    ──ABOUT YOUR SAFETY── 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.

    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)...

  • Page 4

    ☆ ☆ ☆ ☆ When pulse is beating but breathing has stopped Tilt the victim's head back as far as this face looks back. (A pillow may be inserted under his neck.) Push his jaw upward to open his throat wide (to spread his airway). Pinch the victim's nostrils and take a deep breath, block his mouth completely with yours and blow into his mouth strongly.

    ☆ ☆ ☆ ☆ 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. 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).

    ● ● ● ● Cautions to be used during operation● ● ● ● The customer should refrain from inspecting or repairing the internal parts of this equipment. Inspection or repair other than by specialized service personnel may cause death or a serious injury of any person. Please contact the sales department of Japan Radio Co., Ltd.

    Make sure that the main power is turned off before maintaining the equipment. In particular, when a rectifier is used, a voltage is output from the rectifier even if the power of the display is turned off and the radar is stopped. If maintenance work is performed without turning off the main power, there is a risk of equipments breaking down, and dying or getting a serious injury of any person by electric shock.

  • Page 10

    Do not touch the insides of the scanner unit, transceiver and display unit. Touching any high voltage area, you will get an electric shock. 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.

  • Page 11

    Only specialized personnel shall perform installation work. Installation work performed by personnel other than specialized personnel may cause breakdown of the equipment, poor performance, fire, severe elec-tric shock and other property and human damages. When you directly connect with the ship's power supply without using the optional rectifier, measure the voltage between the hull's earth and the positive side of ship's power spply, and the hull's earth and the negative side of this.

    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.

    The processing unit is not waterproof. Use correct fuse ratings. The use of incorrect ratings may cause an equipment failure. The GPS compass JLR-10 of JRC always can output absolute azimuth without gyro setting. Therefore, do not set a gyro value when connecting JLR-10.

    Chapter 4 How to Interpret the PPI Screen 4.1 Height of and the Distance to the Target The maximum distance to a target that can be observed with a radar depends not only on the power of the radar's transmitter, beam width of the scanner unit, and the receiver's sensitivity but also on height of a target, distance to a target and height of scanner unit line etc.

  • Page 115: Returns From A Target, Propagation Path Of Radio Waves

    4.2 Returns from a Target The intensity of returns from a target is related not only to the size of the target but also to the materials and shape of the components making up the target. Accordingly, larger objects do not necessarily develop strong returns.

  • Page 116: Sea Returns, False Echoes

    4.3.1 Sea returns On a wavy sea surface, an echo appears on the PPI screen as a bright defused image at the center of the screen. This echo is developed by returns from the sea surface. The features of the echo depend on the size and range of the wave, and the wind direction.

  • Page 117

    (d) Multiple echo Multiple echoes are developed by multiple reflections caused by a building or large vessels that has large vertical surfaces. These echoes are spaced at an equal interval, with the one that is closest to the own ship being the true echo. (e) Radar interference If there is a radar that uses the same frequency as that of the own ship near the own ship, interferences caused by that radar appear on the PPI screen.

    4.4 Display of Radar Transponder SART (Search and Rescue Radar Transponder) is life preserving device approved by GMDSS which is used for locating survivors in the event of a disaster or distress. SART operates in the 9GHz frequency band. When it receives a radar signal (interrogating radio wave) of 9GHz transmitted by a rescue ship or aircraft radar, SART transmits a series of respouse signals to the searchers to indicate the distress position.

    9.3.10 Connecting a GPS compass (JLR-10) A MARPA unit, which is an optional unit, can be used by connecting GPS compass JLR-10 of JRC. 1. Using a dedicated cable JLR-10 can be connected easily by using the CFQ-6934 dedicated cable of JRC. This cable enables not only receiving of azimuth information from JLR-10 but also receiving of longitude and latitude information as NMEA data.

  • Page 162

    J5. To input NMEA data such as position information from the GPS equipment of JRC or a different manufacturer by acquiring azimuth data from JLR-10, connect a cable from GPS equipment using the connection method that is described in 9.3.9, "Connecting a GPS receiver and NMEA equipment"...

    9.3.11 Connecting an electromagnetic compass Caution ● ● ● ● Make correctly connection between the output of ship's power and rectifier unit, and power cable. If neither connection nor voltage is right, it may cause an equipment failure. Azimuth information can be input to a radar indicator unit if the electromagnetic compass is equipped with a NMEA0183 output pin.
