Page 7: Preface
PREFACE Thank you very much for purchasing the JRC marine radar equipment, JMA-5200MK2 series. This equipment is a marine radar equipment designed to obtain safe operation of marine ships. This equipment consists of a radar signal transmitter-receiver unit, a LCD display unit and a scanner unit as its main units.
Page 8: Before Operation
Before Operation Pictorial Indication Various pictorial indications are included in this manual and are shown on these equipment so that you can operate them safety and correctly and prevent any danger to you and/or to other persons and any damage to your property during operation.
Page 9: Precautions
PRECAUTIONS DANGER Never conduct inspection or repair work of equipment components. Inspection or repair work by uncertified personnel may result in fire hazard or electrocution. For inspection and repair work of equipment components, consult with our branch office, branch shop, sales office, or our distributor in your district. When conducting maintenance, make sure to turn the main power off.
Page 10 WARNING Never directly touch the internal components of the antenna, receiver/transceiver, or indicator. Direct contact with these high-voltage components may cause electrocution. For maintenance, inspection, or adjustment of equipment components, consult with our branch office, branch shop, sales office, or our distributor in your district.
Page 11 WARNING Do not change MBS Level/Area unless absolutely necessary. Incorrect adjustment will result in deletion of nearby target images and thus collisions may occur resulting in death or serious injuries. When cleaning the display screen, do not wipe it too strongly with a dry cloth.
Page 12 CAUTION A malfunction may occur if the power in the ship is instantaneously interrupted during operation of the radar. In this case, the power should be turned on again. Always use the automatic tuning mode. Use the manual tuning mode only when the automatic tuning mode does not provide the best tuning state due to deterioration of magnetron for example.
Page 13 CAUTION When using the [AUTO RAIN] function, never set the suppression level too high canceling out all image noises from the rain or snow at close range. Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited.
Page 14 CAUTION Use the target tracking function (TT) only as a navigation aid. The final navigation decision must always be made by the operator him/herself. Making the final navigation decision based only on the target tracking function (TT) information may cause accidents. The target tracking function (TT) information such as vector, target numerical data, and alarms may contain some errors.
Page 15 CAUTION When a small value is set as a hysteresis condition, a tracked target near an AIS target is identified as the AIS target and may thus disappear from the display. For example, when a pilot vessel equipped with the AIS function (a small target which is not a tracked target) goes near a cargo vessel which is a tracked target without the AIS function, the tracked target symbol for...
Page 16 CAUTION Do not change the quantization level settings unless absolutely necessary. If set at an inappropriate value, the acquisition or tracking function of the target tracking function (TT) deteriorates, and this may lead to accidents. Any adjustments must be made by specialized service personnel.
Page 17 CAUTION Never changes or modifications the equipment by user with not expressly approved method. Otherwise, the party responsible for compliance could void the user’s authority to operate the equipment. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules.

Resolution between adjacent targets and swapping during automatic target tracking Depending on the particular distance and echo size, resolution between adjacent targets during automatic target tracking usually ranges somewhere between 0.03 to 0.05 NM.
Page 251: Preparation
5.1 PREPARATION PREPARATION This section explains the features of the target tracking and AIS functions, and the initial setting for using each function. Before the target tracking function or AIS function can be used, the corresponding optional device must be installed.
Page 252: Collision Avoidance
5.1.1 Collision Avoidance Problems of Collision Avoidance in Navigation Marine collision avoidance is one of the problems that have been recognized from of old. Now, it will be described briefly who the collision avoidance is positioned among the navigational aid problems. The navigation pattern of all mobile craft constitutes a system with some closed loops regardless of the media through which the mobile craft travels, whether air, water, the boundary between air and water, or space.
Page 253 5.1 PREPARATION Basic Concept of Collision Avoidance There are two aspects in collision avoidance: collision prediction and avoidance. Collision prediction is to predict that two or more vessels will happen to occupy the same point at the same time, while collision avoidance is to maneuver vessels not to occupy the same point at the same time.
Page 254 Relative Vector and True Vector From two points of view, collision prediction and avoidance, it is necessary to obtain the relative vector of other ship for prediction and the true vector of other ship for collision avoidance in order to grasp other ship’s aspect. The relationship between the relative vector and true vector is shown in Fig.

