerous objects are suppressed, which may disturb the detection.
Set the best suppression level whenever you use the ran/snow clutter suppression
function.
When it rains or snows, echoes (rain clutters) from rain or snow are displayed on the PPI screen.
As a result, the images of echoes from ships or the likes are difficult to observe.
Use of the manual or automatic rain/snow clutter function suppresses rain clutters and makes it
easy to observe targets.
While the automatic rain/snow clutter function is working, the manual rain/snow clutter function
(control) cannot be used.
To select the manual or automatic rain/snow clutter function of this radar, operate the
[AUTO-RAIN] control. When the automatic rain/snow clutter suppression function is ON, "A
RAIN" is displayed on the upper right of the screen.
(a) Switching the rain/snow clutter suppression mode
If manual rain/snow clutter suppression is currently selected, pressing the [AUTO-RAIN]
control key changes to automatic rain/snow clutter suppression. If auto rain/snow clutter
suppression is currently selected, pressing the [AUTO-RAIN] control key changes to manual
rain/snow clutter suppression. The automatic rain/snow clutter suppression mode and
manual rain/snow clutter suppression mode are switched back and forth each time the key
is pressed.
(b) Turning the rain/snow clutter control
If manual rain/snow clutter suppression is currently selected, as the rain/snow clutter control
is turned clockwise, the rain/snow clutter suppression function works more strongly.
45
3.5.3 When the sea is rough [AUTO-SEA]
Do not set the sea clutter suppression function to a level at which it clears all sea
clutters in short range.
Otherwise, not only echoes from waves but also the targets of ships or dangerous
objects are suppressed, which may disturb the detection.
Set the best suppression level whenever you use the sea clutter suppression
function.
If the sea becomes rough, echoes (sea clutters) from waves are displayed on the PPI screen. As a
result, the images of echoes from ships or the likes are difficult to view. Sea clutters appear more
clearly in shorter ranges.
Use of the manual or automatic sea clutter function suppresses sea clutters and makes it easy to
observe targets.
While the automatic sea clutter function is working, the manual rain/snow clutter function
(control) cannot be used.
To select the manual or automatic rain/snow clutter function of this radar, operate the
[AUTO-SEA] control. When the automatic sea clutter suppression function is ON, "A SEA" is
displayed on the upper right of the screen.
(a) Switching the sea clutter suppression mode
If manual sea clutter suppression is currently selected, pressing the [AUTO-SEA] control key
changes to automatic sea clutter suppression. If auto sea clutter suppression is currently
selected, pressing the [AUTO-SEA] control key changes to manual sea clutter suppression.
The automatic sea clutter suppression mode and manual sea clutter suppression mode
are switched back and forth each time the key is pressed.
(b) Turning the sea clutter control
If manual sea clutter suppression is currently selected, as the sea clutter control is turned
clockwise, the sea clutter suppression function works more strongly.
46
3.5.4 Using the trackball [TRACK BALL]
[TRACK BALL] enables you to easily measure a distance to a target and the bearing at the same
time.
Operate [TRACK BALL] to position the cursor to the target. The distance to the target and the
bearing are displayed at the right bottom of the screen.
If a navigator such as a GPS is connected, the latitude and longitude at the target position can
also be displayed.
In this case, the target is at a position 4 NM from the own ship.
47
3.5.5 Using VRM [VRM1/VRM2], [JOG DIAL]
VRM is a line for measuring a distance to the target that is displayed on the PPI screen.
Since the size of the circle of VRM can be changed freely through [JOG DIAL], a distance to an
arbitrary target can be measured.
This radar can display 2 VRMs (VRM#1 and VRM#2) concurrently.
To display, select, or erase VRM#1/VRM#2, use the [VRM1/VRM2] key.
The VRM status is as follows:
Neither VRM#1 nor VRM#2 is displayed.
VRM#1 is displayed, and VRM#2 is not displayed.
VRM#2 is displayed, and VRM#1 is not displayed.
Both VRM#1 and VRM#2 are displayed.
Use the following methods to select each state above:
How to operate the [VRM1/VRM2] key
Use the [VRM1/VRM2] key to switch between VRM#1 and VRM#2 and turn ON/OFF
VRM#1/VRM#2.
1. Selecting VRM#1/VRM#2 [VRM1/VRM2]
If neither VRM#1 nor VRM#2 is displayed, VRM#1 or VRM#2 can be selected/displayed by
pressing the [VRM1/VRM2] key.
If both VRM#1 and VRM#2 are displayed, VRM#1 and VRM#2 are selected back and forth by
holding down the [VRM1/VRM2] key.
The currently operable VRM#1/VRM#2 is shown with the VRM value reversed enclosed in
broken lines at the upper right of the screen.
2. Operating VRM#1/VRM#2 [VRM1/VRM2]
The VRM specified in 1 is operable.
After specifying the VRM you want to operate in 1, press [JOG DIAL] several times until the
jog dial mode display at the right bottom of the screen changes to "JOG VRM."
[JOG DIAL] enters the VRM operation mode.
In this status, the VRM can be zoomed in/out.
Turning [JOG DIAL] clockwise "zooms in" the VRM.
Turning [JOG DIAL] counterclockwise "zooms out" the VRM.
3. Erasing VRM#1/VRM#2 [VRM1/VRM2]
If both VRM#1 and VRM#2 are displayed, press the [VRM] key to reverse the value of
VRM#1/VRM#2 you want to retain on the screen. In this status, pressing the [VRM1/VRM2]
key erases the non-reversed VRM.

