Cautions for high voltage

High voltages from hundreds volts to tens of thousands volts are to be applied to the
electronic equipment such radio and radar devices. You do not face any danger
during normal operation, but sufficient cares are required for maintenance, inspection
and adjustment of their internal components. (Maintenance, check-up and adjustment
of the inside of the equipment are prohibited except by maintenance specialists. ) High
voltages of tens of thousands volts are so dangerous as to bring a death from electric
shock, but even voltages of hundred volts may sometimes lead to a death from
electric shock. To prevent such an accident, make it a rule to turn off the power switch,
discharge capacitors with a wire surely earthed on an end make sure that internal
parts are no longer charged before you touch any parts inside these devices. At the
time, wearing dry cotton gloves ensures you further to prevent such danger. It is also a
necessary caution to put one of your hands in the pocket and not to use your both
hands at the same time.
It is also important to select a stable foothold always to prevent additional injuries
once you were shocked by electricity. If you were injured from electric shock, disinfect
the burn sufficiently and get it taken care of promptly.

■

What to do in case of electric shock

When finding a victim of electric shock, turn off the power source and earth the circuit
immediately. If it is impossible to turn off the circuit, move the victim away promptly
using insulators such as dry wood plate and cloth without touching the victim directly.
In case of electric shock, breathing may stop suddenly if current flows to the
respiration center in the brain. If the shock is not so strong, artificial respiration may
recover breathing. When shocked by electricity, the victim will come to look very bad
with weak pulse or without beating, resulting in unconsciousness and rigidity. In this
case, it is necessary to perform an emergency measure immediately.

FIRST-AID TREATMENTS

FIRST-AID TREATMENTS

■

First-aid treatments

As far as the victim of electric shock is not in dangerous condition, do not move him and
practice artificial respiration on him immediately. Once started, it should be continued
rhythmically.

1 Do not touch the victim confusedly as a result of the accident, but the rescuer may also

get an electric shock.

2 Turn off the power source calmly and move the victim away quietly from the electric

line.

3 Call a physician or ambulance immediately or ask someone to call a doctor.
4 Lay the victim on this back and loosen his necktie, clothes, belt, etc.
5 a. Examine the victim's pulse.

b. Examine his heartbeat bringing your ear close to his heart.
c. Examine his breathing bringing the back of your hand or your face close to his face.
d. Check the size of the pupils of his eyes.

6 Open the victim's mouth and take out artificial teeth, cigarette or chewing gum if any.

Keep his mouth open, stretch his tongue and insert a towel or the like in his mouth to
prevent the tongue from suffocating. (If it is hard to open his mouth due to set teeth,
open it with a screwdriver and insert a towel in this mouth. )

7 Then, wipe his mouth so that foaming mucus does not accumulate inside.

FIRST-AID TREATMENTS

■

When pulse is beating but breathing has stopped

(Mouth-to-mouth respiration) Fig. 1
1 Tilt the victim's head back as far as this face looks back. (A pillow may be

inserted his neck. )

2 Push his jaw upward to open his throat wide (to spread his airway).
3 Pinch the victim's nostrils and take a deep breath, block his mouth completely with

yours and blow into his mouth strongly. Take a deep breath

again and blow into his mouth.
Continue this 10 to 15 times a minutes (blocking his nostrils).

4 Carefully watch that he has recovered his natural breathing and atop

practicing artificial respiration.

5 If it is difficult to open the victim's mouth, insert a rubber or vinyl tube into one of his

nostrils and blow into it blocking the other nostril and his mouth completely.

6 When the victim recovers consciousness, he may try to stand up suddenly, but let

him lie calmly and serve him with a cup of hot coffee or tea and keep

him warm and quiet. (Never give him alcoholic drinks. )

●

Method of mouth-to-mouth respiration by raising head

Fig. 1 Mouth-to mouth respiration

(1) Raise the victim's head. Support his

forehead with one of your hand and his
neck with the other hand. →①
When you tilt his head backward, the
victim, in most cases, opens his mouth to
the air. This makes mouth-to mouth
respiration easy.

(2) Cover his mouth as widely as possible with

yours and press your cheek against
his nose→②
Or, pinch his nostrils with your fingers to
prevent air from leaking. →③

(3) Blow into his lungs. Continue blowing into

his mouth until his breast swells.
Blow into his mouth as quickly as
possible for the first 10 times.

FIRST-AID TREATMENTS

■

When both pulse and breathing have stopped

Perform the (Cardiac massage) Fig. 2 and (Mouth-to-mouth respiration) Fig. 1

When no pulse has come not to be felt, his pupils are open and no heartbeat is heard,
cardiac arrest is supposed to have occurred and artificial respiration must be
performed.

