1、SERVICE SERVICE MANUALMANUAL 150W MF/HF RADIO EQUIPMENT150W MF/HF RADIO EQUIPMENT JSS-2150JSS-2150 . 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 no

2、rmal 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 v

3、olts. 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 electrici

4、ty 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 ne

5、cessary 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 ar

6、e 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 victims cond

7、ition 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 treatm

8、ent 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

9、 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). (

10、5) (a) Check the victims pulse. (b) Check for a heartbeat by pressing your ear against the victims chest. (c) Check if the victim is breathing by putting the back of your hand or face near the victims face. (d) Check the pupils of the eyes. (6) Open the victims mouth and remove any artificial teeth,

11、 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 victims 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

12、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 victims head facing backward (place something under the neck like a pillow). (2) Point the chin upward to widen the tra

13、chea. (3) Pinch the victims nose, take a deep breath, then put your mouth over the victims mouth and exhale completely, making sure that your mouth completely covers the victims mouth. Then remove your mouth. Repeat this routine 10 to 15 times per minute (holding the nostrils). (4) Pay attention to

14、the victim to notice if he or she starts to breath. If breathing returns, stop resuscitation. (5) If it is impossible to open the victims 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

15、, 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) Raise the back

16、of head, then place one hand on the forehead and place the other hand under the neck. Most victims open their mouth when this is done, making “mouth to mouth” resuscitation easier. (2) Cover the victims mouth by opening your mouth widely, then push your cheek against the victims nose, or pinch the v

17、ictims nose to prevent air from leaking out of it. (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 (H

18、eart 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

19、 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 tw

20、ice. 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 pup

21、ils 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 victims rec
