High voltages, ranging from several hundreds to tens of thousands of volts, are used in electronic
apparatus, such as radio and radar instruments. These voltages are totally harmless in most operations.
However, touching a component inside the unit is very dangerous. (Any person other than authorized
service engineers should not service, inspect, or adjust the unit.)
High voltages on the order of tens of thousand volts are most likely to cause instant deaths from
electrical shocks. At times, even voltages on the order of several hundred volts could lead to electrocution.
To defend against electrical shock hazards, don't put your hand into the inside of apparatus. When you put
in a hand unavoidably in case of urgent, it is strongly suggested to turn off the power switch and allow the
capacitors, etc. to discharge with a wire having its one end positively grounded to remove residual charges.
Before you put your hand into the inside of apparatus, make sure that internal parts are no longer charged.
Extra protection is ensured by wearing dry cotton gloves at this time. Another important precaution to
observe is to keep one hand in your pocket at a time, instead of using both hands at the same time.
It is also important to select a secure footing to work on, as the secondary effects of electrical shock
hazards can be more serious. In the event of electrical shocks, disinfect the burnt site completely and
obtain medical care immediately.
Precautions for Rescue of Victim of
Electric Shock
When a victim of electric shock is found, turn off the power source and ground the circuit immediately.
If this is impossible, move the victim away from the unit as quick as possible without touching him or her
with bare hands. He or she can safely be moved if an insulating material such as dry wood plate or cloth is
used.
Breathing may stop if current flows through the respiration center of brain due to electric shock. If the
electric shock is not large, breathing can be restored by artificial respiration. A victim of electric shock
looks pale and his or her pulse may become very weak or stop, resulting in unconsciousness and rigidity at
worst. It is necessary to perform first aid immediately.

Method of First-Aid Treatment
☆Precautions for First-Aid Treatments
Whenever a person is struck by an electrical shock, give the patient artificial respiration immediately on
the spot, unless it is absolutely necessary to move the patient for safety's sake. Once started, artificial
respiration should be continued rhythmically.
(1) Refrain from touching the patient carelessly as a result of the accident; the first-aider could suffer
from electrical shocks by himself or herself.
(2) Turn off the power calmly and certainly, and move the patient apart from the cable gently.
(3) Call or send for a physician or ambulance immediately, or ask someone to call doctor.
(4) Lay the patient on the back, loosening the necktie, clothes, belts and so on.
(5) (a) Feel the patient's pulse.
(b) Check the heartbeat by bringing your ear close to the patient's heart.
(c) Check for respiration by bringing your face or the back of your hand to the patient's face.
(d) Check the size of patient's pupils.
(6) Opening the patient's mouth, remove artificial teeth, cigarettes, chewing gum, etc. if any. With the
patient's mouth open, stretch the tongue and insert a towel or the like into the mouth to prevent the
tongue from being withdrawn into the throat. (If the patient clenches the teeth so tight that the mouth
won't open, use a screwdriver or the like to force the mouth open and then insert a towel or the like
into the mouth.)
(7) Wipe off the mouth to prevent foaming mucus and saliva from accumulating.
(1) Bend the patient's face backward until it is directed to look back. (A pillow may be placed under
the neck.)
(2) Pull up the lower jaw to open up the airway. (to spread the airway)
(3) Pinching the patient's nose, breathe deeply and blow your breath into the patient's mouth strongly,
with care to close it completely. Then, move your mouth away and take a deep breath, and blow
into his or her mouth. Repeat blowing at 10 to 15 times a minute (always with the patient's nostrils
closed).
(4) Continue artificial respiration until natural respiration is restored.
(5) If the patient's mouth won't open easily, insert a pipe, such as one made of rubber or vinyl, into
either nostril. Then, take a deep breath and blow into the nostril through the pipe, with the other
nostril and the mouth completely closed.
(6) The patient may stand up abruptly upon recovering consciousness. Keep the patient lying calmly,
giving him or her coffee, tea or any other hot drink (but not alcoholic drink) to keep him or her
warm.
Mouth-to-mouth artificial respiration with the patient's head lifted
①

③
(1) Lift the back part of the patient's head.
Support the forehead with one of your
hand and the neck with the other hand.
→①.
Many patients will have their airways
opened by lifting their head in this way
to ease mouth-to-mouth artificial
respiration.
(2) Closing the patient's mouth with your
mouth, press your cheek against the
patient's nose→②.
Alternatively, hold the patient's nose
with your finger to prevent air leak →③.
(3) Blowing air into the patient's lungs. Blow
air into the patient's lungs until chest is
seen to rise. The first 10 breaths must be
blown as fast as possible.

