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 to his face. 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

②

③

(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) 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) 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 2 times, 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.

If maintenance work is performed without shutting the main power off, there is a risk of dying or getting 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.

If the scanner suddenly rotates and it hits the human body violently, there is a risk of dying or getting 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.

If exposured to electric waves at proximate distances, there is a risk of dying or getting 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.

There is a risk of dying or getting 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.

If maintenance work is performed without turning off the main power, there is a risk of equipments breaking down, and dying or getting 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, there is a risk of equipments breaking down, and dying or getting a serious injury of any person may occur by electric shock.

And if the rotating scanner unit is touched, there is a risk of equipments breaking down, and dying or getting a serious injury of any person by electric shock.

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.

Immediately after switching the keyboards, the modes of the [GAIN/PL],

[AUTO-TUNE] , [AUTO-SEA] and [AUTO-RAIN] knobs may be different from what they were before switching. Sensitivity might also be lowered, and this could cause a collision.

Each time the active keyboard is switched, be sure to readjust the four knobs above so that they are at their optimum settings.

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.

When you directly connect with the ship's power supply without using the optional rectifier, measure the voltage between the hull's earth and the positive side of ship's power spply, and the hull's earth and the negative side of this. And check voltage of 50 volts or more is not required.

If voltage of 50 volts or more is required, take the measures which do not require 50 volts or more between the above mentioned terminals.

Connection without taking the measures causes system failure or accident.

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 may occur.

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.

▼

Operation termination and stop

This chapter explains operations roughly divided into the following:

- 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.

The following explains each basic operation:

3.2 Power-on Operation

1. Turning on the power [STBY]

To turn on the power, press the [STBY] key.

When the power is turned on, the countdown timer is displayed on the screen, and the standby state is placed after 1 minute and 30 seconds.

The total duty time and total transmitting time are displayed. Refer to the time display when carrying out maintenance work. The time display includes a slight error.

2. Transmitting [TX/PRF]

To transmit data from the standby state, press the [TX/PRF] key.

To change the transmitting state back to the standby state, press the [STBY] key.

This radar can be tuned manually or automatically. To switch between manual tuning and automatic tuning, press the [AUTO-TUNE] control key. When automatic tuning is selected, "A" is displayed to the left of the tuning indicator at the right bottom of the screen.

1. Switching the tuning mode

If manual tuning is currently selected, pressing the [AUTO-TUNE] control key changes to automatic tuning. If automatic tuning is currently selected, pressing the key changes to manual turning. The automatic tuning mode and manual tuning mode are switched back and forth each time the key is pressed.

2. Turning the tuning control [AUTO-TUNE]

If manual tuning is currently selected, enlarge the image by turning the tuning control on the keyboard. The tuning indicator serves as a rule of thumb for manual tuning. Adjust the image so that the pointer of the indicator reads the maximum value.

Automatic tuning does not need the turning of the tuning control.

If no image appears, turn the sensitivity control on the keyboard fully to the right, and turn the sea clutter control and the rain/snow clutter control fully to the left.

3.2.3 Observation and image adjustment [+RANGE-]

Display the optimum image by turning the tuning control (if manual tuning is selected), sensitivity control, sea clutter control, and rain/snow clutter control on the keyboard.

The image observation range can be changed by pressing the [+RANGE-] key.

The currently selected range is displayed at the upper left of the screen. (See 2.2, "Description of

Screen Display.")

3.2.4 Data acquisition and measuring

For each operation, see 3.4, "Basic Operation" and Chapter 4, "Interpret the PPI Screen."

3.2.5 Operation termination and stop [STBY], [TX/PRF]

1. Canceling transmission [STBY]

Press the [STBY] key.

Transmission is canceled and the screen enters the standby state.

2. Turning off the power

Press the [STBY] key and [TX/PRF] key at the same time.

The radar enters the stopped state and all the functions stop.

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.

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)

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.

● 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. the 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.

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: the key to display MENU .

(b) Select BASIC and then PROCESS pressing the [JOG DIAL] or [ACQ/ENT] key after each selection.

1. Switching the motion mode

(a) Press the [TM/RM] key. The screen display and function changes in the following sequence:

RM: Relative motion. This mode displays other targets in relative motion fixing the own ship to the center.

Radar trails are displayed in relative motion.

TM: True motion. This mode displays the own ship and other targets in true motion on the screen with the earth being fixed.

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 :

RAIN :

BIRD :

LONG :

Setting for calm weather

Setting for rain/snow

Setting for bird detection

Setting for long-range detection

BUOY :

USER1 :

USER2 :

Setting for buoy detection

User setting 1 (Used for setting not included in the 11 settings above)

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

1. Calling a function

STANDARD → FUNC1 → FUN C2 → 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.

(a) Hold down the [FUNC] key to display the FUNCTION menu.

(b) The menu below is displayed. Select the function key FUNC1 to FUNC4 of which title you want to change, and then press the [JOG DIAL] or [ACQ/ENT] key.

3.7.8 Replacing the battery (BT1)

The battery (BT1) needs to be replaced regularly to hold the set information.

(a) Replacing the battery (BT1)

The battery is provided in the main control circuit (CMC-1190).

The battery model is CR2477-1VC.

Ask the nearest sales agent to replace the battery.

(b) Initial settings after battery replacement

- Even if the power is turned off, the settings of menus and software keys are held through this lithium battery. Consequently, when the power is turned on next, the radar is operable in the status in which it was most recently used.

- When the battery reaches the end of its useful life, all the settings including menus are automatically reset.

Therefore, the initial settings need to be made again after battery replacement.

Caution

● When the battery nears the end of its useful life, the range and bearing may not be measured correctly.

