V ●●●●Cautions to be used during operation●●●● Do not touch the insides of the scanner unit, transceiver and display unit. Touching any high voltage area, you will get an electric shock. For maintenance, inspection and adjustment of internal parts of these equipment, consult with our sales office or distributor in your district. Since the scanner unit radiator rotates, do not approach it. The scanner unit may start rotating suddenly, and consequently any person may be struck and be injured. We recommend you to install the scanner unit radiator on the roof of the wheel house, flying bridge, trestle, radar mast or any other high position so that no person can approach it. When servicing the scanner unit, set the scanner unit safety button to the OFF position. Install the scanner unit at any place higher than any person. If being exposed directly to electric wave at close range, you may suffer adverse influence. When approaching the antenna for maintenance or inspection, set the power button of the display unit to the ST-BY position. If being exposed directly to electric wave at close range, you may suffer adverse influence. WARNING CAUTION Use these radar only as assisting devices for navigation. Also, the officer should make the final decision for maneuvering by himself. If you make the final decision of maneuvering only on the information which a radar display, it may become the cause of accidents, such as collision and stranding.
VI ──ご使用前に注意してご使用前に注意してご使用前に注意してご使用前に注意していただきたいいただきたいいただきたいいただきたいことことことこと── 高電圧に対する注意高電圧に対する注意高電圧に対する注意高電圧に対する注意 無線装置、レーダなどの電子機器の内部には数百から数万ボルトの高電圧が使用されています。通常の操作においてはまったく危険はありませんが、万一、誤って機器内部に触れた場合非常な危険を伴います。（専門整備員以外の機器内部の保守・点検・調整は禁止） 数万ボルトの高圧では感電即死の危険が大きく、また時により数百ボルトの電圧でも感電死することがあります。このような危険を防止するには機器の内部に手を入れるとき、必ず電源スイッチを切って、一端を確実に接地した電源でコンデンサーなどを放電させ、電気の残っていないことを確めた上で初めて手を内部に入れるようにしてください。この際、乾燥した木綿の手袋などを用いればなおいっそう危険防止となります。また左手をポケットに入れ、両手を同時に用いないことも必要な注意の一つです。感電したときの障害は二次的に大きくなることがあるので足場もしっかりした所を選ぶことが大切です。感電したときは火傷した所を完全に消毒して、手当を速やかに行うことが必要です。 電撃の救出上の注意電撃の救出上の注意電撃の救出上の注意電撃の救出上の注意 電撃を受けた人を発見した場合、直ちに電源を切り回路を接地してください。回路が直ちに切れないときは、感電した人をできるだけ早く乾いた板、布などの絶縁物を介して直接感電した人に触れずに離してください。 感電したとき、頭脳の呼吸中枢に電流が流れると呼吸が急に止まります。衝撃があまりひどくないときは人工呼吸を行うことにより呼吸を回復します。電撃を受けた人は非常に顔色が悪くなり、脈が大変弱くなってしまうか、まったく止まってしまうことがあり、人事不省になり硬直します。
VII ──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. (Authorized maintenance personnel alone are permitted to implement maintenance, check-ups or adjustment of internal components.) High voltages of tens of thousands volts are so dangerous as to bring an instantaneous death from electric shock, but even voltages of hundreds volts may sometimes lead to a death from electric shock. To prevent such an accident, make it a rule to turn off the power button, discharge capacitors with a wire surely earthed on an end and 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.

