Cautions for High Voltage

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

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.

Electric Shock

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

gentl y.

(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.

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-aide 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-aides 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.

1.1 Function

The JRC JLN-650/652 is a Doppler Current Meter that transmits the supersonic wave from the transducer
equipped with the ship bottom to the sea bottom, measures information necessary for operation such as
a absolute tidal current, a relative tidal current, bottom tracking ship speed, and water tracking ship speed
from the signal reflected by the sea bottom or the plankton in the sea etc. , and displays it in high
resolution color LCD.

1.1.1 Function of This System

The JLN-650/652 displays a fish finder image in four direction: port ahead, starboard ahead, port astern
and starboard astern at the same time, besides information necessary for fishing operation like a
absolute tidal current, a relative tidal current, bottom tracking ship speed, and water tracking ship speed
is displayed at the same time. In addition, the water temperature graph and the wind direction speed of
the wind graph can be displayed from the input of the water temperature data and the wind direction
speed of the wind data from the outside.

The current screen displays at the same time for the ship course and the direction/speed of the current in
five layers that sets depth beforehand.
The depth setting of the each level can be set within the range of 2-500m(*1). As for the current display,
the speed display is switched to a numeric display and the echo graph display.

The ship speed screen displays the trip distance and the ship course except the numerical value display
and the graphical display, and it has the function as ship speed meter.

The shoal of fish screen displays the shoal of fish image in four directions on division into four, division
into two, and one screen. The JLN-650/652 displays the same image as a usual fish finder can be
displayed in sensitivity and the bubble cancellation with the knob.

The graph screen displays the change for the current direction and speed of the current in five layers, and
depth, ship speed, water temperature and wind speed in the graph.

The track plot screen displays the current speed of the current in five layers on the own track in the
vector.

The profile screen in real time displays the current in 100(JLN-650)/50(JLN-652) layers or less in the
graph. There are a line graph and an ellipse graph display in the profile screen, and in the ellipse graph
display, the flow speed of the current in 100(JLN-650)/50(JLN-652) layers is confirmed and can the twist

1.2 Features

Clear Image by a High Resolution

・An exact and vivid image is displayed by adopting the LCD indicator of the ultra-high-density 15

inches.
Important data was displayed by a big character, and made a screen to see easily more.

Easy Operation

・The key to the minimum requirement is arranged in the operation panel, and a usual operation can

be used only by pushing the change key to the screen.

・A usual setting can be done by comprehensible "Selection frame menu screen". Moreover, it is

possible to return to former set screen for one key operation after the setting ends with the menu
panel.

Function of Shoal of Fish Image in Four Directions

・This device can display the shoal of fish image in four directions of port ahead/astern and starboard

ahead/astern

done compared with the fish finder that searches only for the right under of the ship, the
movement of the shoal of fish and the judgment of the inclination of bottom of the sea etc. can be
facilitated.

in the direction of the prow at the same time. Because a wide-ranging search can be

Function of Graph Display of Current, Depth, Ship Speed,
Water Temperature, and Wind Speed

・The history situation can be displayed in the graph for 24 hours or less. The change in the current, depth,

ship speed, the water temperature, and the wind speed by the passage of time can be easily
confirmed. The data input from the water temperature meter and the wind direction/anemometer
separately is needed for the display of the water temperature and the wind speed.

・A detailed value on the graph can display the search with the cursor.

Function of Current and Track Plot Display

・The direction and the current speed of the current in five layers can be displayed on the own track. To

display the own track in latitude/longitude, the input of the positional data such as GPS is separately
needed.

・Either of the display colors of the own track of five layers can be displayed by the color corresponding to

reflection strength of one layer.

Function of Profile Display

・The current in 100(JLN-650)/50(JLN-652) layers or less is in real time displayed in the graph. In the

ellipse graph display, the current speed of the current in 100(JLN-650)/50(JLN-652) layers is
confirmed and can the twist and swinging of the current can visually be confirmed by displaying the
vector on the ellipse.

3.3.8 Simple Setting and Reference Value of Measurement Setting

The reference value of a measurement setting according to situation is introduced.

Note: By setting a reference value, it does not guarantee that a situation improves.

In the tidal current measurement mode (all screens except fish finder mode)
Filter setting using STC knob is possible.
Filter setting by the STC knob,
One-dimensional setting (-15 to 0 to +6) with the STC knob is enabled.
In the past, adjustment of 7 kinds of parameters is necessary.

-15 : Shortest verage time (Respons is fast, not stable)

0 : Initial value (Respons is relatively slow, stabilized well)
+6 : Longest average time (Respons is slow, stabilized)

It is recommended to use between -10 and +1

In the following cases,
It may be improved by decreasing the setting value (shortening the average time).

