  i PRECAUTIONS BEFORE OPERATION 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. (Maintenance, check-up and adjustment of the inside of the equipment are prohibited except by maintenance specialists. ) High voltages of tens of thousands volts are so dangerous as to bring a death from electric shock,  but  even  voltages  of  hundred  volts  may  sometimes  lead  to  a  death  from electric shock. To prevent such an accident, make it a rule to turn off the power switch, discharge capacitors  with  a  wire  surely  earthed on an end 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. In this case, it is necessary to perform an emergency measure immediately.
  ii FIRST-AID TREATMENTS  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 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 this 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.
  iii FIRST-AID TREATMENTS ■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. Take a deep breath  again and blow into his mouth.  Continue this 10 to 15 times a minutes (blocking his nostrils).  4    Carefully  watch  that  he  has  recovered  his  natural  breathing  and  atop 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 and keep  him warm and quiet. (Never give him alcoholic drinks. )   ●Method of mouth-to-mouth respiration by raising head    Fig. 1    Mouth-to mouth respiration  (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.
  iv FIRST-AID TREATMENTS ■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). (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  blow  into  his  mouth  twice,  and  they  shall  repeat  this  combination. (Perform the 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 hot coffee or  tea and keep  him  warm and calm  while  watching him carefully.  (Never  give him alcoholic  drinks.  )  Commit  the  victim  to  a  medical  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 treatment.   Fig. 2    Cardiac massage

  x PRECAUTINS PRECAUTIONS         Never carry out internal inspection or repair work of the equipment by users.   Inspection or repair work by unauthorized personnel may result in   fire hazard or electric shock.   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.   Failure to comply may result in electrocution.       Turn off the main power before cleaning the equipment. Especially when a rectifier is used, make sure to turn it off since voltage is   still output from the rectifier even after the radar is turned off. Failure to comply may result in equipment failure, electric shock or   serious injury.        When conducting maintenance work on the antenna, make sure to turn its main power off.   Failure to comply may result in electrocution or injuries.    DANGER
  xi PRECAUTINS    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.          Microwave radiation level:   Keep away from a scanner when it is transmitting.   The high level of microwave is radiated from the front face of the   scanner specified below. The microwave exposure at close range could result in injuries (especially of the eyes).      Make sure to install the antenna at a place higher than human   height.   Direct exposure to electromagnetic waves at close range will have adverse effects on the human body.       Direct exposure to electromagnetic waves at close range will have adverse effects on the human body. When it is necessary to get close to the antenna for maintenance or inspection purposes,   make sure to turn the indicator power switch to "OFF" or "STBY."   Direct exposure to electromagnetic waves at close range will have adverse effects on the human body.       When conducting maintenance work, make sure to turn off the power and unplug the power connector J1 of the display unit 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 without unplugging the power connector may result in electrocution, equipment failure, or accidents. WARNING
  xii PRECAUTINS      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.          If sensitivity is set too high, unnecessary signals such as noises in the receiver and false echoes increase to lower target visibility. At the same time, if sensitivity is set too low, detection of targets   such as ships and dangerous objects may be hindered.   Therefore, sensitivity must always be set to an optimal level.         When using the sea clutter suppression function, never set the suppression level too high  canceling  out all image noises  from  the sea surface  at close range. Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited.   When  using  the  sea  clutter  suppression  function, make  sure  to  choose  the most appropriate image noise suppression level.         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  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. Also, targets that are not detected by the radar cannot be acquired or tracked.   Making the final navigation decision based only on the radar display may cause accidents such as collisions or running aground.    CAUTION