Treatment to Give When the Patient Has No Pulse
Beating and Has Ceased to Breathe
*Performing cardiac massage - Fig. 2
If the patient has no pulse beating, with the pupils open and no heartbeat being heard, the patient has
a cardiac arrest and requires immediate artificial respiration. Continue this until a medical specialist
arrives, and follow his or her directions after that.
(1) Putting one hand on about the lower one third of the patient's ribs and the other hand over the
back of the first, with your elbow fully stretched (with bended elbow, you can’t press to the extent
the patient’s ribs are depressed), apply your body weight to the hands to press the patient's body
until it is depressed about 2 cm (Repeat this about 50 times a minute). (Cardiac massage.)
(2) If only one first-aider is available, perform a cardiac massage about 15 times and then give
mouth-to-mouth artificial respiration 2 times. Repeat this sequence. If two first-aiders are
available, while one person performs a cardiac massage 15 times, and the other should give
mouth-to-mouth artificial respiration 2 times. Repeat this sequence (combined cardiac massage
and mouth-to-mouth artificial respiration method).
(3) Check the patient's pupils and feel the pulse from time to time. When the pupils are restored to
normal and the pulse begins to beat regularly, stop treating and keep the patient calm while giving
him or her coffee, tea or any other hot drink to keep him or her warm while watching him or her
carefully.

cause electric shock. For maintenace, inspection, or adjustment of
equipment components, consult with our branch office, branch shop,
sales office, or our distributor in your district.
To contact our sales department, branch offices, branch shops, and
sales offecs:
Prese refer to the “Office List” at the end of the document.
Do not get close to the radiant section of the scanner. 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 bride, 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 scanner, make
sure to turn the safery switch off.
Microwave rediation level:
Keep out from a distance closer than that specified below for each
type of scanner when it is transmitting. Being within the specified
distance from the center of the front face of the scanner may cause
imicrowave exposure which could result in injuries (especially of the
eyes).
Make sure to install the scanner at a place higher than human height.
Direct exposure to electromagnetic wave at close range will have
adverse effects on the human body.
When it is necessary to get close to the scanner 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.

WARNING
When conducting maintenance work, make sure to turn off the power
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 may
result in electric shock, equipment failure, or accidents.
When cleaning the display screen, do not wipe it too strongly with a
dry coth. Also, do not use gasoline or thinner to clean the screen.
Failure will result in damage to the scrren surface.
Do not change MBS Level/Area unless absolutely necessary.
Incorrect adjustment will result in deletion of nearby target images and
thus collisions may occur resulting in death or serious injuries.
When disposing of used lithium batteries, be sure to insulate the
batteries by attaching a piece of adhesive tape on the
+ and ○-
○
terminals. Failure may cause heat generation, explosion, or fire when
the batteries get shorted out.

Page 13
CAUTION
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 Target Tracking (TT) function 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 tracking target
information may cause accidents.
Tracking target 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.
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.
When using the [AUTO SEA] 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 [AUTO SEA] function, make sure to choose the most
appropriate image noise suppression level.
When using the [AUTO RAIN] 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 [AUTO RAIN] function, make sure to choose the most
appropriate image noise suppression level.
- VII -
Page 14
CAUTION
When setting a guard 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 guard zone alarm will not be activated for targets
undetected by the radar, and it may result in accidents such as
collisions.
The simulation function is used exclusively for deciding whether or not
target tracking is properly operating. Therefore, never use this function
unless you wish to check target tracking operations.
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.
Optimal values have been set for VD LEVEL and CONSTANT; therefore,
never change their values unless absolutely necessary. Failure may
result in accidents that would lower target tracking performance.
Make sure to shut off the main power before replacing parts. Failure
may result in electric shock 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 may result in electrocution.
Make sure to take off your watch when your hand must get close to the
magnetron.
Failure 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.
- VIII -
Page 15
CAUTION
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 may result in electric shock.
Any adjustments must be made by specialized service personnel.
Incorrect settings may result in unstable operation.
Do not make any adjustments during navigation. Failure 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 may result in accidents or equipment failure.
Do not change the quantization level settings unless absolutely
necessary. If set at an inappropriate value, the target acquisition or
target tracking function deteriorates, and this may lead to accidents.
Do not do the backup operation of data while sailing.
The radar application is ended so that the data backup may begin. It
becomes impossible to do the observation using radar and this may
lead to accidents.