3.5.7 Changing the bearing presentation method of the PPI screen [AZI MODE]
The following three bearing presentation methods are available for the radar PPI screen:
(a) Relative bearing presentation (Head Up)
Relative bearing is presented with the heading just above (at 0˚ of bearing marker) the PPI
screen.
When the ship's heading changes, the bearing of the echo image on the PPI screen also
changes.
If bearing information cannot be received from a navigator such as a gyrocompass, this relative
bearing presentation is applied.
To place the screen in Head Up mode, press the [AZI MODE] key on the keyboard several times
until the display at the upper left of the screen changes to "HUP."
(b) True bearing presentation (North Up)
True bearing is presented with "North" as due north of the PPI screen.
Even if the ship's heading changes, the bearing of the echo image on the PPI screen does not
change.
(A device such as a gyrocompass is necessary for getting bearing information.)
To place the screen in North Up mode, press the [AZI MODE] key on the keyboard several
times until the display at the upper left of the screen changes to "NUP."
(c) Course Up [AZI MODE]
The ship's heading at time of setting Course Up mode is presented with right above (at 0˚ of
bearing marker) of the PPI screen.
When own ship's course changes after setting as Course Up mode, the bearing of the echo
image on the PPI screen does not change and the ship's heading marker turns by only the
change of the ship's heading.
When the course greatly changes, hold down the [AZI MODE] key to set the course again.
(Course up reset)
54
To place the screen in Course Up mode, press the [AZI MODE] key on the keyboard several
times until the display at the upper left of the screen changes to "CUP."
Caution
● Course up reset is only available in Course Up mode.
Hold down the [AZI MODE] key except course reset mode, the mode is shifted to
gyro setting mode.
Display in North Up mode Display in Head Up mode Display in Course Up mode
● The input of bearing information from the navigator is necessary for changing
the bearing presentation method of the PPI screen.
3.5.8 Changing the center of the PPI screen [OFFCENT]
A display in an arbitrary direction can be lengthened by moving the center (off center) of the PPI
screen.
1. Setting a position to which the center is moved
(a) Move the cursor to the position where you want to move the center of the screen.
(b) Press the [OFFCENT] key. The center of the PPI screen moves to the new position.
2. Canceling the position as the new center
(a) To return the center of the screen to the original, press the [OFFCENT] key again. The
center of the screen returns to the original.
55
Note
Even if the center of the PPI screen is moved, this radar does not erase the images on the PPI screen
including the display of trails and the likes.
You can observe the heading of another ship at any time by freely moving the center of PPI screen.
Caution
● The center of the PPI screen can be moved by up to 90% of the maximum screen
radius. If the center is moved by the allowable maximum into the SHM
direction, the observable range of targets in the heading direction becomes too
small, which is dangerous.
The center of the screen should be moved into the SHM direction for short
observation such as confirmation of another ship's position.
3. Continuously moving the center
To continuously move the center of the PPI screen, operate [TRACK BALL] while pressing the
[OFFCENT] key. When deciding a position as the new center, release the [OFFCENT] key.
Moving of the center stops.
4. Canceling the position as the new center
To return the center of the screen to the original, press the [OFFCENT] key again. The center
of the screen returns to the original.
3.5.9 Using the trail display function [TRAILS]