  xiii PRECAUTINS    Target Tracking Function Test is provided to test if the target   tracking function is operating normally. Thus, do not use the function except when you test the target tracking function. Note especially that, if this function is used during actual navigation, simulated targets are displayed and may become confused with other actual targets. Therefore, never use this function during actual navigation.  When a large value is set as an association 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 the cargo vessel may disappear.  Since these alarms may include some errors depending on the   target tracking conditions, the navigation officer himself should   make the final decision for ship operations such as collision avoidance. Making the final navigation decision based only on the alarm may cause accidents such as collisions.  When setting an automatic acquisition 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 automatic acquisition zone alarm will not be activated for targets undetected by the   radar, and it may result in accidents such as collisions.  Any adjustments must be made by specialized service personnel. Incorrect settings may result in unstable operation.   Do not make any adjustments during navigation. Failure to comply may result in adverse effects on the radar function which may lead   to accidents or equipment failure.  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.    CAUTION
  xiv PRECAUTINS      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. Failure to comply may result in electrocution.    Make sure to take off your watch when your hand must get close to the magnetron.   Failure to comply may result in damage to the watch since the magnetron is a strong magnet.    When cleaning the display screen, do not wipe it too strongly with a dry cloth. Also, do not use gasoline or thinner to clean the screen.   Failure to comply will result in damage to the screen surface.           CAUTION

  Chapter 1    INSTALLATION 12  1-3 INSTALLATION OF THE SCANNER UNIT 1-3-1 SELECTING THE INSTALLATION POSITION ■ PHYSICAL SELECTION CRITERIA ■ Install the scanner at the center of the mast on the keel line. ■ If the scanner cannot be installed at the above position for some reason, the amount of deviation must be minimized. And, reinforce the mount base and the platform and take precautions to protect the scanner from vibration and impact at the installation position. ■ There needs to be no influence of the dust by smoke from a chimney.   ■ Please secure maintenance spaces (a platform, a safety link, a handrail, a step, etc.). ■ ELECTRICAL SELECTION CRITERIA ■ The installation height of the scanner relates to the maximum detection distance.   The higher, the better. However, if it is too high, radio wave energy greatly attenuates above the scanner's vertical beam width (the point -3 dB from the peak of the main-lobe). As a result, it is difficult to detect a close-in target. Sea clutter also increases. Determine the installation height by taking into consideration the weight, maximum length of the cable, and maintenance after installation. If the installation height of the scanner is low, it is difficult to detect a long distance target. The ship's mast, derrick, and chimney interfere with radiating beam causing the range that cannot be viewed on the radar display to increase. Generally, the lowest scanner installation position is supposed to be on the A-B line shown in Fig. 1-3-2. In the case of the JMA-1030 type radar, 2θ equals 25°. Specifically, the scanner position is normally elevated so that the chimney and the shrine-gate type mast do not interfere with radiating beam.
  Chapter 1    INSTALLATION 13  1-3-2 LOWEST SCANNER INSTALLATION HEIGHT JMA-1030 : θ= 12.5 °  2θ= 25 °            Fig. 1-3-2 ■ If it is considered that sufficient installation height cannot be provided when the scanner is installed directly on the roof of the wheelhouse, use a mounting rack or radar mast (Fig. 2.1-3). Normally, when the scanner installation height is less than 2 meters from the roof of the wheelhouse, provide a mounting rack assembled at an angle frame to install the scanner. When the scanner installation height is 2 m or higher from the roof of the wheelhouse, provide a cylindrical radar mast to install the scanner. Consider the convenience of the service staff who take care of installation, maintenance, adjustment, and repair of the scanner by providing adequate footholds to the mounting rack and the radar mast  1-3-3 MOUNTING RACK AND MAST FOR THE SCANNER           Fig. 1-3-3  ■ When installing the scanner, select a location where there are the fewest structural objects in the surrounding area so that false images which interfere with target detection will not be generated by signal reflection from other scanners, deck structures, and cargo. Only as a guide, note that structural objects should not exist within the range of the vertical beam width (Fig. 1-3-4).      Installation  Installation
  Chapter 1    INSTALLATION 14  1-3-4 SCANNER AND THE SURROUNDING STRUCTURAL OBJECTS  Vertical beam width of X-band: Approx. 20° (+/-10.0° when the height of the radiating section is 0°).           Fig. 1-3-4  When installing two scanners, provide a height difference so that those two scanners do not enter each other's vertical beam width range. To avoid interference with other equipment and to prevent radio noise from generating, do not place the VHF antenna, GPS antenna, and INMARSAT's dome within the range of the vertical beam width. Keep a record of installation height data. The data is necessary for the initial setting of the display unit.  ■ Minimize the blind sector, and ensure the adequate view angle so that the blind sector does not exist in the range 22.5° from side to rear (Fig. 1-3-5). Specifically, ensure a sufficient view field in the straight front (relative bearing 000°).
