Safety Cautions
i
㻌
zSafety Cautions z
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 maintain, 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.
It is necessary to perform first aid immediately.
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.

Specific Procedures for Cardiopulmonary Resuscitation (CPR)
1. Check the scene for safety to prevent secondary disasters
a) Do not touch the injured or ill person in panic when an accident has occurred. (Doing so may
cause electric shock to the first-aiders.)
b) Do not panic and be sure to turn off the power. Then, gently move the injured or ill person to a
safe place away from the electrical circuit.
2. Check for responsiveness
a) Tap the shoulder of the injured or ill and shout in the ear saying,
"Are you OK?"
b) If the person opens eyes or there is some response or gesture,
determine it as "responding." But, if there is no response or
gesture, determine it as "not responding."
3. If responding
a) Give first-aid treatment.
4. If not responding
a) Ask for help loudly. Ask somebody to make an emergency call
and bring an AED.
• Somebody has collapsed. Please help.
• Please call an ambulance.
• Please bring an AED.
• If there is nobody to help, call an ambulance yourself.
5. Check for breathing
a) Look to see if the chest and abdomen of the injured or ill person are rising and falling.
b) If the injured or ill person is breathing, place the recovery position and wait for the arrival of the
emergency services.
• Position the injured or ill person on the side.
Are you OK?
Please call an
ambulance.
Please bring an AED.

reflected off the sea bottom and picked up again by the transducer. The JFE-700 also has
the following functions:
(1) depth alert, (2) power fail alert, (3) output of depth data, (4) output of depth and power fail
alerts.
1.2 Feature
The JFE-700 features the following:
• Three display modes; standard, history, and docking.
• Depth data for last 48 hours in memory to play back the past sounding information.
• Dual frequency mode and two transducers are available in option. (*requires an optional
equipment)
ConformstotheIMOPerformanceStandard
• When the depth becomes shallower than a previously set value, a depth alert is issued by
buzzer and LCD display.
• When power is cut to the main unit, a power fail alert is issued by buzzer and LCD display.
• Contact signals can be output for both depth and power fail alerts.
• Data on depths can be output.
