MF/HF RADIO EQUIPMENT Instruction Manual 7ZPJD0622

CAUTIONS AGAINST HIGH VOLTAGE Radio and radar devices are operated by high voltages of anywhere from a few hundred volts up to many hundreds of thousands of volts. Although there is no danger with normal use, it is very dangerous if contact is made with the internal parts of these devices. (Only specialists should attempt any maintenance, checking or adjusting.) There is a very high risk of death by even a few thousand volts, in some cases you can be fatally electrocuted by just a few hundred volts. To prevent accidents, you should avoid contact with the internal parts of these devices at all costs. If contact is inevitable as in the case of an emergency, you must switch off the devices and ground a terminal in order to discharge the capacitors. After making certain that all the electricity is discharged, only then can you insert your hand into the device. Wearing cotton gloves and putting your left hand in your pocket, in order not to use both hands simultaneously, are also very good methods of shock prevention. Quite often, an injury occurs by secondary factors, therefore it is necessary to choose a sturdy and level working surface. If someone is electrocuted it is necessary to thoroughly disinfect the affected area and seek medical attention as soon as possible. When you find an electrocution victim, you must first switch off the machinery and ground all circuits. If you are unable to cut off the machinery, move the victim away from it using a non-conductive material such as dry boards or clothing. When someone is electrocuted, and the electrical current reaches the breathing synapses of the central nervous system inside the brain, breathing stops. If the victim's condition is stable, he or she can be administered artificial respiration. An electrocution victim becomes very pale, and their pulse can be very weak or even stop, consequently losing consciousness and becoming stiff. Administration of first aid is critical in this situation. Cautions concerning treatment of electrocution victims

First aid ☆Note points for first aid Unless there is impending danger leave the victim where he or she is, then begin artificial respiration. Once you begin artificial respiration, you must continue without losing rhythm. (1) Make contact with the victim cautiously, there is a risk that you may get electrocuted. (2) Switch off the machinery and then move the victim away slowly if you must. (3) Inform someone immediately (a hospital or doctor, dial emergency numbers, etc.). (4) Lay the victim on his or her back and loosen any constrictive clothing (a tie, or belt). (5) (a) Check the victim's pulse. (b) Check for a heartbeat by pressing your ear against the victim's chest. (c) Check if the victim is breathing by putting the back of your hand or face near the victim's face. (d) Check the pupils of the eyes. (6) Open the victim's mouth and remove any artificial teeth, cigarette or chewing gum. Leave the mouth opened and flatten the tongue with a towel or by putting something into the mouth to prevent the victim's tongue from obstructing the throat. (If he or she is clenching the teeth and it is difficult to open the mouth, use a spoon or the like to pry open the mouth.) (7) Continually wipe the mouth to prevent the accumulation of saliva.

☆If the victim has a pulse but is not breathing (“Mouth to mouth” resuscitation) Figure 1 (1) Place the victim’s head facing backward (place something under the neck like a pillow). (2) Point the chin upward to widen the trachea. (3) Pinch the victim’s nose, take a deep breath, then put your mouth over the victim’s mouth and exhale completely, making sure that your mouth completely covers the victim’s mouth. Then remove your mouth. Repeat this routine 10 to 15 times per minute (holding the nostrils). (4) Pay attention to the victim to notice if he or she starts to breath. If breathing returns, stop resuscitation. (5) If it is impossible to open the victim’s mouth, put something like a plastic straw or vinyl tube into one of the nostrils then blow air in while covering the mouth and the other nostril. (6) Occasionally, when the victim comes back to consciousness, they immediately try to stand up. Prevent this and keep them in a laying position. Give them something warm to drink and be sure that they rest (do not give them any alcohol). Administering artificial respiration by raising the head. ① (1) Raise the back of head, then place one hand on the forehead and place the other hand under the neck. →① Most victims open their mouth when this is done, making “mouth to mouth” resuscitation easier. ② (2) Cover the victim’s mouth by opening your mouth widely, then push your cheek against the victim’s nose, →② or pinch the victim’s nose to prevent air from leaking out of it. →③ ③ (3) Completely exhale into the lungs. Exhale into the lungs until the chest inflates. You have to blow as rapidly as possible for the first 10 times. “Mouse to mouse” artificial respiration Figure 1