3.5.13 Highlighting a target by decreasing unnecessary noise (image processing)
[MENU]
Caution
● Do not use this function to view the radar beacon, the START signal, or a target
moving at a high speed on the radar screen.
● This function is used most suitably in TM mode.
When you use the function in RM mode, select N-UP or C-UP. Use of the
function with H-UP may cause images to be blurred.
1. Setting image processing [MENU]
There are three types of image processing, PROC1, PROC2, and PROC3.
PROC1:
Select PROC1 when there is a target moving at a low speed.
The image of a relatively unstable target is highlighted and displayed in stable
state.
PROC1 is effective for suppressing irregular signals like sea clutters.
However, the image of a target moving at a high speed dims.
Use PROC1 in a range of 1.5 nautical miles or less as a rule of thumb.
PROC2:
Select PROC2 to display images in more stable state than "PROC1" does.
PROC2 is effective particularly when there are many sea clutters.
Use PROC2 in a range of 3 nautical miles or more as a rule of thumb.
PROC3:
Select PROC3 when a target is not displayed at the very limit of remote noise.
Use PROC3 in a range of 6 nautical miles or more as a rule of thumb.
Disadvantage of PROC3 is that the target may be more difficult to observe because
noise or the like also appears clearly.
PROC1+3: PROC1 is performed in a preset processing range (the processing range from own
ship), and PROC3 is performed outside the processing range (the processing range
or more).
Use PROC1+3 as navigation when you want to display a target at the very limit of
remote noise while performing PROC1 that makes it easy to observe other ships
influenced by sea clutters in short range.
PROC2+3: PROC2 is performed in a preset processing range (the processing range from own
ship), and PROC3 is performed outside the processing range (the processing range
or more).
Use PROC2+3 as navigation when you want to display a target at the very limit of
remote noise while performing PROC2 that makes it easier to observe other ships
influenced by sea clutters in short range than PROC1 does.
Take the following steps to set image processing:
(a) Press the [MENU] key to display MENU .
(b) Select BASIC and then PROCESS pressing the [JOG DIAL] or [ACQ/ENT] key after
each selection.

Radar trails are displayed in true motion.
CTM: True motion with own ship fixed. This mode displays other targets in relative motion
fixing the own ship to the center.
Radar trails are displayed in relative motion.
"True motion display TM"
The fixed position of own ship on the screen moves according to the ship speed and course. A
fixed target like a land target is fixed onto the screen, and an actually moving target moves on
the screen. The position of own ship is set to a position about 66% of the radius in the opposite
direction of the course on the extension of the ship's heading marker (SHM) when the true
motion display is enabled. The ship starts moving from the position according to the specified
own ship's speed and course.
After that, when the own ship reaches a position 66% of the radius in the opposite direction,
the own ship's position is automatically reset to the position at switching to the true motion
display.

