key after each selection.
(c) The menu below is displayed. Select | OFF | or and then press the
[JOG DIAL] or [ACQ/ENT] key to determine the selection. Note The interference elimination levels are > > starting with the lowest level. However, if the set level is too high, a problem such as the decrease of sensitivity occurs. The lowest level should be selected for general use. 44 3.5.2 When it is raining or snowing [AUTO-RAIN]
A\CAUTION 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.

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 [AZ] 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 [AZ] MODE] key on the keyboard several times until the display at the upper left of the screen changes to "NUP."
(c) Course Up [AZ] 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.

[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 PROCS. 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 hike 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. PROCS: Select PROC3 when a target is not displayed at the very limit of remote noise. Use PROCS in a range of 6 nautical miles or more as a rule of thumb. Disadvantage of PROCS 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 PROCS 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 chutters in short range. PROC2+3: PROC2 is performed in a preset processing range (the processing range from own ship), and PROCS 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.

[MENU]. 74 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 (.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.

By adding the optional keyboard (NCE-7640), either of the two keyboards can be used independently to control one antenna. When one keyboard is being used, it will not be possible to use the other keyboard, with the exception of a few functions (eg., the keyboard switching operation and changing from transmission to standby). Take the following steps to switch between keyboard 1 and keyboard 2.
(a) Hold down the [GAIN/PL] key to display the following menu. PANEL CONTROL SELECTION RR a4
(b) Turn the [JOG DIAL] to select | PANEL 1 | or | PANEL 2 |, then press the [JOG DIAL] or
[ACQ/ENT] key.
(c) The menu below is displayed. Select and then press the [JOG DIAL] or [ACQ/ENT]
key. Be COST
(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 retum 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. 85 A\WARNING Immediately after switching the keyboards, the modes of the [GAIN/PL], oO {[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. 86 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. Earth a=2.237 hi ax=2.23 he ai + as=2.23 hi + v he) ai, a2 : Unit [Nautical miles]
hi, he : 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. Island not displayed on the screen h;(meters) 1+ae(NM) hz (meters) Scanner unit height Distance Target height 87 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. Mountains that are displayed on the screen We Shoreline that are not displayed on the screen ____ 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 A ship that is not displayed because of an because of heavy rain in between island in between the own ship and the the own ship and the island target ship 88 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.
(ec) Indirect echo The direction of the radio wave from the radar may be changed by True echo 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 False echo produced by secondary reflection appears in the ( Radio wave changes its direction as it secondary reflection is reflected at a chimney stack, direction of the chimney stack or developing a false echo, 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. False echoes NT Gita. t The echo closest to the own ship is the real 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".

90 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.

/A\DANGER 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. 92 5.2 Scanner Unit 4\ DANGER 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.
(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. 93 5.4 Special Parts JMA-5104 REE [Nave [ie [water [Lost se] JRC Cale JMA-5106 JMA-5110 Diode limiter Scanner unit | 5EZAA00024

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. No. | Condition of the Breakdown Conceivable Cause

A\WARNING 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 A\CAUTION 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. 111 Take the following into consideration when selecting the installation location:

(6)
(7)
(8) Consider the weight of the scanner unit and decide what height it can be raised for installation in the ship. 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. If the width of the radiated beam is 20 (most energy is concentrated within this width), then the energy reduces considerably in directions outside the 26 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 20 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. on 2 @: Vertical beam width Lowest Position of Scanner Unit 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. Avoid placing DF (direction finder) of VHF (communications) antenna near the scanner as these will interfere with the radiated waves. 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. Note that, if placed near ship's flag or rope may cause by wind to wrap or coil around the radiator and damage it. Do not select the derrick post as the location for scanner installation. The derrick post is subject to large vibrations. 112

Scanner swing circle in the radar of JMA-5106/5110 is shown in the following table. Swing circle (mm) Swing circle/2+200 (mm) NKE-2062 1220 810 NKE-2102 | 6 | 1910 1155 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 1.8 in Chapter 1. Direct the cable gland towards ship's stern, making sure that scanner installation base is parallel to surface of the sea. Ifthe 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, maimtenance, adjustment, and repairs.