☆If the victim has no pulse and is not breathing (Heart massage in combination with artificial respiration.) Figure 2 If the victim has no pulse, his or her pupils are dilated, and if you cannot detect a heartbeat, the heart may have stopped, beginning artificial respiration is critical. (1) Put both hands on the diaphragm, with hands on top of each other keeping both arms straight (If your elbows are bent, you cannot push with as much power). Press the diaphragm with your body weight until the chest sinks about 2 cm (about 50 times per minute). (2) If administering first aid when alone: Perform the heart massage about 15 times then blow in twice. Repeat this routine. If administering first aid with two people: One person performs the heart massage 5 times, and the other person blows air in once. Repeat this routine (Heart massage and “mouth to mouth” resuscitation used together). (3) Constantly check the pupils and the pulse, if the pupils become normal and the pulse steadies, keep them in a laying position and give them something warm to drink, be sure that they rest (do not give them any alcohol). In any case you have to entrust major decision making to a doctor. Having understanding people around is essential to the victim’s recovery from the mental shock of electrocution. ① ② ③ ④ (Heart massage in combination with artificial respiration.) Figure 2

Equipment Overview 1-1 1. EQUIPMENT OVERVIEW 1.1 Functions This equipment includes MF/HF transceiver, Class-A DSC and DSC watch keeping receiver required as the Global Maritime Distress and Safety System (GMDSS). It is designed as a separated transceiver and small, lightweight controller(s) for easy installation not only in SOLAS Convention ships such as international passenger ships and freight ships of 300 tons or more, but also non-conventional ships of less than 300 tons. As for the main communication function, in addition to the communications of radiotelephone with the handset and the Morse communication with the CW keyer, calling by digital selective calling (DSC) for a general or distress communication are possible. Furthermore, if the data terminal is connected to the controller, the telex communication in the ARQ or FEC mode using the NBDP is available. 1.2 Features ● Compliant with the ITU Radio Regulations (RR), the IMO performance standards, and the ITU-R recommendations. ● Contains all channels specified in the ITU Radio Regulations (RR). ● The separately designed controller and main unit enable easy installation in limited or difficult spaces. ● A semi-transmissive LCD with a wide viewing angle is easily viewable even in direct light or when backlit and allows it to be installed in a variety of positions. ● The backlights of the LCD and operation keys are fully adjustable, preventing interference with night watch keeping. ● When in distress, the DSC can send a distress message with the expanded position data accurate up to 1/10000 of a minute for both latitude and longitude to make search and rescue operations by the RCC easier. ● High-quality stable operation is possible by using DSP technology on a transceiver with a DSC/WKR modem. ● The DSC operates in Class A mode suitable for all areas, and in Class B mode limited to ships navigating in A1 and A2 areas. ● An advanced digital audio amplifier with a built-in loud speaker provides a maximum of 5 W of clear audio. ● The maintenance and the check can be easily done at daily or the regular services, because a special function key was prepared for the DSC safety test calling and the self-diagnosis. ● It is possible to operate on the screen with the character color and the background color corresponding to the favor because the data terminal for the telex communication by NBDP adopted the color liquid crystal display of the wide viewing angle in high brightness. ● Besides printers and GPS, other peripherals such as the remote maintenance system (RMS) can be connected to the equipment.