IX 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 certainly 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 his 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 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, close his mouth so that foaming mucus does not accumulate inside.
X ☆脈拍があり呼吸していない場合の処置☆脈拍があり呼吸していない場合の処置☆脈拍があり呼吸していない場合の処置☆脈拍があり呼吸していない場合の処置 （1）患者の顔が後を見る位に顔をそり返らせる（頸部に枕を挿入してもよい）。 （2）下顎を上方に引き上げ気道を広げる（気道拡大）。 （3）患者の鼻をつまみ、術者は深く息を吸い患者の口を完全に塞ぐようにして強く呼気を吹き込む。再び口を離して息を大きく吸って吹き込む。 1分間に約10回から15回くり返す（鼻腔を塞ぐこと）。 （4）自然に呼吸の起きるのを注意しながら呼吸が戻ったときに止める。 （5）開口困難な場合ゴム、ビニールなどのパイプ状のものを鼻腔に挿入して片方の鼻腔と口を完全に塞いで息を大きく吸って吹き込む。 （6）患者は気が付くといきなり立つ事がありますが静かに寝かせ、熱いコーヒー、紅茶などを与え暖かくして安静を保つ（アルコール類は与えてはならない）。 頭部をもたげて口うつし人工呼吸を行う方法頭部をもたげて口うつし人工呼吸を行う方法頭部をもたげて口うつし人工呼吸を行う方法頭部をもたげて口うつし人工呼吸を行う方法 ③②①(1)後頭部をもたげ、片方を額に他の手を頸部の下にあてる。→ ①多くの患者はこの頭部のもたげにより口が開き空気が通じ、口うつしが容易になる。(2)患者の口をあなたの口で広く封じ、あなたの頬を患者の鼻に押しあてる。→②または、あなたの指で患者の鼻を押さえて空気の漏れを防ぐ。→ ③(3)胸があがるまで口から空気を肺内に吹き込む。最初の10回の呼気吹き込みはできるだけ急速度で行わなければならない。 図１ 口うつし人工呼吸法
XI ☆☆☆☆When pulse is beating but breathing has stopped (1) Tilt the victim's head back as far as this face looks back. (A pillow may be inserted under 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 minute (blocking his nostrils). (4) Carefully watch that he has recovered his natural breathing and stop 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 to keep him warm and quiet. (Never give him alcoholic drinks.) Method of mouth-to-mouth respiration by raising head Fig.1 Mouth-to-mouth respiration③②①(1) Raise the victim's head. Support hisforehead with one of your hand and hisneck with the other hand. → ①When you tilt his head backward, thevictim, in most cases, opens his mouth tothe air. This makes mouth-to-mouthrespiration easy.(2) Cover his mouth as widely as possiblewith yours and press your cheek againsthis nose → ② , or, pinch his nostrilswith your fingers to prevent air fromleaking. → ③ (3) Blow into his lungs.Continue blowing into his mouth until hisbreast swells. Blow into his mouth asquickly as possible for the first 10 times.
XII ☆脈拍なく呼吸もしていない場合の処置☆脈拍なく呼吸もしていない場合の処置☆脈拍なく呼吸もしていない場合の処置☆脈拍なく呼吸もしていない場合の処置 脈拍がなく、瞳孔が開き、心臓に耳を当てても鼓動が聞かれない場合は、心臓が停止しているので速やかに人工呼吸を行う必要があります。 （1）胸骨の下1/3の部位に両手を重ね肘を伸ばして（曲げているとくぼむほど押せません）、術者の体重をかけ約2cm位くぼむように圧迫する（1分間に約50回位くりかえす）。 （心臓マッサージ法） （2）1人で救急処理を行う場合は、 15回位心臓マッサージを行い速やかに２回呼気を吹き込む。これをくり返す。 2人で救急処理を行う場合は、 1人が5回心臓マッサージを行い、その間に他の1人が1回呼気を吹き込む。これをくり返す。 （心臓マッサージ法と口うつし人工呼吸法の併用） （3）時々瞳孔を見たり、脈に触れてみる。瞳孔が正常となり脈も規則正しくなったら、各手当てを中止して様子を見ながらコーヒー、紅茶などを飲ませ暖かくし安静を保つ。いずれにしても、経過の判断は専門医に任せる。特に、精神的ショックより早く復帰させるように周囲の理解が必要です。 ①②③④図２　心臓マッサージ法
XIII ☆☆☆☆When both pulse and breathing have stopped 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 minute). (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 5 times while the other person blows into his mouth once, and they shall repeat this combination. (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 coffee or tea and keep him warm and calm while watching him carefully. Commit the victim to a medial 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 treatments. ①②③④Fig.2 Cardiac massage

145 1 Introduction 1.1 Function The JMA-2243/2344 series radar devices are marine radar devices that use scanner units including transmitter and receiver and 10 inch monochrome cathode-ray tube utilizing the compact raster scan method for achieving a fully semi-conductor adopted (excluding special electron tubes) system. This equipment comprises radar as defined in the Wireless Telegraphy Act. 1.2 Features Enhanced fundamental performance of the radar Through switching among 4 steps in terms of pulse width/cycle switching of frequency and switching among 3 steps in receiver bandwidth, enhanced fundamental performance of the radar has been achieved towards display of clearer and higher quality images. Moreover, through the incorporation of advanced digital signal processing, performance in target de-tection during increment weather has been improved. Confirmation of the ship's position and identifying the waypoint at a glance Through connecting to navigation equipment such as GPS, the location of the ship (nu-merical value) or a mark on the waypoint may be displayed on the screen and through this, the difference between the bearing of the waypoint and the ship's heading may be grasped at a glance. High operability EBL and VRM that are frequently used are equipped with dedicated switches. Moreover, 4 soft key switches have been incorporated and functions that are relatively frequently used may be operated with ease. Additionally, a system for selecting functions that are infre-quently used from the menu has been adopted.

173 3.3.9 In the event of rain or snow CAUTION Refrain from setting the rain and snow clutter suppression function needlessly. Doing so may suppress echoes from targets such as other vessels for hazardous objects in addition to echoes from rain and snow thus impairing detection. When using the rain and snow clutter suppression function, ensure that the suppression setting is always at an optimal level. When rain or snow falls, echo from the rain or snow (rain clutter) appears on the PPI screen making it difficult to see images of echoes from vessels or other objects. By using the [RAIN] control function or the "automatic rain and snow" function, rain clutter may be suppressed facilitating monitoring of the target. When the "automatic rain and snow" function is operating, it is not possible to use the [RAIN] control function.