1 Place your both hands, one hand on the other, on the lower one third area of his

breastbone and compress his breast with your elbows applying your
weight on his breast so that it is dented about 2cm (Repeat compressing his breast

50 times or so a minutes). (Cardiac massage)

2 In case of one rescuer, Repeat cardiac massages about 15 times and blow into his

mouth 2 times quickly, and repeat this combination.

In case of two rescuers, one person repeats cardiac massages 15 times while the
other person blow into his mouth twice, and they shall repeat this combination.
(Perform the cardiac massage and mouth-to-mouth respiration)

3 Examine his pupils and his pulse sometimes. When the both have returned to

normal, stop the artificial respiration, serve him with a cup of hot coffee or

tea and keep him warm and calm while watching him carefully. (Never give him
alcoholic drinks. ) Commit the victim to a medical specialist depending on his
condition. To let him recover from the mental shock, it is necessary for persons
concerned to understand his situations and the necessary treatment.

PRECAUTINS

PRECAUTIONS

Never carry out internal inspection or repair work of the equipment
by users.
Inspection or repair work by unauthorized personnel may result in
fire hazard or electric shock.
For inspection and repair work of equipment components, consult
with our branch office, branch shop, sales office, or our distributor
in your district.

When conducting maintenance, make sure to turn the main power off.
Failure to comply may result in electrocution.

Turn off the main power before cleaning the equipment. Especially
when a rectifier is used, make sure to turn it off since voltage is
still output from the rectifier even after the radar is turned off.
Failure to comply may result in equipment failure, electric shock or
serious injury.

When conducting maintenance work on the antenna, make sure to
turn its main power off.
Failure to comply may result in electrocution or injuries.

DANGER

PRECAUTINS

Never directly touch the internal components of the antenna,

receiver/transceiver, or indicator.
Direct contact with these high-voltage components may cause
electrocution. For maintenance, inspection, or adjustment of
equipment components, consult with our branch office, branch
shop, sales office, or our distributor in your district.

Microwave radiation level:
Keep away from a scanner when it is transmitting.
The high level of microwave is radiated from the front face of the
scanner specified below. The microwave exposure at close range
could result in injuries (especially of the eyes).

Make sure to install the antenna at a place higher than human
height.

Direct exposure to electromagnetic waves at close range will have
adverse effects on the human body.
Direct exposure to electromagnetic waves at close range will have
adverse effects on the human body. When it is necessary to get
close to the antenna for maintenance or inspection purposes,
make sure to turn the indicator power switch to "OFF" or "STBY."
Direct exposure to electromagnetic waves at close range will have
adverse effects on the human body.
When conducting maintenance work, make sure to turn off the
power and unplug the power connector J1 of the display unit so
that the power supply to the equipment is completely cut off.
Some equipment components can carry electrical current even
after the power switch is turned off, and conducting maintenance
work without unplugging the power connector may result in
electrocution, equipment failure, or accidents.

WARNING

PRECAUTINS

A malfunction may occur if the power in the ship is

instantaneously interrupted during operation of the radar. In this

case, the power should be turned on again.

Always use the automatic tuning mode.

Use the manual tuning mode only when the automatic tuning

mode does not provide the best tuning state due to deterioration

of magnetron for example.

If sensitivity is set too high, unnecessary signals such as noises in
the receiver and false echoes increase to lower target visibility.
At the same time, if sensitivity is set too low, detection of targets
such as ships and dangerous objects may be hindered.
Therefore, sensitivity must always be set to an optimal level.

When using the sea clutter suppression function, never set the suppression

level too high canceling out all image noises from the sea surface at close

range. Detection of not only echoes from waves but also targets such as other

ships or dangerous objects will become inhibited.

When using the sea clutter suppression function, make sure to choose the

most appropriate image noise suppression level.

Use the radar only as a navigation aid.

The final navigation decision must always be made by the operator him/herself.

Making the final navigation decision based only on the radar display may

cause accidents such as collisions or running aground.

Use the target tracking function (TT) only as a navigation aid. The final

navigation decision must always be made by the operator him/herself.

Making the final navigation decision based only on the target tracking function

(TT) information may cause accidents.

The target tracking function (TT) information such as vector, target numerical

data, and alarms may contain some errors. Also, targets that are not detected

by the radar cannot be acquired or tracked.
Making the final navigation decision based only on the radar display may cause
accidents such as collisions or running aground.

CAUTION

PRECAUTINS

Target Tracking Function Test is provided to test if the target

tracking function is operating normally. Thus, do not use the

function except when you test the target tracking function.