Page 256 Types and Definitions of AIS Target Symbols Vector/Symbol Definition Remarks This symbol is displayed when received data is valid. Sleeping target The direction of the triangle’s vertex indicates the target’s bow or course. The heading direction is displayed with a solid line, and the course vector is displayed with a dotted line.
Page 257 5.1 PREPARATION The vector of an AIS target is to be displayed with a vector over ground or over water, depending on the speed sensor setting and current offset setting. The type of the currently displayed vector can be confirmed by viewing the setting of the stable mode.
Page 258 TT symbol display setting (TT Symbol Display) Turn on or off (ON / OFF) the TT symbol display. This function can be used only when the AIS display function (optional) is on. This function cannot be used when the AIS display function (The TT display function cannot be deactivated if only TT is used without using the AIS function).
Page 259: Tt Data Display
5.1 PREPARATION 5.1.3 TT Data Display (Refer to Example of Display in Section 2.1 “EXAMPLE OF DISPLAY.”) Display of Vectors Attention When a target or own ship changes a course, or when a target is acquired, its vector may not reach a given level of accuracy until three minutes or more has passed after such course change or target acquisition.
Page 260 Relative Vector Mode In displaying the relative vector of a target, press the [VECT R/T] key to select the Relative Vector mode. The relative vector does not represent the true motion of the target, but its relative relation with own ship. This means that a target with its relative vector directed to own ship (passing through the CPA LIMIT ring) will be a dangerous target.

Page 324 The radar operator has a role of interpreting the radar displays to provide his best aid in maneuvering the ship. For this purpose, the operator has to observe the radar displays after fully understanding the advantages and disadvantages that the radar has. For better interpretation of radar display, it is important to gain more experiences by operating the radar equipment in fair weathers and comparing the target ships watched with the naked eyes and their echoes on the radar display.
Page 325: Radar Wave With The Horizon
6.1 RADAR WAVE WITH THE HORIZON RADAR WAVE WITH THE HORIZON Radar beam radiation has the nature of propagating nearly along the curved surface of the earth. The propagation varies with the property of the air layer through which the radar beam propagates. In the normal propagation, the distance (D) of the radar wave to the horizon is approximately 10% longer than the distance to the optical horizon.
Page 326 D (nm) Height of Target Height of Radar Scanner Detective Range Figure 6.1 When the height of own ship’s scanner is 10 m for instance, A target that can be detected at the radar range of 64 nm on the radar display is required to have a height of 660 m or more.
Page 327: Strength Of Reflection From The Target
6.2 STRENGTH OF REFLECTION FROM THE TARGET STRENGTH OF REFLECTION FROM THE TARGET The signal intensity reflected from a target depends not only on the height and size of the target but also on its material and shape. The echo intensity from a higher and larger target is not always higher in general. In particular, the echo from a coast line is affected by the geographic conditions of the coast.

Page 332 [III] Coping with sea clutter and rain and snow clutter When the weather is bad and the ocean is rough, the use of an S band radar is effective because the radar is not influenced by sea clutter so much and attenuation due to rain drops is small. When an X band radar is used, reducing the pulse width will reduce the influence by spurious waves, and also the spurious wave rejection function effectively works;...
Page 333: False Echoes
6.4 FALSE ECHOES FALSE ECHOES The radar observer may be embarrassed with some echoes that do not exist actually. These false echoes appear by the following causes that are well known: [I] Shadow When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction of the funnel or mast cannot appear on the radar display because the radar beam is reflected on the funnel or mast.
Page 334 [IV] False Echo by Multiple Reflection When there is a large structure or ship with a high vertical surface near own ship as shown in Figure 6.7, multiple refection returns may appear on the radar display. These echoes appear in the same intervals, of which the nearest echo is the true echo of the target.
Page 335 6.4 FALSE ECHOES [VI] Radar Interference When another radar equipment using the same frequency band as that on own ship is near own ship, a radar interference pattern may appear on the radar display. This interference pattern consists of a number of spots which appear in various forms.
Page 336: Display Of Radar Transponder (Sart)
DISPLAY OF RADAR TRANSPONDER (SART) The SART (Search and rescue Radar Transponder) is a survival device authorized by the GMDSS (Global Maritime Distress and Safety System), which is used for locating survivors in case that a distress accident occurs at sea. The SART is designed to operate in the 9 GHz frequency band. When receiving the 9 GHz radar signal (interrogating signal) transmitted from the radar equipment on a rescue ship or search aircraft, the SART transmit a series of response signals to inform the distress position to the rescue and search party.
