PRECAUTIONS BEFORE OPERATION
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
ii
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.
1Do not touch the victim confusedly as a result of the accident, but the rescuer
may also get an electric shock.
2Turn off the power source calmly and move the victim away quietly from the
electric line.
3Call a physician or ambulance immediately or ask someone to call a doctor.
4Lay the victim on this back and loosen his necktie, clothes, belt, etc.
5a. 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.
6Open 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.)
7Then, wipe his mouth so that foaming mucus does not accumulate inside.
FIRST-AID TREATMENTS
iii
When pulse is beating but breathing has stopped
(Mouth-to-mouth respiration) Fig. 1
1Tilt the victim's head back as far as this face looks back. (A pillow may be
inserted his neck.)
2Push his jaw upward to open his throat wide (to spread his airway).
3Pinch 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).
4Carefully watch that he has recovered his natural breathing and atop
practicing artificial respiration.
5If 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.
6When 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.)
z 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.ձ
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ղ
Or, pinch his nostrils with your fingers to
prevent air from leaking.ճ
(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
iv
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.
1Place 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)
2In 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)
3Examine 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.

DANGER
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.
Make sure to turn on the antenna operation switch.
Failure to comply may result in injuries caused by physical contact
with the rotating antenna.
PRECAUTIONS
viii
WARNING
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.
Do not get close to the radiant section of the antenna. It is a
rotating part, and it may cause injuries if it suddenly starts rotating
and consequently hits the body.
It is recommended that the radiant section be installed at a high
place such as on the roof of the wheelhouse, on the flying bridge,
on the trestle, or on the radar mast so that no one can get close to
it. When any work must be done on the antenna, make sure to turn
the antenna switch off.
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).
50W/m210W/m22.5W/m2
NKE-2103 n/a 26cm 123cm
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.
Do not touch the radiator. Even if the power is turned off, the
radiator may be rotated by the wind.
PRECAUTIONS
ix
CAUTION
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.
When using the sea clutter suppression function, never set the
suppression level too high canceling out all image noises from the
rain or snow at close range. Detection of not only echoes from the
rain or snow 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.
PRECAUTIONS
x
CAUTION
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.
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.
PRECAUTIONS
xi
CAUTION
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.
Make sure that two or more staff member work together when
replacing the LCD.
If only one person attempts to replace the LCD, he/she may drop it
and become injured.
Do not directly touch the inverter circuit of the LCD display with a
bare hand since high voltage temporarily remains in the circuit
even after the main power is shut off.
Failure to comply may result in electrocution.
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.