Note especially that, if this function is used during actual

navigation, simulated targets are displayed and may become

confused with other actual targets. Therefore, never use this
function during actual navigation.

When a large value is set as an association condition, a tracked

target near an AIS target is identified as the AIS target and may

thus disappear from the display.

For example, when a pilot vessel equipped with the AIS function (a

small target which is not a tracked target) goes near a cargo vessel

which is a tracked target without the AIS function, the tracked
target symbol for the cargo vessel may disappear.

Since these alarms may include some errors depending on the

target tracking conditions, the navigation officer himself should

make the final decision for ship operations such as collision avoidance.

Making the final navigation decision based only on the alarm may
cause accidents such as collisions.

When setting an automatic acquisition zone, make sure to properly

adjust gain, sea-surface reflection suppression level, and

rain/snow reflection suppression level so that the optimal target

images are always on the radar screen. The automatic acquisition

zone alarm will not be activated for targets undetected by the
radar, and it may result in accidents such as collisions.
Any adjustments must be made by specialized service personnel.
Incorrect settings may result in unstable operation.

Do not make any adjustments during navigation. Failure to comply

may result in adverse effects on the radar function which may lead
to accidents or equipment failure.

Any adjustments must be made by specialized service personnel.

Failure to comply may result in accidents or equipment failure.

Make sure to shut off the main power before replacing parts.

Failure to comply may result in electrocution or equipment failure.

CAUTION

PRECAUTINS

When replacing magnetrons, make sure to shut off the main power

and let the equipment stand for more than 5 minutes to discharge

the high-voltage circuit.
Failure to comply may result in electrocution.
Make sure to take off your watch when your hand must get close
to the magnetron.
Failure to comply may result in damage to the watch since the
magnetron is a strong magnet.

When cleaning the display screen, do not wipe it too strongly with

a dry cloth. Also, do not use gasoline or thinner to clean the screen.
Failure to comply will result in damage to the screen surface.

1-3 INSTALLATION OF THE SCANNER UNIT

1-3-1 SELECTING THE INSTALLATION POSITION

■ PHYSICAL SELECTION CRITERIA

■ Install the scanner at the center of the mast on the keel line.

■ If the scanner cannot be installed at the above position for some reason, the amount of deviation

must be minimized. And, reinforce the mount base and the platform and take precautions to
protect the scanner from vibration and impact at the installation position.

■ There needs to be no influence of the dust by smoke from a chimney.

■ Please secure maintenance spaces (a platform, a safety link, a handrail, a step, etc.).

■

ELECTRICAL SELECTION CRITERIA

■ The installation height of the scanner relates to the maximum detection distance.
The higher, the better. However, if it is too high, radio wave energy greatly attenuates
above the scanner's vertical beam width (the point -3 dB from the peak of the main-lobe).
As a result, it is difficult to detect a close-in target. Sea clutter also increases.
Determine the installation height by taking into consideration the weight, maximum
length of the cable, and maintenance after installation. If the installation height of the
scanner is low, it is difficult to detect a long distance target. The ship's mast, derrick,
and chimney interfere with radiating beam causing the range that cannot be viewed
on the radar display to increase.
Generally, the lowest scanner installation position is supposed to be on the A-B line
shown in Fig. 1-3-2. In the case of the JMA-1030 type radar, 2θ equals 25°.
Specifically, the scanner position is normally elevated so that the chimney and the

shrine-gate type mast do not interfere with radiating beam.

Chapter 1 INSTALLATION

13

1-3-2 LOWEST SCANNER INSTALLATION HEIGHT

JMA-1030 : θ= 12.5 ° 2θ= 25 °

Fig. 1-3-2

■ If it is considered that sufficient installation height cannot be provided when the
scanner is installed directly on the roof of the wheelhouse, use a mounting rack or
radar mast (Fig. 2.1-3). Normally, when the scanner installation height is less than 2
meters from the roof of the wheelhouse, provide a mounting rack assembled at an
angle frame to install the scanner. When the scanner installation height is 2 m or
higher from the roof of the wheelhouse, provide a cylindrical radar mast to install the
scanner. Consider the convenience of the service staff who take care of installation,
maintenance, adjustment, and repair of the scanner by providing adequate footholds

to the mounting rack and the radar mast

1-3-3 MOUNTING RACK AND MAST FOR THE SCANNER

Fig. 1-3-3

■ When installing the scanner, select a location where there are the fewest structural

objects in the surrounding area so that false images which interfere with target
detection will not be generated by signal reflection from other scanners, deck
structures, and cargo. Only as a guide, note that structural objects should not exist

within the range of the vertical beam width (Fig. 1-3-4).