  Chapter 1    INSTALLATION 15  1-3-5 ENSURING VIEW ANGLE          Fig. 1-3-5  ■ Magnetron which has strong magnetic force is included in the scanner. Install the scanner at least 3 meters away from nautical instruments including magnetic compasses and chronometers.  * If there is a concern that structural objects existing within the vertical beam width may generate false images, equip the structural objects with a radio wave absorber. (There are two types of absorbers: broadband type having no specific resonant frequency and narrowband type which can absorb a band with a specific frequency. Use those where applicable.) Furthermore, it is effective to install a metal reflector, which reflects radio waves upwardly, between the scanner and a structural object so that the radar's radio wave will not directly come in contact with the structural object   Reference: ■ Because most radio wave absorbers have poor durability, some must be replaced every year. When installing a reflector, the area to the rear of the reflector becomes a blind sector. Therefore, minimize the size of the reflector. ■ The above procedures for selecting an scanner installation position are described based on the radar's scanner. Comprehensively select the scanner position by considering other scanners' installation procedure manual, hull's structure, strength of the selected position, and vibration.  ■ Confirmation during test run If the scanner vibrates a lot during test run, try to reduce or prevent vibration by reinforcing the scanner mount base or using wire stays attached to the radar mast.  direction Make no blind sector
  Chapter 1    INSTALLATION 16  ■ Others ■ The design of the mounting platform for the scanner should take into account the vibration requirements defined by IEC 60945. Vibration Frequency  2 to 13.2 Hz 13.2 Hz to 100 Hz Amplitude  +/-1 mm +/-10 % Acceleration 7m/s2 constant  ■ All installations should facilitate protection of equipment, including cabling, from damage. ■ The cables should be kept as short as possible to minimize attenuation of the signal. ■ Crossing of cables should be done at right angles(90°) to minimize magnetic field coupling. ■ Install the radar cable as far as from the cables of other radio equipment in order to prevent other radio equipment from interfering with the radar operations. Especially inter-wiring cables between scanner unit and display unit of the radar should not be run parallel with the cables of other radio equipment. ■ Cable should not be exposed sharp bends. ■ Ensure that the equipment is grounded.   ■Maintain a flat level surface on which to install the scanner. ■ Use sufficiently thick steel material and reinforcement material for the scanner's installation surface (mount base) to reduce vibration and impact. Keep the mount base flat and smooth. ■ If there is a partial gap between the mount base and the scanner chassis's legs, work on the installation surface so that it becomes flat and smooth, or make adjustments by inserting metal shims. If a gap exists and the scanner is tightly clamped, the chassis will distort and become damaged by vibration. ■Avoid using vibration-proof rubber and resin ■ Do not insert an elastic body, such as vibration-proof rubber or resin, between the mount base and the scanner chassis' legs. If rubber or resin is inserted, the amplitude of vibration increases, resulting in the possibility of damage to the scanner. Furthermore, if installation bolts become loose due to deterioration of rubber or resin, the scanner may be damaged or fall from its mount

  Chapter 1    INSTALLATION 19  ■ Installation and clamping method ■ Installation direction Installation should be done so that the cable gland is oriented toward the stern. ■ Bolts, nuts and tightening torque to be used ■ Use stainless steel bolts for the scanner and uniformly tighten all of the bolts using double nuts for each bolt so that the scanner will not become loose (Table 1-2-1). ■ Although the length of the bolt will differ according to the thickness of the mount base, use a bolt long enough so that more than 4 millimeters of thread protrudes beyond the double nuts after the double nuts have been tightened.  Table 1-3-6-1 Length of scanner mounting bolts and tightening torque Thickness of Mount Base (mm) Bolt  Torque (N-m) 3-15 mm      (Recommend) M8X30SUS (attachment)     20    N-m    ■ Use of washer and corrosion-resistant measures ■ At the location where a bolt's head or nut comes in contact with the scanner chassis' legs and the mount base, insert a plain washer which fits the bolt; and, at the location where the nut comes in contact with the plain washer, insert a spring washer, and then securely tighten the nuts . ■ To prevent corrosion due to the contacts between different metals, such as the scanner chassis' legs, installation surface, bolts, nuts, etc., cover the bolt's head and nuts with sealant .  ■ Grounding and corrosion-resistant measures ■ Do not install the scanner in place where puddles are often formed.
  Chapter 1    INSTALLATION 20  1-4 CONNECTING THE INSTALLATION CABLE   Scanner type is selected from two types. 2 ft scanner (NKE-2044) ,and 1.5 ft scanner(NKE-1066).   Both are the radome type, they are no affect from the wind blow. Because inside microwave radiator is protected by fixed radome.   Even under the strong wind blow conditions, microwave radiator can rotate stable anytime.  The cable’s both ends is already processed in factory. First step, remove radome and connect the cables as follow. Open cover, and connect as follows.