Replace the battery immediately, and make the initial settings.

(c) If the battery cannot be replaced immediately, as first-aid measures, make the initial settings each time you turn on the power. In this case, note that all the settings are reset when the power is turned off.

● For the initial settings, see 9.7, "Initialization."

3.7.9 Procedure if an incomprehensible symptom occurs during use of the radar

If a symptom such as the distortion of screen display or the refusal of switch operation takes place during use of the radar, perform the initialization procedure below.

PANEL CONTROL SELECTION

PANEL SELECTED

ARE YOU SURE?

YES

(d) When a keyboard other than the one being used is selected from this status, only the

[GAIN/PL] key and [STBY] key will work. The other keys will not function. In order to be able to use the current keyboard, repeat the above process from (a), then select a keyboard other than the one selected in step (b) to set the current keyboard for operation.

Note

Even if the keyboard currently being used does not have the operating rights, the [STBY] key on the keyboard will still be effective as explained above.

This is to allow either keyboard to immediately switch the system from transmission to standby when there is an emergency.

Therefore, a keyboard that does not have operation rights can switch the system to standby, but it cannot change it back to the transmission mode. In order to return the system to the transmission mode, either the keyboard with the operating rights should be used, or the above procedure from (a) should be followed to acquire the operating rights, then switch the system to the transmission mode.

Immediately after switching the keyboards, the modes of the [GAIN/PL],

[AUTO-TUNE], [AUTO-SEA] and [AUTO-RAIN] knobs may be different from what they were before switching. Sensitivity might also be lowered, and this could cause a collision.

Each time the active keyboard is switched, be sure to readjust the four knobs above so that they are at their optimum settings.

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. a

, a

, h

)

： Unit [Nautical miles]

： 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.

An island that is not displayed because of heavy rain in between the own ship and the island

A ship that is not displayed because of an island in between the own ship and the target ship

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.

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.

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.

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.

(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.

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.

① RANGE SCALE : Select 6 or 12 nm

② SEA CLUTTER control : Set to minimum

③ AUTO SEA : OFF

④ TUNE control

⑤ IR

⑥ PROCESS

: DETUNED to reduce the clutter

: Set IR OFF

: Set PROCESS OFF

[Example]

Caution

● When above settings ① 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.

If maintenance work is performed without shutting the main power off, there is a risk of dying or getting 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.

5.2 Scanner Unit

When performing maintenance or inspection of the scanner unit, be sure to shut off the main power source.

If the scanner suddenly rotates and it hits the human body violently, there is a risk of dying or getting 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.

If exposured to electric waves at proximate distances, there is a risk of dying or getting a serious injury of any person.

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.

110

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.

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.

111

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°

2 : 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.

112

(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.

(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)

113

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.

114

9.2.3 Connection of cables to be assembled

1. Radome scanner unit (NKE-2042)

115

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).

3. Crimp the shielding cable.

4. Install the red cables on the + side of the ship's power supply, the black cables on the - side of the ship's power supply, and the shielding cable in the hull's earth.

If voltage of 50 volts or more is required, take the measures which do not require

50 volts or more between the above mentioned terminals.

Connection without taking the measures causes system failure or accident.

Inset cable CFQ-6911-5 into processing unit J1.

Caution power cable may cause an equipment failure.

127

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

L : Cable length

R : Direct current resistance at 20˚C (Ω/m)

K : Conductor resistance temperature counting (=1.22)

I : Maximum peak current (A)

To input NMEA data such as position information from the GPS equipment of JRC or a different manufacturer by acquiring azimuth data from JLR-10, connect a cable from GPS equipment using the connection method that is described in 9.3.9, "Connecting a GPS receiver and NMEA equipment" or using a reserved cable, P3. Do not use the cable from JLR-10, which is inserted in GPS(J3) input, as shown in Photograph 3.

2. When not using a dedicated cable

To connect azimuth information data from a GPS compass, use J5 8-pin connector P5

(LTWD09BFFA-L180) that is included in the main unit package.

See below for the connection method.

9.3.11 Connecting an electromagnetic compass

Caution and power cable.

If neither connection nor voltage is right, it may cause an equipment failure.

Azimuth information can be input to a radar indicator unit if the electromagnetic compass is equipped with a NMEA0183 output pin. (An electromagnetic compass without NMEA0183 output pin cannot be connected.)

To connect azimuth information data from an electromagnetic compass, use 8-pin connector P5 for

J5 (LTWD09BFFA-L180).

For the connection, connect NEMA0183+ from the electromagnetic compass to pin 3 and

NEMA0183- from the electromagnetic compass to pin 4.

The data that can be input from a magnetic compass is NMEA-0183 (HDT/HDM/HDG format).

Caution optional MARPA is connected.

The data input from GPS compass or gyro is required.

136

By purchasing an optional item, NSK Unit NCT-4106, gyro and electromagnetic log can be connected.

For connecting, use the CFQ-6998 dedicated cable of JRC that is enclosed by the NCT-4106 or the

CFQ-6934 optional cable.

NCT-4106 can be connected easily with the processing unit by using this cable.

And the NCT-4106 is built in the interface circuit for high capacity external buzzer contact output

The use of incorrect ratings may cause an equipment failure.

(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

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.

If maintenance work is performed without turning off the main power, there is a risk of equipments breaking down, and dying or getting a serious injury of any person by electric shock.

195

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, there is a risk of equipments breaking down, and dying or getting a serious injury of any person may occur by electric shock.

And if the rotating scanner unit is touched, there is a risk of equipments breaking down, and dying or getting 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.

196

2. Rotation driving section

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. 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.