3.6 Use of Function Keys
3.6.1 Overview
The purpose of function keys is to always get the best radar images by :
Storing and using complex radar signal processing settings in the optimum status by usage,
and
Calling optimum signal processing settings for the sea conditions, weather, ship dimensions,
and the like.
Four function key modes are available.
The four modes mean that four different signal processing and radar settings can be stored
separately.
In other words, as long as signal processing setting suitable for short-range observation, optimum
signal processing for trawling, and trail setting have been registered, each setting can be selected
instantaneously by simply pressing the [FUNC] key to switch to the mode.
As explained in the above, you can register any setting for functions 1 to 4. The following are 13
typical signal settings that can be selected:
OFF :
Off
STAND :
Setting for standard situation
COAST :
Setting for coast navigation
DEEPSEA : Setting for deep-sea navigation
FISHNET : Setting for fish net detection
STORM :
Setting for storm weather
CALM :
Setting for calm weather
RAIN :
Setting for rain/snow
BIRD :
Setting for bird detection
LONG :
Setting for long-range detection
BUOY :
Setting for buoy detection
USER1 :
User setting 1 (Used for setting not included in the 11 settings above)
USER2 :
User setting 2 (Used for setting not included in the 11 settings above)
The signal processing settings above are defined in accordance with the titles. Users can make
further detailed settings meeting their needs.
Functions 1 to 4 are factory-set to the titles and signal processing settings as follows:
FUNC1 : COAST
FUNC2 : DEEPSEA
FUNC3 : FISHNET
FUNC4 : RAIN
75
3.6.2 Operation procedures
1. Calling a function
Each time the [FUNC] key is pressed, the cursor moves in the following sequence:
STANDARD → FUNC1 → FUNC2 → FUNC3 → FUNC4 → STANDARD
The title of the currently called mode is displayed at the upper right of the screen.
Suppose that signal processing settings are defined for FUNC1 with COAST as the title,
FUNC2 with DEEPSEA as the title, FUNC3 with FISHNET as the title, and FUNC4 with
RAIN as the title. Each time the [FUNC] key is pressed, the function titles are displayed at
the upper right of the screen in the order of COAST, DEEPSEA, FISHNET, and then RAIN.
You can confirm the currently selected function mode glancing at the screen.
2. Changing the setting of a function key
You can change the settings of a function key just as when performing general operation.
After the title displayed at the upper right of the screen is switched by pressing the [FUNC] key,
settings made in that status are stored as they are.
For example, if FUNC1 (COAST) is selected by pressing the [FUNC] key, the title COAST is
displayed at the upper right of the screen. This explains that the coast navigation function
mode is now active. Settings (e.g., signal processing settings and radar setting) made in the
mode are stored for FUNC1 (coast navigation mode).
3. Changing a function key title
The title displayed at the upper right of the screen can be easily changed.
Perform the procedure below to change any of the factory-set titles previously mentioned.
Take the following steps to change a function key title:
(a) Hold down the [FUNC] key to display the FUNCTION menu.

Chapter 4 How to Interpret the PPI Screen
4.1 Height of and the Distance to the Target
The maximum distance to a target that can be observed with a radar depends not only on the
power of the radar's transmitter, beam width of the scanner unit, and the receiver's sensitivity but
also on height of a target, distance to a target and height of scanner unit line etc. This is because
the radio wave emitted by a radar runs straight, undergoing no influence by the curvature of the
earth surface.
a1=2.23√h1
a2=2.23√h2
a1 + a2=2.23 (√h1 + √h2 )
a1, a2：Unit [Nautical miles]
h1, h2：Unit [Meters]
[Distance and Target]
For example, when the scanner unit lies 3 meters above the sea level, the radar can detect and
display an island with a height of 10 meters at a distance 10 NM away from the scanner unit
position but cannot detect and display an island with a height of 5 meters at the same distance.
This is theoretically true but does not always hold, depending on weather conditions.
For a target located 10 NM away to be displayed on a radar, it theoretically needs to be 7.6
meters or higher. Any targets lower than 7.6 meters cannot be displayed on a radar.
● The target may be unable to be observed when the height of a scanner unit or an
target is low.

4.2 Returns from a Target
The intensity of returns from a target is related not only to the size of the target but also to the
materials and shape of the components making up the target. Accordingly, larger objects do not
necessarily develop strong returns.
On coastlines, in particular, the intensity of returns is dependent on their physiographic features.
For a coastline with a fairly gradual ascent, only inland mountains areas may be displayed as
echoes. This fact needs to be kept in mind when measuring the distance to a coastline.
● Since the echo which returns from a coastline with a fairly gradual ascent is
weak, observation of such land may not be able to be performed.
4.3 Propagation Path of Radio Waves
● Radio waves may be shielded if there is a large intercepting obstacle (e.g.,
mountains, rain, snow, etc.) in their propagation path and any targets behind the
obstacle cannot be observed.