Operation 4-1 4. OPERATION This chapter describes basic operations of the controller and the data terminal, radiotelephone communications, telex communications, DSC calling procedures, and other radio functions. 4.1 Operation overview 4.1.1 Operation of the controller Basically, the controller is operated with the numeric keypad (10key), the MENU key, and the jog dial for other than the telex communication. The following is an overview of their operation. z When two controllers are connected, only one controller having the access right can operate the equipment except for sending a distress alert, changing audio volume, and changing display conditions. (Unless otherwise mentioned, the instructions below are for the controller with the access rights.) z To obtain the access right at a controller without access rights, press ENT to get the access right unless the other controller is being operated (PTT/KEY ON or menu operations). z The DISTRESS key is always available. (The DISTRESS key has the highest priority.) z On the status display or the operating display, the communication frequency or channel can be set by using the number keys or if the transceiver setting screen is focused on, setting it by rotating the jog dial is also available. z Pressing the TEL DSC or CW key changes the communication mode. If the screen displays in the menu, immediately shows the status display or the operating display, and also the channel input mode changes to the free frequency mode. Additionally, the communication mode can be changed to the AM mode to listen to the radio broadcasting or to the DATA mode to communicate using the intership fax z When the communication mode is set to TEL or CW, pressing the same communication mode key turns the PA on and off. (When the PA is on, ON mark appears.) z All functions can be accessed using the MENU key, jog dial, and the dedicated keys/controls. (See the menu tree on the next page.) Further, screens in the menu tree indicated by "Printable" can be printed from a printer connected to the controller or the data terminal by pressing and holding the FUNC key and then pressing the 7PRN key. z Pressing or pressing and holding the FUNC (function) key and a number key allows rapid access to that function. z There are two ways to access main menu items. After pressing the MENU key to display the main menu, use either the jog dial to move the cursor to the desired item and press ENT to select it, or select the item by pressing the respective number key. (Ex: For Self diagnosis (6.1.1 Transceiver), press MENUÎ6SPÎ1CLARÎ1CLAR) z Any menu can be assigned to the USER key to open it with a single touch of a button. z Normally the key is always enabled. z Pressing the CH key changes the channel input mode to the User ch, ITU ch or to the free frequency. This key is enabled when showing the status display or the operating display. z Pressing the CANCEL key in any menu moves the display up one level in the hierarchy (or to the status display). The same results can be achieved by selecting "0. Back" when available on-screen. Further, pressing the CANCEL key on an input line will clear the entered data. z Pressing the MENU key in any menu opens the main menu. Also, pressing MENU while in the main menu returns to the status display or the operating display. z Dialog boxes (popup screens) are opened when necessary and operations can be done in the dialog box. z When using DSC calls, to distinguish the messages or conditions, some specific alarms are provided as listed after the menu tree below.

Operation 4-4 4.1.2 Operation of the data terminal Basically, the every function concerning the telex mode such as ARQ/FEC communication or scanning can be operated from the data terminal. ● To connect and install the data terminal, setup the 7.6 Option menu of the controller. ● To set the communicate mode to the telex mode, press the Enter key of the keyboard. Additionally, that operation acquires the access right if the controller connected to that data terminal does not have the access right. ● Every function of the data terminal can be operated from the main menu displayed on a regular screen, excluding the screen of communication modes other than the telex, telex communicating screen, the telex file editing screen. ● Because the short-cut key to the table of next page is allocated in each item of the main menu or the drop down menu, it is possible to execute it easily according to few procedures. ● The guide of the item shown with the cursor is basically displayed under the screen in the data terminal. ● While displaying the menu screen on the controller, the data terminal cannot be operated temporally. Similarly, the controller cannot be operated during the telex communication except the operations of TEL DSC CW and DISTRESS keys. ● Besides the telex communication in ARQ/FEC mode, the data terminal has other functions such as editing telex messages and the station list, setup of the radio condition, or setup of the display color of the screen. ● The communication using ARQ mode can be started with a specific radio station by inputting the selcal number (ID) and the work frequency. ● The communication using CFEC mode can be started as the broadcasting by inputting the work frequency. ● The communication using SFEC mode can be started as the broadcasting for limited receivers by inputting the selcal number (group ID) and work frequency. ● The telex communication channel can be set by specifying ARQ or FEC in the DSC message. In this case, the telex communication may be started without inputting 9 digits selcal number (ID) and work frequency because those have been already set by the DSC calling. ● Up to 20 stations can be registered in the station list. ● The self-diagnosis of the data terminal is executed from the controller as well as other units. ● The controller outputs the printing data from the printer connected to the data terminal. ● The condition of the data terminal such as the startup or the sleep is synchronized to the controller connected or the system. ● When the data terminal detects any error(s) concerning to the internal flash memory, the keyboard, the printer or the connected USB memory, immediately shows the popup screen and the Information is displayed on the bottom line on the screen until the error is fixed.

