Page 3 ◆◆◆PRECAUTIONS BEFORE OPERATION◆◆◆ ■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.
Page 4 ◆◆◆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.
Page 5 ☆When pulse is beating but breathing has stopped (Mouth-to-mouth respiration) Fig. 1 (1) Tilt the victim’s head back as far as this face looks back. (A pillow may be inserted 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.
Page 6 ☆When both pulse and breathing have stopped Perform the (Cardiac massage) Fig. 2 and (Mouth-to-mouth respiration) Fig. 1 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 minutes).

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. Normally, use the automatic tune mode. Use the manual tune mode only when best tuning is not possible in the automatic tune mode due to deterioration of magnetron.
Page 13 CAUTION Use the radar 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 radar display may cause accidents such as collisions or running aground. Use target tracking function only as a navigation aid.
Page 14 CAUTION If a great value is set as a condition for deciding targets as identical, a tracking target near an AIS target is regarded as identical to the AIS target and it may not be displayed any more. For example, when a pilot boat (which is a small target not being tracked) equipped with an AIS function approaches a cargo ship as a tracking target not equipped with an AIS function, the tracking target symbol of the cargo ship may...
Page 15 CAUTION Any adjustments must be made by specialized service personnel. Failure to comply may result in accidents or equipment failure. Make sure to shut off the main power before replacing parts. Failure to comply may result in electrocution or equipment failure. When replacing magnetrons, make sure to shut off the main power and let the equipment stand for more than 5 minutes to discharge the high-voltage circuit.

Page 252: 5.1.1 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: Basic Concept Of Collision Avoidance
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
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 308: Trial Maneuvering (Trial Maneuver)
TRIAL MANEUVERING (TRIAL MANEUVER) Attention Trial maneuvering is to simulate own ship’s course and speed in the conditions that the course and speed of a target ship are unchanged as they are. As the situation is different from any actual ship maneuvering, set values with large margins to CPA Limit and TCPA Limit.
Page 309: Trial Maneuvering In The True Vector Mode
5.7 Trial Maneuvering Trial Maneuvering in the True Vector Mode In the True Vector mode, calculations are performed according to the values set by Trial Speed, Trial Course and other features, and the result is displayed as a bold-line that represents the change of own ship’s vector as shown in the figure below (an example of the course changed to the right).
Page 310: Trial Maneuvering In The Relative Vector Mode
Trial Maneuvering in the Relative Vector Mode The result of Trial maneuvering in the Relative Vector mode is shown by a change in target vector. In the figure below (in the same conditions as in the True Vector mode in the previous page), it is seen that the acquired target is a dangerous one because its vector is crossing the CPA RING.

Page 318: Radar Wave With The Horizon
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 319 6.1 Radar Wave with the Horizon D (nm) Detective Range Height of Target Height of Radar Scanner 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 320: 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 322: Sea Clutter And Rain And Snow Clutter
SEA CLUTTER AND RAIN AND SNOW CLUTTER In addition to the echo required for observing ships and land radar video image also includes unnecessary echo, such as reflection from waves on the sea surface and reflection from rain and snow. Reflection from the sea surface is called "sea clutter,"...
Page 323 6.3 Sea Clutter and Rain and Snow Clutter As shown in Table 6.3, the number of SS increases as the wind speed becomes high and the waves become large. Table 6.2 reveals that detection probability decreases from V (80 %) to NV (less than 50 %) as the number of SS increases.

Page 325 6.3 Sea Clutter and Rain and Snow Clutter [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 326: 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 327 6.4 False Echoes [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 328 [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. In many cases, these spots do not always appear at the same places, so that they can be discriminated from the target echoes.
Page 329: Display Of Radar Transponder (Sart)
6.5 Display of Radar Transponder 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.
Page 330 [Example of Display] Attention When the SART function is set to ON, small targets around own ship will disappear from the radar display. So it is necessary to exercise full surveillance over the conditions around own ship by visual watch in order to avoid any collision or stranding. If two or more sets of radar equipment are installed on own ship, use one set of 9 GHz band radar for detection of the SART signal and operate others as normal radars for avoiding collision,...
Page 331: Display Of Ais-Sart
6.5 Display of Radar Transponder DISPLAY OF AIS-SART AIS Process Unit (option) is necessary. AIS-SART is an equipment to display the position of distress ship on the AIS indicator in ship station or coast station when the distress occurs. It is usable as an alternate equipment of SART(Search And Rescue Transponder). When connecting AIS indicator to RADAR, it is possible to display AIS-SART symbol on the RADAR screen.
Page 332 [II] Numeric Display When the sleeping AIS-SART symbol is clicked once, the symbol changes into activated AIS-SART symbol. And then activated AIS-SART symbol is clicked once more, the symbol changes into numeric displayed AIS-SART symbol and their information is displayed.
