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.
Cautions concerning treatment of
electrocution victims
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.

2
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 dentifrice, food 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 their 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.

3
☆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) Raise the back of the head, then place one
hand on the forehead and place the other
hand under the neck. →q
Most victims open their mouth when doing this,
making "mouth to mouth" resuscitation easier.
(2) Cover the victim's mouth by opening your
mouth widely, then push your cheek against
the victim's nose, →w
or pinch the victim's nose to prevent air from
leaking out of it. →e
(3) Completely exhale into the lungs.
Exhale into the lungs until the chest is inflates.
You have to blow as rapidly as possible for the
first 10 times.

w
e
("Mouth to mouth " artificial respiration) Figure 1.

4
☆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.

WARNING
Receiving a Distress Call
When a distress call is received, the DISTRESS & URGENCY LED lights up and alarm sounds. Up to 20
received distress calls are automatically stored in the memory for future reference. When a printer is
connected, the distress call is automatically printed out.
When a distress call is received, be sure to inform the ship’s captain or officer in
charge.
This affects the life of the crew and passengers on the ship in distress.
TIP
•A distress call has priority over all other operations.
•The distress message is first transmitted 5 times consecutively, followed by random intervals of 3.5 to
4.5 minutes thereafter. This process is repeated until a response is received.
•When a navigation system is connected, position and time data from the system is automatically
added to the distress massage.
•When no navigation aid is connected, the position and time data is transmitted as dummy data.
•When a printer is connected, the distress message is automatically printed out.
•Standby reception is carried out on CH16 during 3.5 min. to 4.5 min. pause between distress calls.
The DSC CH70 answer is received on the DSC Watchkeeping Receiver.