4.3.1 Sea returns
On a wavy sea surface, an echo appears on the PPI screen as a bright defused image at the center
of the screen. This echo is developed by returns from the sea surface. The features of the echo
depend on the size and range of the wave, and the wind direction.
4.3.2 False echoes
There are cases in which nonexistent targets appear as echoes or in which existing targets do not
appear as echoes on the PPI screen. These echoes are called false echoes.
False echoes are produced by the factors explained below.
● Please observe carefully in consideration of there being always false echoes.
(a) Ghost
Depending on the location where the scanner unit is installed, radio waves are emitted from
nearby chimney stacks or masts, developing ghosts. Consequently, targets that are located
in those direction may not appear as echoes on the PPI screen.
The presence of these ghosts can be identified by observing sea returns and checking the
returns for dim areas or voids.
If a ghost is detected, remember the direction in which it appears and observe the target
carefully.
(b) Side echo
There are cases in which an arc-shaped broken line appears over the same
range as the echo from the target. This image is caused by the side lobes
of the beam emitted from the scanner unit. This type of false echoes can
easily be identified if the target stands alone.
(c) Indirect echo
The direction of the radio wave
from the radar may be changed by
a reflection (secondary reflection)
at a chimney stack or mast of a
ship, developing a false echo in a
direction in which there should be
no target.
The indirect echo developed by the
secondary reflection appears in the
direction of the chimney stack or
mast that reflected the radio wave.
87
(d) Multiple echo
Multiple echoes are developed by multiple reflections caused by a building or large vessels
that has large vertical surfaces. These echoes are spaced at an equal interval, with the one
that is closest to the own ship being the true echo.
(e) Radar interference
If there is a radar that uses the same frequency as that of the own ship near the own ship,
interferences caused by that radar appear on the PPI screen. These interferences appear as
clusters of spots of varying patterns. Since they do not occur at the same location with time,
they can easily be distinguished from true echoes.
Radar interferences can be reduced or eliminated by choosing "ON" from "FUNCTION"-"IR".
[Examples of radar interferences]

4.4 Display of Radar Transponder
SART (Search and Rescue Radar Transponder) is life preserving device approved by GMDSS
which is used for locating survivors in the event of a disaster or distress. SART operates in the
9GHz frequency band. When it receives a radar signal (interrogating radio wave) of 9GHz
transmitted by a rescue ship or aircraft radar, SART transmits a series of respouse signals to the
searchers to indicate the distress position.
In order to see the SART or radar beacon mark on the radar screen.

[Example]
Caution
● When above settings ① to ⑥ are made to display SART signals, objects
around the own ship will not appear on the radar screen, so perform thorough
visual monitoring of the sea area around the own ship to avoid any collision or
stranding.
Further, when more than one radar systems are mounted, while using a 9GHz
band radar for searching SART signals, be sure to use another radar as an
ordinary radar to perform monitoring of objects around the own ship to avoid
any collision, check of the position of the own ship to avoid any stranding, and
so on.
Need to return the set for normal operation on completion.

Chapter 5 Maintenance and Inspection
5.1 General Maintenance
The customer should refrain from inspecting or repairing the internal parts of this
equipment.
Inspection or repair other than by specialized service personnel may cause death
or a serious injury of any person.
Please contact the sales department of Japan Radio Co., Ltd. or your local branch,
outlet or sales office with respect to maintenance and repair.
When performing maintenance in increment weather, please be sure to shut the
main power off.
Maintenance work performed without shutting the main power off may cause death
or a serious injury of any person by electric shock.
Caution
● When cleaning the surface, please refrain from using organic solvents such as
thinner or benzene.
Use of such organic solvents may damage the surface coating.
When cleaning the surface, remove dust and grime and wipe with a clean dry
cloth.
The following maintenance steps are required to ensure that the radar always operates in the
optimal condition.
Since breakdowns will be reduced through maintenance, periodic
maintenance is recommended.
General maintenance steps common to all equipment are as follows.
Cleaning
Remove dust, grime and sea water that has adhered to the unit. Use dry cloth to clean the
unit. In particular, use a brush to clean the ventilating opening to ensure smooth flow of air.
90
5.2 Scanner Unit
When performing maintenance or inspection of the scanner unit, be sure to shut off
the main power source.
Sudden movement of the scanner may cause death or a serious injury of any
person.
Be sure to shut off the main power source when approaching the scanner unit for
the purposes of maintenance or inspection.
Exposure to electric waves at proximate distances may cause death or a serious
injury of any person.
(1) Radiation unit
If the front of the radiation unit is soiled with soot, salt, paint specks, bird excrement or other
alien matter, electric waves may become attenuated and reflection may occur thus causing
degradation in the performance of the radar.
The radiation unit should be inspected and always kept clean by wiping with cloth soaked in
alcohol or water in the event of soiling.
Solvents such as gasoline, benzene, trichlene or ketone should never be used for this purpose.
(2) Pedestal
The pedestal and attachment bolts of the scanner unit should be inspected periodically for
erosion and maintained to ensure safety.
Painting is the best measure for preventing
erosion and it is recommended that this be undertaken once in half a year.
5.3 Display Unit
Cleaning the LCD
When dust adheres to the LCD, transparency degrades and the images become dark.
Cleaning is performed using cloth soaked in water (flannel or cotton). Wiping vigorously
with dry cloth or the use of gasoline or thinner should be avoided.
Caution
● Vigorous wiping with dry cloth or the use of gasoline or thinner should be
avoided in cleaning the LCD.
Such action may cause scratches and deterioration.

