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.

Equipment Overview

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 international passenger
ships and freight ships of 300 tons or more, but also conventional ships of less than 300 tons.
It has the DSC routine and distress call functions, and function keys that can be set to run a
self-diagnostic function and DSC safety test call for periodic inspections.

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).

● Separately designed transceiver and controller 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/WKR modem 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.

● A dedicated self-diagnosis key makes maintenance and inspection simple.

● Besides printers and GPS, other peripherals such as the remote maintenance system (RMS) can

be connected to the equipment.

Operation

4. OPERATION

This chapter describes basic controller operations, radiotelephone communications, DSC
calling procedures, and other radio functions.

4.1 Controller operation overview

Basically, the controller is operated with the numeric keypad (10key), the MENU key, and jog
dial. The following is an overview of their operation.

z When two controllers are connected, only one controller having the access right can operate

the radiotelephone, except for sending a distress call, 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 even if the controller does not have the access

right. (The DISTRESS key has the highest priority.)

z On the status display, the communication frequency or channel can be set by using the

number keys or by rotating the jog dial.

z Pressing the TEL , DSC , or CW keys changes the communication mode and returns

the menu display to the status display. When this is done, the channel input mode changes
to the free frequency mode.

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, TXON appears.)

z All functions can be accessed using the MENU key, jog dial, and the dedicated

keys/controls. (See the menu tree of the equipment on the next page.)

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 MENU Î 6SP Î 1CLAR Î 1CLAR )

Operation

4.5.3 Distress calls

When in distress, distress calls are always transmitted by pressing the dedicated DISTRESS

key. The distress calls transmit your own MMSI, ships position, time of the position, and the

nature of distress.

CAUTION

Do not test the distress call.
Doing so may inconvenience local shipping and rescue centers.

When sending a distress call, follow the instructions of the ship's captain or
officer in charge.

If a false distress call is transmitted accidentally, follow the instructions
below:

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, 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.

44..55..33..11

The following describes the procedure to send a distress call immediately without using menus.
In this case, the nature of distress in the message will be sent as "Undesignated" by default.
Further, if no information for the position and the time of position obtained within 23.5 hours, this
information will be composed automatically.

4.5.4 Distress relay calls on behalf of someone else

If another ship is in distress but is itself unable to make a distress call, and the master of the ship
considers that further help is necessary, the distress relay call on behalf of the ship can be
transmitted using the "DSC drobose call" menu. In this case, compose a distress relay call format
by inputting the MMSI (if known), the ship's position and the time of position (if known), and the
nature of distress to send to a specific area or a coast station.

CAUTION

When sending a drobose call, do NOT press the DISTRESS key. Doing so
may cause a false distress call.
(Drobose calls can be sent via the [Call] button displayed on the screen.)
