Page 3 Cautions for High Voltage High voltages, ranging from several hundreds to tens of thousands of volts, are used in electronic apparatus, such as radio and radar instruments. These voltages are totally harmless in most operations. However, touching a component inside the unit is very dangerous. (Any person other than authorized service engineers should not service, inspect, or adjust the unit.) High voltages on the order of tens of thousand volts are most likely to cause instant deaths from electrical shocks.
Page 4 Method of First-Aid Treatment ☆Precautions for First-Aid Treatments Whenever a person is struck by an electrical shock, give the patient artificial respiration immediately on the spot, unless it is absolutely necessary to move the patient for safety's sake. Once started, artificial respiration should be continued rhythmically.
Page 5 ☆Treatment to Give When the Patient Has a Pulse Beating but Has Ceased to Breathe ＊Performing mouth-to-mouth artificial respiration - Fig. 1 Bend the patient's face backward until it is directed to look back. (A pillow may be placed under the neck.) Pull up the lower jaw to open up the airway.
Page 6 ☆Treatment to Give When the Patient Has No Pulse Beating and Has Ceased to Breathe ＊Performing cardiac massage - Fig. 2 If the patient has no pulse beating, with the pupils open and no heartbeat being heard, the patient has a cardiac arrest and requires immediate artificial respiration.

Page 9: Precautions
●PRECAUTIONS● DANGER Never conduct inspection or repair work of equipment componts. Inspection or repair work by uncertified personnel may result in fire hazard or electric shock. For inspection and repair work of equipment components, consult with our branch office, branch shop, salea office, or our distributor in your district.
Page 10 WARNING Never directly touch the internal components of the scanner or indicator. Diect contact with these high-voltage components may cause electric shock. For maintenace, inspection, or adjustment of equipment components, consult with our branch office, branch shop, sales office, or our distributor in your district. To contact our sales department, branch offices, branch shops, and sales offecs: Prese refer to the “Office List”...
Page 11 WARNING When conducting maintenance work, make sure to turn off the power so that the power supply to the equipment is completely cut off. Some equipment components can carry electrical current even after the power switch is turned off, and conducting maintenance work may result in electric shock, equipment failure, or accidents.
Page 12 WARNING Do not insert and remove the USB device while transmitting. The radar image becomes unstable by accessing the USB device not acticipated, and it causes the breakdown.
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 (TT) function only as a navigation aid.
Page 14 CAUTION When setting a guard zone, make sure to properly adjust gain, sea-surface reflection suppression level, and rain/snow reflection suppression level so that the optimal target images are always on the radar screen. The guard zone alarm will not be activated for targets undetected by the radar, and it may result in accidents such as collisions.
Page 15 CAUTION Do not directly touch the inverter circuit of the LCD display with a bare hand since high voltage temporarily remains in the circuit even after the main power is shut off. Failure may result in electric shock. Any adjustments must be made by specialized service personnel. Incorrect settings may result in unstable operation.

Page 242: 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 243: 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 244: 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.

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 305 6.1 Radar Wave With The Horizon D (nm) Height of Target Height of Radar Scanner Detective Range Figure 6.2 Maximum radar range 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 306: 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 310 [II] Rain and snow clutter Rain and snow clutter is a video image that appears in a location where rain or snow is falling. The image changes according to the amount of rain (or the amount of snowfall). As precipitation increases, the image of rain and snow clutter becomes intensified on the radar display, and in the case of localized heavy rain, an image similar to the image indicating land is displayed in some cases.

Page 312: 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 313 6.4 False Echoes [III] False Echo by Secondary Reflection When a target exists near own ship, two echoes from the single target may appear on the radar display. One of those echoes is the direct echo return from the target and the other is the secondary reflection return from a mast or funnel that stands in the same direction as shown in Figure 6.7 Direct microwave Actual target...
Page 314 [V] Second Time Echoes The maximum radar detection range depends upon the height of the scanner and the height of a target as described in the section “6.1 RADAR WAVE WITH THE HORIZON”. If a so-called “duct” occurs on the sea surface due to a certain weather condition, however, the radar beam may propagate to a abnormally long distance, at which a target may be detected by the radar.

Page 316 (The position of a SART is indicated as one line of 12 bright points.) [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.

Page 398: Fault Finding
FAULT FINDING In case of semiconductor circuits, it is deemed that there are few cases in which the used semiconductor devices have inferior quality or performance deterioration except due to insufficient design or inspection or by other external and artificial causes. In general, the relatively many causes are disconnection in a high-value resistor due to moisture, a defective variable resistor and poor contact of a switch or relay.