5.6 Actions to Deal with Abnormalities and Breakdown
In the case of semiconductor circuits, except in cases of problems in the design or inspection of
such circuits or causes that are external or caused by humans, breakdown or deterioration of the
circuit does not often occur. In general, the causes of breakdown that are relatively frequently
found are wire cut in the high resistance device due to high humidity, defect in the variable
resistance and defect in the contact of switches and relays.
Moreover, in many cases the cause for breakdown is not a defect in parts but rather poor
adjustment (particularly inadequate tuning adjustment) or poor maintenance (particularly defect
in cable contact) and inspecting or readjusting these aspects is often effective in the case of
perceived abnormality or breakdown. The following table should be taken into consideration in
the case of abnormalities or breakdown.
There is always a cause for a blown fuse and after replacing the fuse, it is necessary to investigate
the related circuits even when no abnormality remains. However, consideration should be given to
the fact that there is significant variance in the characteristics of fuses.

Chapter 9 Installation
This chapter has been written for the service technicians to read in case of installation.
Only specialized personnel shall perform installation work.
Installation work performed by personnel other than specialized personnel may
cause breakdown of the equipment, poor performance, fire, severe elec-tric shock
and other property and human damages.
9.1 General
Proper installation of a radar unit is essential for extracting full capability of the unit reliably and
for facilitating troubleshooting and maintenance.
Follow the guidelines given below when
installing the radar unit.
(a) Install the scanner unit as high as possible while taking its weight into consideration.
(b) Install the display unit in the wheel house for comfortable observation.
(c) The scanner unit and display unit are connected by 20m compound cable with an internal
shield. The maximum permissible cable length is 30 m (only when DC 24V or DC 32V is
input). Cables longer than 30m will deteriorate the radar performance of the radar unit.
108
9.2 Installing the Scanner Unit
9.2.1 Selecting the installation location
The scanner unit shall be installed where there are not large obstacles in the
direction of the ship's heading line in the same plane.
If there is a large impediment in the same plane as the scanner unit, this may
cause the generation of folse echoes. In particular, if such folse echoes appear at
the ship's heading line, monitoring will be difficult and this may cause inadequate
forecasting of danger.
Do not install the scanner unit near chimney's or the exhaust of chimneys.
Soot will cause the performance of the radar to decrease and heat may cause
breakdown.
Do not install direction antenna or VHF antenna in the vicinity of the scanner unit.
Doing so may cause noise in the antenna reception.
Consideration should be given to separating the radar cable from the cables for the
direction antenna and VHF antenna.
These cables should never be bundled into one. Doing so may cause noise in the
antenna reception.
109
Take the following into consideration when selecting the installation location:
(1) Consider the weight of the scanner unit and decide what height it can be raised for
installation in the ship.
(2) Height at which the scanner unit is installed has to do with the maximum detectable range,
the higher its position is the better. On the other hand, however, if raised too high, at a point
beyond the beam width (-3 dB position) along the vertical direction radio wave energy will be
affected noticeably, making it difficult to spot targets lying very near.
When installing the unit, consider its weight, longest permissible cable length, and the
requirements during future maintenance.
Refer to 4.1, "Height of and the Distance to the Target" for the relation between the height of
the scanner unit and maximum detectable range.
(3) If the width of the radiated beam is 2θ (most energy is concentrated within this width), then
the energy reduces considerably in directions outside the 2θ range. Thus, if the scanner unit
is raised too high it will be difficult to spot targets lying very close-by. If, on the other hand,
the scanner unit is installed low, it will be obvious to miss distance targets, and the ship's
mast derrick, funnel, etc. will intercept the radiated beams, making most of your targets
unobservable. In general, the lowest position of the scanner unit should be as shown by the
line AB in the following figure. For example, angle 2θ is 20˚ for the radar of JMA-5110.
Normally, when deciding the height of the scanner, it is necessary to make sure that the
ship's mast does not obstruct the beams.
=12.5°
: Vertical beam width
Lowest Position of Scanner Unit
(4) When selecting the position of the scanner along the length of the ship, make sure that the
shading caused by the ship's mast on the radio waves does not coincide with the ship's center
line. If the ship has no large obstruction towards front, normally the scanner is placed on
top of the steering room along the ship's center line.
(5) Avoid placing DF (direction finder) of VHF (communications) antenna near the scanner as
these will interfere with the radiated waves.
(6) Soiling of the radiating surface of the scanner by the smoke from funnel affects radar
performance, clean the radiating surface form time to time. To facilitate maintenance, place
the scanner in the right position and use mast and tower of the right structure.
(7) Note that, if placed near ship's flag or rope may cause by wind to wrap or coil around the
radiator and damage it.
(8) Do not select the derrick post as the location for scanner installation. The derrick post is
subject to large vibrations.
110
(9) Note the swing circle of the scanner and allow a distance of at least (swing circle/2)+200 mm
between scanner swing center and other installations (say, mast or radio antenna).
Scanner swing circle in the radar of JMA-5106/5110 is shown in the following table.