Appendix 11-23 11.5 Guide to MF/HF operation Be aware of the following points when using the MF/HF radio equipment. z Frequencies available for communication are always changing. z Not all frequency bandwidths can always be used for communication. z After sending the DSC test call to a coast station, you will not always receive the acknowledgement. 1. About the MF/HF radio equipment Although for ship MF/HF radio equipment the 1.6 MHz to 27.5 MHz frequencies are normally available, select an appropriate frequency from the frequencies assigned to your ship for communication. As noted below, the use of the appropriate frequency depends upon the radio wave propagation characteristics of the ionosphere. Therefore, not all frequency bands are available for communication even if the equipment is functioning properly. 2. Special characteristics of MF/HF radio wave propagation As shown in the figure to the right, the major MF/HF radio waves used for communications are terrestrial waves (path 1) and waves reflected from the ionosphere (paths 2 and 3). You can communicate using waves reflected from the ionosphere and the earth because the effective communication range of terrestrial waves is limited6. The available range of frequencies for communication depends upon the radio wave propagation characteristics of the ionosphere. They will also change dramatically depending on the position and distance from the station, the season, the time, and the sunspot number (approx. 0 to 250) which changes every 11 years7. 3. Selecting communication frequencies MF/HF band communication frequencies cannot be predetermined. However, you can select frequencies referring to previous communications logs, the frequency transition table in this chapter under "Selecting communication frequencies in the MF/HF band (reference)", and the radio wave propagation image. 4. About DSC testing DSC operation is prescribed as an international standard8 of the ITU and coast stations that receive DSC test calls should acknowledge the calls. Responses may be sent manually instead of automatically depending on the equipment at the coast station. It may take longer than expected to receive the acknowledgement even if your equipment is functioning properly and you have selected the proper frequency. 6 You may experience skip zones where both terrestrial waves and waves reflected from the ionosphere are unavailable at the end of the effective communication range of terrestrial waves. 7 Radio wave propagation is affected by phasing, the Dellinger phenomenon, magnetic storms, and atmospherics. Interference tends to be greater at night when radio waves can travel greater distances. 8 ITU-R Recommendation M. 541 無線局 A23無線局 B1電離層　 F1/F2層電離層　 E層電離層　 D層地表Ionosphere F1/F2 layerIonosphere E layerIonosphere D layerStation AEarth Station B

Appendix 11-24 Selecting communication frequencies in the MF/HF band (reference) When communicating with the MF/HF radio equipment, select frequencies referring to the frequency transition table and the radio wave propagation images (excluding the polar latitudes) shown below9. Example: When communicating with a station approximately 5000 km away at around 12 pm in the winter with a sunspot number of 100, select frequencies in the 18, 22, or 25 MHz bands for the best results. ¾ Frequency transition table 日中夜間冬夏冬夏遠距離（例：5000km）近距離（例：1000km）距離季節と時刻 2M 4M 6M 8M 12M 16M 18M 22M 25M周波数選択の目安（太陽の黒点数 = 100の場合）通信条件日中夜間日中夜間日中夜間Transmissions conditions Distance Season & time Day Winter Night Day Long distances (e.g. 5000 km) Summer Night Day Winter Night Day Short distances (e.g. 1000 km) Summer Night Guideline for selecting frequency (for a sunspot count of 100) ¾ Radio wave propagation images 9 These are based on the prediction of HF radio wave propagations.
