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) 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. Press the CANCEL key on the controller (when appropriate, follow
the commands on screen) and terminate the transmission of the
distress call.
2. Report the false distress call to a nearby RCC (Rescue Coordination
Center).
(In Japan, inform the nearest Japan Coast Guard.)
Information to be reported:
The date/time, location, and reason why the false distress call was
transmitted. Also report the ship's name, type, nationality, and ID
number as well as the unit model name and manufacture number/date,
if possible.
3. Report the false distress call to nearby ships using 2182.0 kHz or
another frequency for distress and safety purposes on the
radiotelephone.
4. If any acknowledgements to the distress call are received, inform the
ships of the false distress call.
Do not short the lines of the mini plug. Doing so may cause malfunction.