9.2.2 Installation procedure
(a) If it is found that there is no height above the roof of the wheel house enough to directly
accommodate a scanner unit, install a pedestal or radar mast.
(b) In addition to a pedestal or radar mast, it is necessary to provide an appropriate staging for
convenience in installation, maintenance, adjustment, and repair of the scanner unit.
1. Stand
Install the stand as instructed in drawing Fig.1.1, 1.2 and 1.3 in Chapter 1. Direct the cable
gland towards ship's stern, making sure that scanner installation base is parallel to surface of
the sea. If the stand is installed directly on the top of steering room and find that the scanner
is not sufficiently high, use a pedestal or radar mast. Normally, if height of the scanner is not
more than 2 m above the roof of the steering room, place the scanner on a pedestal fixed with
angle joints. If, on the other hand, the scanner is positioned below a height of 2 m, use a
cylindrical radar mast, and place the scanner on top of it. Whether a pedestal of radar mast is
used it is necessary to provide proper foothold to facilitate the installation, maintenance,
adjustment, and repairs. (Refer to the following figure)
Height

2. Suspending the Scanner
The scanner is supplied assembled, with felt wound around the area where the suspension
rope will contact it. Engage the sling with the scanner as shown in the following figure.
Scanner Suspention
If felt is not provided where the rope contacts the scanner, or if the scanner is
supported near the both ends of the radiator, you may damage the unit.
Be sure to apply the rope to the antenna support.
3. Paint
Apply necessarily paint on the fixing legs, bolts, nuts, etc. to prevent corrosion.
4. Magnetism
Place the scanner at least 3m away from the nautical instruments such as the compass or the
chronometer to protect these from the effect of the magnetron inside the scanner.

Caution
● Incorrect connection between the ship's power supply or the rectifier and the
power cable may cause an equipment failure.
Selecting a cable when a long power cable is required
● The input voltage to an indicator is determined by subtracting the voltage drop up
to the power cable from the ship's power supply voltage.
Therefore, if the power cable is too thin or too long, the voltage drops substantially,
preventing the radar from functioning at its full capacity.
Use the following
guideline for selecting a power cable.
(a) Take the voltage fluctuation rate into consideration when determining a
voltage (Vs) value of the ship's power supply.
(b) Use the following formula for calculating a voltage drop (V).
V=2LRKI

9.3.14 Connecting external buzzers
This equipment is equipped with dry contact output for external buzzers.
Dry contact is output from a jumper set between pins 6 and 7 from the 8-pin connector of J5. The
contact of the output is a capacity up to 1A/30V.
If a greater current/voltage is applied, install equipment of adequate contact capacity such as
relay in the external section.
If the current/voltage exceeds the contact capacity, the contact of this equipment becomes fused
and the external buzzer keeps ringing, causing an extremely dangerous situation.

