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.

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.

1. EQUIPMENT OVERVIEW

1.1 Functions

This equipment includes VHF radiotelephone, Class-A DSC and DSC watchkeeping 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 radiotelephone, the DSC communication functions, received voice recording and

playback function, and self-diagnosis function with simple operation using a dedicated key.

Additionally, it offers such as public address function using an external speaker, intercom function

for communication between controllers, and the DSC calling function using an automatic

identification system (AIS) information.

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).

● In addition to channels specified in the ITU Radio Regulations (RR), this equipment also

provides USA, Canada, European inland waterway, and weather channels. It also allows the

use of up to 200 private channels.

● Contains ATIS (Automatic Transmitter Identification System) function for the inland waterway

channels.

● Separately designed transceiver and controller enable easy installation in limited or difficult

spaces.

● A semi-transmissive LCD with a wide viewing angle features easily viewable even when with

straight light or backlit and allows it to install variety positions.

● The backlights of the LCD and operation keys are fully adjustable, preventing interference

with night watch keeping.

● The DSC is very easy to operate, especially a routine call, which can be sent by pressing the

dedicated routine call key and selecting address only. Additionally prepared a dedicated

menu for DSC safety test calling to make a radio communication inspection simple.

● When in distress, the DSC can send the distress message with the expanded position data

containing the digits up to 1/10000 of minutes for both latitude and longitude to make search

and rescue operation by the RCC easier.

● The received voice recording and playback function enables later confirmation or temporary

saving of communications.

● An advanced digital audio amplifier with a built-in loud speaker provides 5Wmax of clear audio.

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

● Besides printers and GPS, other peripherals such as the AIS, the VDR, and/or remote

maintenance systems (RMS) can be connected to this equipment.

4. OPERATION

This chapter describes basic controller operation, radiotelephone communication, DSC

calling procedures, and other radiotelephone 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.

● When two or more 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.)

● To obtain the access right at a controller without access rights, press the jog dial or take the

handset off-hook under such condition that the controller with the access rights is not in use (such

as taking a handset off-hook, pressing the PTT ON, or operating menu). However note that a

controller installed as a high priority can always obtain the access right if only at the PTT OFF

condition.

● The DISTRESS key is always available even if the controller does not have the access right.

(The DISTRESS key has the highest priority.)

● To verify a prepared DSC message just before sending, provides two types of verification screens:

Simple mode (shows editable information only) and Detail mode (shows every information).

● On the status display, the VHF channel number can be set by using the numeric keys directly or

by rotating the jog dial.

● On the status display, pressing the CANCEL key opens the squelch temporally to listen to the

receiving audio (or noise).

● Placing the handset back on-hook will return the channel to CH16 (factory default value). Also,

the on-hook detection can be disabled at the menu 9.3-5 Hook switch.

● 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.)

● Pressing the FUNC (function) key and a numeric key allows rapid access to that function.

● 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 numeric key.. (e.g. To select a menu for safety call

to all ships (2.1.1 All Ships), press MENU Æ 2SCAN Æ 1DW Æ 1DW .）

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

● 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.

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

while in the main menu returns to the status display.

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

the status display.

● Dialog boxes (pop-up screens) are opened when necessary and operations can be done in the

dialog box.

● Screens in the menu tree on the following page indicated by "Printable" can be printed from a

printer connected to the controller by pressing and holding the Func key and then pressing the

7PRN key.

・ When a coast station has transmitted an all ships or individual distress relay call.

・ When another ship station has transmitted a distress relay call to all ships, an individual

distress relay call, or a geographic distress relay call to a specific sea area.

As a general rule, the ship stations should respond via radiotelephony after receiving a distress relay

call. But if called individually by another ship station, and if allowed by a coast station, a distress

relay acknowledgement can be transmitted as follows. Further, a distress relay acknowledgement can

be composed from the log of the received distress relay message.

5.5 Advanced settings for DSC

The following describes the procedure for the advanced DSC settings such as automatic acknowledgement, as

well as creating a PSTN number list.

■ Menu screen ■

Press the MENU key, and through hierarchical

menus, select the 9.5 DSC operation.

The following describes the procedures from this screen.

Note that the screen at right shows factory default settings.

5.5.1 Automatic acknowledgement

If the automatic acknowledgement is set to ON, and when received any one of the individual calls below, the

acknowledgement will be sent automatically without notice.

・ Routine - a polling call

・ Safety - a position request call

・ Safety - a test call

This function will be disabled in distress mode or PSTN communication mode, or while the PTT is ON.

Furthermore, if performed this function during dual watch or scanning, the channel dwell time might be longer

than usual.

■ Procedure ■

To activate the automatic acknowledgement function, set the 1. Automatic ACK condition to ON

with the jog dial.

5.5.2 Disabling the automatic channel shift

When receiving any one of the following DSC calls having a valid working channel, the radiotelephone channel

can be shifted automatically to the specified channel. (Note : For the other DSC calls, the channel shift can be

performed manually.)

・ Routine - a group call

・ Safety - an All ship call

・ Routine/ Safety/ Urgency - an acknowledgement to the individual call own ship has transmitted before.

However, to avoid disruption of the important ongoing communication, this function must be disabled according to

the menu operation. The following describes the procedure to disable this function.

■ Procedure ■

To disable the automatic channel shift function, set the 2. Automatic CH shift condition to OFF

with the jog dial.

5.5.3 Disabling receiving alarms for routine and safety calls

The aural alarm for routine and safety calls can be disabled as follows.

■ Procedure■

To disable the receiving alarms for routine and safety calls, set the 3. Safety/Routine ALM

condition to OFF with the jog dial.

5.5.4 Medical/Neutral use setting for urgency calls

The following describes the procedure to set the condition so that an urgency all ships call containing the

additional subject of either "Medical transportation" or "Neutral nationality" can be sent.

Additionally, note that this setting will return to the default setting (OFF) if the power is turned off.

■ Procedure ■

To use these kinds of calls, set the 4. Medical/Neutral use condition to ON with the jog dial.

5.5.5 Expanded MMSI registration

If existing multiple DSC devices having the same 9-digit MMSI on board a ship, setting the 10th digit of the MMSI

number to a non-zero value is available to distinguish them in the case of routine individual calls.

The handling of 10-digit MMSI is as follows.

・ When sending a routine individual call, the caller ID (own ship station's MMSI) will be 10-digit MMSI.

・ When receiving a routine individual call, the DSC having the identical address only will treat the message, i.e.

mainly the DSC having "0" as the 10th digit of MMSI will receive an individual call addressed to the own

station.

・ When sending an acknowledgement to a received individual call, the address of the call will be entered the

caller's ID of the individual call as it is, i.e. if the 10th digit of the caller's ID is not "0", the address will be

10-digit MMSI automatically.

■ Procedure ■

To register the 10th digit of own MMSI, set the number to the 5. Expanded MMSI condition with

the numeric keypad or the jog dial.

CAUTION

Usually, it is not necessary to set it as any values other than zero.”0”.

Please be sure to set the VHF transceiver installed in a bridge as “0”

When values other than “0” are set up, DSC may be unable to receive.
