  • Page 3 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.
  • Page 4 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.
  • Page 5 ☆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.
  • Page 6 ☆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).
