iv
When conducting maintenance work, make sure to turn off the power and unplug
the power line of the processor 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.
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.
Ask the nearest branch, business office or a dealer for inspection and repair.
Turn off the main power before maintenance work. Otherwise, an electric shock
may result.
Turn off the main power before cleaning the equipment. Especially, make sure to
turn off the indicator if a rectifier is used. Otherwise, equipment failure, or death
or serious injury due to electric shock may result, because voltage is outputted
from the rectifier even when the radar is not operating.

Otherwise, heat generation, explosion or a fire may occur.

vi
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.
Normally, use the automatic tune mode.
Use the manual tune mode only when best tuning is not possible in the automatic
tune mode due to deterioration of magnetron.
If the gain is too high, unnecessary signals including receiver noise and false
video increase resulting in reduction of visibility of targets.
On the contrary, if the gain is too low, targets including ships and dangerous
objects may not be clearly indicated.
When using the [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 [SEA] function, make sure to choose the most appropriate image
noise suppression level.
When using the [RAIN] function, never set the suppression level too high
canceling out all image noises from the rain or snow at the 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 [RAIN] function, make sure to choose the most appropriate
image noise suppression level.
The accuracy from the vectors are depending on the accuracy from the (D)GPS
sensors. With longer vectors, the accuracy will be lower. The vectors are
calculated with the situation at that time. When there will be some changed
influence from wind, water current etc., are not shown before the vessel is
influenced by this.
Do not turn the system off while the display shows “Copying” in a message area
on the bottom center of the screen in order not to make a flash memory card
damaged.
Do not put watches, clocks, or magnetic cards close to the modulator unit since
this unit holds magnetrons having strong magnetic force. Failure or data
destruction of the above devices may result.
Turn off the main power source before replacing parts.
Otherwise, an electric shock or trouble may be caused.
Before replacing the magnetron, turn off the main power source and wait for 5
minutes or more until the high voltage circuits are discharged.
Otherwise, an electric shock may be caused.

vii
Take off your wrist watch when bringing your hands close to the magnetron.
Otherwise, your watch may be damaged because the magnetron is a strong
magnet.
Two or more persons shall replace the liquid crystal monitor.
If only one person does this work, he may drop the LCD, resulting in injury.
Even after the main power source is turned off, some high voltages remain for a
while.
Do not contact the inverter circuit in the LCD with bare hands.

zSafety Cautions z
Cautions for High Voltage
High voltages, ranging from several hundreds to tens of thousands 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 maintain,
inspect, or adjust the unit.)
High voltages on the order of tens of thousands 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.

ix
zEmergency Measures z
Method of First-Aid Treatment
Precautions for First-Aid Treatments
Apply artificial respiration to the person who collapsed, minimising moving as much as
possible avoiding risks. Once started, artificial respiration should be continued
rhythmically.
(1) Refrain from touching the patient carelessly as a resultof 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.


x
Treatment to Give When the Patient Has a
Pulse Beating but Has Ceased to Breathe
Performing mouth-to-mouth artificial respiration
(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] (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.o[1].
Many patients will have their airways
opened by lifting their head in this
way to ease mouth-to-mouth
artificial respiration.
[2]
(2) Closing the patient's mouth with your
mouth, press your cheek against the
patient's noseo[2].
Alternatively, hold the patient's nose
with your finger to prevent air leak
o[3].
[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.