· Tidal current value does not easily approach the true value.

· Tidal current display value is small continues.

· The respons is slow and can't detect the tide (current-rip

If it is set to less than -10, In most situations the display value of the tidal current does not stabilize
(large variation) and it is hard to use.

If it is not stable even if it is set to a value greater than +1, there are bad factors that affect
measurement.

By operating the STC knob, change the measurement setting value of 7 items.
TIDE PROCESS
TIDE AVE. PROCESSING TIME 1
TIDE AVE. PROCESSING TIME 2
TIDE RESPONSE TIME 1

TIDE AVG. PROCESSING TIME 2 = 7  5 (Same kind of filter operation as the 628.)
TIDE RESPONSE TIME 1 = 6  3 (Same kind of filter operation as the 628.)
TIDE RESPONSE TIME 2 = 0 (Standard setting)
FILTER SETTING 1 = B1 (Standard setting)
FILTER SETTING 2 = K3 (Standard setting)
FILTER SETTING 6 = M5  M3 (Same kind of filter operation as the 628.)

Below, change depending on the preferences and circumstances.
TIDE DATA UPDATE TIME = MOMENT  FAST (It reduces the variation of the display value.)

The following configuration changes is
the setting that priority to extreme importance to response-oriented.

Response is faster than the standard set of JLN628.
However, in order to easily influenced by the disturbance, the variation will increase.
Adjustment of response (stability) is, please go tide ava. processing time 1,2.
( The following is related to Ver.3.1.1.21.
Depending on the version of the software, the standard value and the setting item,
there is a different thing. )

BTM ADJUSTMENT = +2  0 (Adjusted in accordance with change of tide process.)
TIDE PROCESS = J3  J3 or J4+ (Adjusted in accordance with
change of response-oriented)
TIDE AVG. PROCESSING TIME 1 = 6  6～9 (Time constant filter about 20s ～ 120s)
TIDE AVG. PROCESSING TIME 2 = 7  Short (Same kind of filter operation as the 628.)
TIDE RESPONSE TIME 1 = 6  Short (Same kind of filter operation as the 628.)
TIDE RESPONSE TIME 2 = 0  -3 (Same kind of filter operation as the 628.)
FILTER SETTING 1 = B1 (Standard setting)
FILTER SETTING 2 = K3  K1 (Adjusted in accordance with change of response-oriented)
FILTER SETTING 6 = M5  M1 (Adjusted in accordance with change of response-oriented.)

Below, change depending on the preferences and circumstances.
TIDE DATA UPDATE TIME = MOMENT  FAS T (It reduces the variation of the display value.)

Filter settings will mutually influence each item each other.
Therefore, in the above-mentioned two settings, different response time for the setting of the

About shallow water mode

It is a setting item which functions on the measurement limit in a shallow sea
region.
If shallow water mode is selected, measurement of a current will be attained at the
place of bottom depth shallower than usual, but the influence of the following
comes out.

- A possibility that a current value will become unstable at a place about deeper
than 50 m in the bottom of the sea depth becomes high.

- A possibility that a bottom tracking ship speed will become unstable at a place
about deeper than 50 m in the bottom of the sea depth becomes high.

- At the bottom of the sea depth about deeper than 50 m, a possibility of losing the
bottom of the sea becomes high.

- Compared with the case of a standard, the accuracy of a current value may

become low.

- Compared with the case of a standard, the tracking performance of a current

value may become slow.

About stabilization of current

It is a setting item which functions on the operation of a current.
In the following case, a setup of a current operation filter is changed to a preliminary
setting group.

- In the case of the setting value (ship speed value) is a minus value, when ship
speed is slower than the value

- In the case of the setting value (ship speed value) is a plus value, when ship speed
is quicker than the value.

Preliminary setting group: The head of a setting subject name has a notation of "+."

Example: + BT average time 1

As for this function, a good result may be obtained in the following situations.

- Usually navigate at 5 knots or more, and when carrying out a fishery, it becomes

less than 5 knots.

- While carrying out the fishery, the echo by fishing gears can check with an echo

screen.

- Or while carrying out the fishery, the muddiness generated with fishing gears etc.
can check with an echo screen.

- Although it is usually satisfactory, when a fishery is begun, a current value differs

from a true value.

- The current value which became once unusual does not show a true value easily
in the usual movement state.

In the situation of fulfilling these conditions, switch speed is set as "-5", and the usual
filter setting is set as tracking performance serious consideration, and a preliminary
setting group is set as stability serious consideration.