9.4 Changing Ship's Power
Use correct fuse ratings.
The use of incorrect ratings may cause an equipment failure.
● Modify the ratings as follows according to the ship's power.
(At product delivery, a fuse of 24V is provided.)
1. Display
Three types of fuses, F1, F2, and F3, are available.
F1
: Fuse for the processing unit (10A)
F2
: Fuse for scanner unit transmitter-receiver (or less)
F3
: Fuse for scanner unit motor (or less)
A fuse for a processing unit (F1) is 10A regardless of the input voltage and scanner unit output.
A fuse for a modulator (F2) and a fuse for a scanner unit motor (F3) change according to the
input voltage as shown in the table below.
When the product is purchased, the 6.3A timelag fuse is inserted in the F2 fuse as the fuse for
12V, and the 5A timelag fuse is inserted in the F3 fuse as the fuse for 12V.
Surely exchange for the fuses suitable for the scanner unit and ship's power by using the table
below.
For NKE-2042 (4kw radome type scanner unit), fuse insertion is not necessary since F3 (fuse
for motor) is not available.

9.10 Maintenance
9.10.1 General maintenance
To operate radar equipment constantly in a good condition, the following maintenance is necessary.
Maintain the equipment periodically. Periodic maintenance reduces failures.
The following common maintenance points are applied to each unit.
1. Cleaning the equipment
Remove dust, stains, and seawater from the cabinet as much as possible. Use a dry cloth for
cleaning.
2. Checking the tightening of screws
Check the tightening of screws of assembly and component setting crews that are used for the
equipment.
3. Checking connections
Check the cable connections between equipment units (scanner unit - processing unit,
processing unit - power, processing unit - keyboard unit, processing unit - display unit,
processing unit - optional equipment) if the equipment units are electrically connected.
Make sure that the main power is turned off before maintaining the equipment.
In particular, when a rectifier is used, a voltage is output from the rectifier even if the
power of the display is turned off and the radar is stopped.
This may cause failures of equipments, or death or a serious injury of any person
by electric shock.
184
9.10.2 Scanner unit
When checking a scanner unit for maintenance, make sure that the main power is
turned off and the safety switch attached to the scanner unit is se to OFF.
If the power is not turned off, failures of equipments may occur, and death or a
serious injury of any person may occur by electric shock.
And touching a rotating scanner unit may cause failures of equipments, or death or
a serious injury of any person by electric shock.
Since the modulation section contains a magnetron with stored magnetism, do not
place a lock or a magnetic card close to the modulation section. Otherwise,
failures or data corruption may occur in such devices.
1. Radiation section
(a) Radiation side of the radiation section (JMA-5104: All sides of the radome cover)
If JMA5106/JMA-5110 (entire area of the radiation section) is contaminated or damaged
by smoke, dust, or paint, attenuation and reflection of waves occur, causing deterioration
of radar performance. Check the radiation area occasionally and keep it clean by wiping
with a soft cloth dipped with alcohol or moisturized cloth if it is dirty.
Do not use solvents such as thinner, gasoline, benzene, trichlene, and ketone.
These solvents cause discoloration or deterioration.
185
2. Rotation driving section
(a) Greasing gears
Apply grease on the faces of the teeth of each gear using a spatula or brush. The more
frequently greasing is applied, the longer the life span becomes, preventing the abrasion.
Greasing is necessary at least once in six months.
Use "Mobilux 2" of Mobile Oil or equipment product for the grease.
(b) Driving motor
i) Attenuator
Greasing is not necessary unless there is oil leakage.
ii) Motor
The life span of the brush itself is 2000 hours. When the brush is worn out to a half of
the entire length, replace it.
The communicator must be kept clean all the time. If carbon dust is stuck and cannot
be removed with a dry cloth, polish the section with sand paper of No.150 to 400.
The carbon brush can be removed by removing the caps on both sides of the bottom of
the motor.
