Safety Precautions
The operators are asked to observe the following safety precautions.
DANGER : Do not use flammable gasses such as anesthetic gas, oxygen or hydrogen, or flammable
liquid such as ethanol, near the system, because there is danger of explosion.
WARNING
:
1. Only medical personnel fully trained in clinical examination techniques can use the
system.
2. Connect the power plug of the system to the wall receptacle properly grounded and
meeting the ratings indicated on the rating nameplate.
3. When the system is connected with other equipments, be sure to connect their
equipotential terminals before inserting any of their power plugs into a receptacle, and also,
be sure to remove the power plugs from receptacles before disconnecting the
equipotential terminals.
4. Use peripherals and optional parts provided with the system or recommended. Use cables
provided with the system. Use other peripherals or cables may degrade system
performance or even cause electric shock.
5. Do not connect the system to receptacles that control current to devices such as
life-support systems and are equipped with the same circuit breakers and fuses as those of
the system. If the system malfunctions and generates an overcurrent, or when there is an
instantaneous current at power ON, the circuit breakers and fuses of the buildings supply
circuit may be tripped.
6. No waterproof device is applied to the system. Do not use the system in any place
with the possibility of water penetration. There is risk of electric shock if any water is sprayed
on or into the system.
7. Use the system only in the environment specified in this manual.
8. Use transducers specified in this manual. Using transducers not specified in this
manual may damage the system and transducer or even cause an accident such as a fire.
9. Use the transducer carefully. In case that the human body contacts the scratched
transducer surface, immediately stop using the transducer and contact our company’s
Customer Service Department or your local distributor. Using scratched transducer may
cause electric shock.
10. If finding any abnormality in the system or transducer during the scan, stop scanning
immediately and turn off the system.
11. The system and accessories are neither disinfected nor sterilized before they are
sold. Disinfect or sterilize transducers and needle-guided brackets as the transducers’
manuals describe before using them.

12
www.ValueStore.us [e-mail]
12. After disinfecting or sterilizing accessories, thoroughly clear chemicals from the
accessories. Residual chemicals may damage the accessories and cause injury.
13. Do not let the patient contact the system or other equipments. If the system or other
equipment are defective, electric shock may occur.
14. Do not subject transducers to knocks. Using defective transducers may cause electric
shock.
15. Do not open the shell or panel. Opening the shell or panel when the system is
connected to the receptacle may cause short circuit or electric shock.
16. Before moving the system, power it off, close the control panel and then remove
all connections (including connections to transducers). Then hold the system’s handle
to move the system to a proper location carefully.
17. Before cleaning the system, power it off and remove the power plug from the receptacle
to avoid electric shock.
18. To avoid system damage or electric shock, do not remove the power plug before
turning off the system.
19. Use ultrasound gel complying with local regulations.
CAUTION
:
1. This manual does not describe clinical examination techniques. Selection of proper
clinical examination technique must be based on specialized training and clinical
experience.
2. There is no risk of high-temperature burns during routine ultrasound examinations. To
prevent high-temperature burns, do not apply the transducer to the same spot on the
patient for a long time. Apply the transducer only for as long as required time for
diagnosis.
3. Ensure the system date and time are consistent with current date and time. If they are
not consistent, misdiagnosis may occur.
4. Always keep the system dry. Do not move the system quickly from a cold place to a
warm one. Condensation or water drops formed may cause short circuit. Nerve
disorders. Observe the local safety/health regulations.
5. If the circuit breaker is tripped or the fuse is blown, it indicates that the system or
peripherals have problems. In these cases, do not repair by yourself but contact
our company’s Customer Service Department or your local distributor.
6. Do not place any object on the system.
7. Ensure other equipments are secured before moving the system. Otherwise, the
equipments may fall and cause injury.
8. Ensure proper measurement targets and images and measurements are performed in
valid image area. Incorrect measurement results may cause misdiagnosis.

13
NOTE
:
1. Do not use the system in the vicinity of strong electromagnetic field (for example a
transformer), which may affect the performance of the monitor.
2. Using devices transmitting RF signals in the vicinity of the system may affect the
system’s performance. Do not use or take any devices intentionally transmitting RF
signals such as cellular phones, transceivers and radio-controlled products in the room
placing the system.
3. Transport, store and use the system under the circumstance specified in this manual.
Additionally, store and use the system in a clean location where there is no direct
sunlight, no sudden changes in temperature, no condensation, few dust, no vibration,
and far from heat generators.
4. After turning off the system, wait at least 10 seconds before turning it on again.
Otherwise, failure may occur.
5. Before connecting/disconnecting the transducer, turn off the system or stop emitting
(freeze the image). Otherwise, the system or transducer may malfunction.
6. After using the transducer, remove the gel on it.
7. If the system is used in a small room, the room temperature may rise. Proper
ventilation must be provided.
8. Do not cover radiation holes on the system.
9. Only engineers of our company or authorized by our company can replace the fuses.
10. Only perform operations described in this manual.
11. Do not modify system parameters.
12. Deterioration of electrical and mechanical safety characteristics (such as generation of
a leakage current or deformation/abrasion of mechanical parts) and of image sensitivity
and precision may occur over a period of time. Check and maintain the system
periodically to ensure system performance.
13. To dispose of the system or any parts contact our Customer Care Department or your
local distributor first. Our company does not assume any responsibility for damage
resulting from disposal of the system without consulting our company.
