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 SOLAS Convention
ships such as international passenger ships and freight ships of 300 tons or more, but also
non-conventional ships of less than 300 tons.
As for the main communication function, in addition to the communications of radiotelephone with the
handset and the Morse communication with the CW keyer, calling by digital selective calling (DSC) for
a general or distress communication are possible. Furthermore, if the data terminal is connected to the
controller, the telex communication in the ARQ or FEC mode using the NBDP is available.

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).

● The separately designed controller and main unit 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 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.

● The maintenance and the check can be easily done at daily or the regular services, because a

special function key was prepared for the DSC safety test calling and the self-diagnosis.

● It is possible to operate on the screen with the character color and the background color

corresponding to the favor because the data terminal for the telex communication by NBDP
adopted the color liquid crystal display of the wide viewing angle in high brightness.

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

be connected to the equipment.

4. OPERATION

This chapter describes basic operations of the controller and the data terminal,
radiotelephone communications, telex communications, DSC calling procedures, and
other radio functions.

4.1 Operation overview

4.1.1 Operation of the controller

Basically, the controller is operated for other than the telex communication 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, channel input modes changes to
the free frequency mode. Additionally, setting to the AM mode to listen to the radiobroadcast,
or to the DATA mode to communicate with another ship using the intership fax are available.

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 on the next page.) Additionally, screens indicated by
"Printable" in the menu tree can be printed from a printer connected to the controller or the
data terminal by pressing and holding the FUNC key and then pressing the 7PRN key.

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 )

z Any menu can be assigned to the USER key to quickly open it with a single touch of a

button.

z Normally the key is always enabled.

z The CH key's channel input mode can be changed to a User channel, ITU channel, or to a

free frequency. This key is only enabled when the status display is displayed.

z Pressing the CANCEL key in any menu moves the display up one level in the hierarchy

(or to the status display). The same results can be achieved by selecting "0. Back" when
available on-screen. Further, pressing the CANCEL key on an input line will clear the
entered data.

z Pressing the MENU key in any menu opens the main menu. Also, pressing MENU

while in the main menu returns to the status display.

z If no operations are done for 10 minutes while a menu is open, the screen automatically

returns to the status display.

z Dialog boxes (popup screens) are opened when necessary and operations can be done in

the dialog box.

4.1.2 Operation of the data terminal

Basically, the every function concerning the telex mode such as ARQ/FEC communication or

scanning can be operated from the data terminal.

● To connect and install the data terminal, setup the 7.6 Option menu of the controller.

● To set the communicate mode to the telex mode, press the Enter key of the keyboard.

Additionally, that operation acquires the access right if the controller connected to that data
terminal does not have the access right.

● Every function of the data terminal can be operated from the main menu displayed on a

regular screen, excluding the screen of communication modes other than the telex, telex
communicating screen, the telex file editing screen.

● Because the short-cut key to the table of next page is allocated in each item of the main

menu or the drop down menu, it is possible to execute it easily according to few procedures.

● The guide of the item shown with the cursor is basically displayed under the screen in the

data terminal.

● While displaying the menu screen on the controller, the data terminal cannot be operated

temporally. Similarly, the controller cannot be operated during the telex communication
except the operations of TEL DSC CW and DISTRESS keys.

● Besides the telex communication in ARQ/FEC mode, the data terminal has other functions

such as editing telex messages and the station list, setup of the radio condition, or setup of
the display color of the screen.

● The communication using ARQ mode can be started with a specific radio station by inputting

the selcal number (ID) and the work frequency.

● The communication using CFEC mode can be started as the broadcasting by inputting the

work frequency.

● The communication using SFEC mode can be started as the broadcasting for a selected

group by inputting the selcal number (group ID) and work frequency.

● The telex communication channel can be set by specifying ARQ or FEC in the DSC message.

In this case, the telex communication may be started without inputting 9 digits selcal number
(ID) and work frequency because those have been already set by the DSC calling.

● Up to 20 stations can be registered in the station list.

● The self-diagnosis of the data terminal is executed from the controller as well as other units.

● The controller outputs the printing data from the printer connected to the data terminal.

● The condition of the data terminal such as the startup or the sleep is synchronized to the

controller connected or the system.

● When the data terminal detects any error(s) concerning to the internal flash memory, the

keyboard, the printer or the connected USB memory, immediately shows the popup screen
and the Information is displayed on the bottom line on the screen until the error is fixed.

When communicating in the telex mode, the data terminal is used. In the telex communication,

the ARQ (Automatic Repeat reQuest) mode and FEC (Forward Error Correction) mode are

available to communicate between two stations and to broadcast respectively. Additionally in the

FEC mode, there are two modes of the CFEC (Collective Forward Error Correction) mode for

unspecified receivers and SFEC (Selective Forward Error Correction) mode for specified

receivers, which are selectable according to the purpose.