1-3-4 SCANNER AND THE SURROUNDING STRUCTURAL OBJECTS

Vertical beam width of X-band: Approx. 20° (+/-10.0° when the height of the radiating section is 0°).

Fig. 1-3-4

When installing two scanners, provide a height difference so that those two scanners do
not enter each other's vertical beam width range.
To avoid interference with other equipment and to prevent radio noise from generating,
do not place the VHF antenna, GPS antenna, and INMARSAT's dome within the range
of the vertical beam width. Keep a record of installation height data. The data is
necessary for the initial setting of the display unit.

■ Minimize the blind sector, and ensure the adequate view angle so that the blind
sector does not exist in the range 22.5° from side to rear (Fig. 1-3-5). Specifically,

ensure a sufficient view field in the straight front (relative bearing 000°).

Chapter 1 INSTALLATION

15

1-3-5 ENSURING VIEW ANGLE

Fig. 1-3-5

■ Magnetron which has strong magnetic force is included in the scanner. Install the
scanner at least 3 meters away from nautical instruments including magnetic
compasses and chronometers.

* If there is a concern that structural objects existing within the vertical beam width

may generate false images, equip the structural objects with a radio wave absorber.
(There are two types of absorbers: broadband type having no specific resonant
frequency and narrowband type which can absorb a band with a specific frequency.
Use those where applicable.) Furthermore, it is effective to install a metal reflector,
which reflects radio waves upwardly, between the scanner and a structural object so

that the radar's radio wave will not directly come in contact with the structural object

Reference:

■ Because most radio wave absorbers have poor durability, some must be replaced
every year.
When installing a reflector, the area to the rear of the reflector becomes a blind sector.
Therefore, minimize the size of the reflector.

■ The above procedures for selecting an scanner installation position are described
based on the radar's scanner. Comprehensively select the scanner position by
considering other scanners' installation procedure manual, hull's structure, strength of

the selected position, and vibration.

■

Confirmation during test run

If the scanner vibrates a lot during test run, try to reduce or prevent vibration by
reinforcing the scanner mount base or using wire stays attached to the radar mast.

Others

■ The design of the mounting platform for the scanner should take into account the
vibration requirements defined by IEC 60945.

13.2 Hz to 100 Hz

Amplitude

■ All installations should facilitate protection of equipment, including cabling, from
damage.

■ The cables should be kept as short as possible to minimize attenuation of the signal.

■ Crossing of cables should be done at right angles(90°) to minimize magnetic field

coupling.

■ Install the radar cable as far as from the cables of other radio equipment in order to
prevent other radio equipment from interfering with the radar operations. Especially
inter-wiring cables between scanner unit and display unit of the radar should not be
run parallel with the cables of other radio equipment.

■ Cable should not be exposed sharp bends.

■ Ensure that the equipment is grounded.

■Maintain a flat level surface on which to install the scanner.

■ Use sufficiently thick steel material and reinforcement material for the scanner's
installation surface (mount base) to reduce vibration and impact. Keep the mount
base flat and smooth.

■ If there is a partial gap between the mount base and the scanner chassis's legs, work
on the installation surface so that it becomes flat and smooth, or make adjustments
by inserting metal shims.
If a gap exists and the scanner is tightly clamped, the chassis will distort and become
damaged by vibration.

■

Avoid using vibration-proof rubber and resin

■ Do not insert an elastic body, such as vibration-proof rubber or resin, between the
mount base and the scanner chassis' legs. If rubber or resin is inserted, the amplitude
of vibration increases, resulting in the possibility of damage to the scanner.
Furthermore, if installation bolts become loose due to deterioration of rubber or resin,
the scanner may be damaged or fall from its mount

Bolts, nuts and tightening torque to be used

■ Use stainless steel bolts for the scanner and uniformly tighten all of the bolts using

double nuts for each bolt so that the scanner will not become loose (Table 1-2-1).

■ Although the length of the bolt will differ according to the thickness of the mount

base, use a bolt long enough so that more than 4 millimeters of thread protrudes
beyond the double nuts after the double nuts have been tightened.

Use of washer and corrosion-resistant measures

■ At the location where a bolt's head or nut comes in contact with the scanner chassis'

legs and the mount base, insert a plain washer which fits the bolt; and, at the location
where the nut comes in contact with the plain washer, insert a spring washer, and
then securely tighten the nuts .

■ To prevent corrosion due to the contacts between different metals, such as the

scanner chassis' legs, installation surface, bolts, nuts, etc., cover the bolt's head and
nuts with sealant .

■

Grounding and corrosion-resistant measures

■ Do not install the scanner in place where puddles are often formed.
